1 Description and Specifications
1.1 General Description
The RTS Model 803 Master Intercom Station is an up­dated replacement to the popular Model 802. By employ­ing many of the technological breakthroughs that have occurred since the design of the 802, RTS has been able to integrate into the 803 the complete circuitry for all 802 base features and options except squawk. For example, call signaling is now standard on all twelve intercom chan­nels. For applications requiring 4-wire operation, IFB panel emulation or ISO panel emulation the circuitry is al­ready there; you simply install an option cable to the back panel, set one or two internal DIP switches (IFB and ISO emulate only) and you're ready to go. For all other applica­tions, everything you need is "in the box".
In terms of form, fit and function the 803 can directly re­place the 802 with the following exceptions: 1) squawk is not supported on the 803; 2) many users do not require a front panel gooseneck microphone, so that is now sup­plied as a separate plug-in style microphone (unlike the 802 microphone which was permanently mounted); 3) the 803 includes built-in DC blocking for the intercom chan­nels, so when connecting to powered intercom channels that were previously connected to an 802, the external iso­lation capacitors are no longer required and may have to be removed for best audio performance; 4) although sel­dom done in practice, the 802 could be DC powered; the 803 cannot.
In addition to it's role as a product replacement for the 802, the 803 also adds several new features in response to the increasing communication needs of a variety of users. Following is a general description of 803 features. Ex­panded descriptions of these features, a detailed compari­son and contrast with the 802, and a list of specifications may be found on the following pages.
1.1.1 General 803 Features
Audio Inputs and Outputs: 12 intercom channels
(channels1-12); 3 auxiliary channels (channels13-
15); 2 program inputs; 2 headsetdynamic-mic inputs and headphone outputs; 2 headset carbon-micinputs and headphone outputs; 2 electret panel mic inputs;1 built-inspeaker and 1 switched speaker output;1 un­switched,balanced mic output (hot mic).
Three Operating Modes: 1) normal operation, where
front panel controls are used for intercommunications
2) setup mode, where front panel buttons access the user-programmable setup features; 3) DTMF mode, where the keypad is used for telephone dialing on a selected intercom channel.
Audio Input Control: Complete control of audio mix
for all audio inputs via a combination of user con­trols, setup trimmers and the RS232/RS485 port. All audio inputs are assignable, via setup mode, to left headphone, right headphone, speaker, or any combi­nation.
Two-Wire and Four-Wire Operation: two-wire opera-
tion (with or without nulling) or four-wire operation independently selectable for each intercom channel via front panel setup mode; two-wire operation is standard (balanced or unbalanced); four-wire inter­com channel operation requires an optional 50-pin connector); auxiliary channels 13 & 14 are four-wire only; auxiliary channel 15 is two-wire only. All chan­nels (intercom and auxiliary) support simultaneous two-way communication (full duplex).
ISO Operation: Compatible with RTS VIE-306 Video
ISO System; interfaces with external RTS VCP-6 or VCP-12 ISO Panels, or emulates these panels inter­nally (requires one optional 50-pin connector for VCP-6 emulation; two for VCP-12 emulation).
IFB Operation: Compatible with RTS Model 4000
IFB System; interfaces with external RTS Model 4001 or 4002 IFB panels, or emulates these panels in­ternally (requires one optional 50-pin connector for Model 4001 emulation; two for Model 4002 emula­tion). Also supports "local IFB", where any channel may be configured as a stand-alone IFB.
User-Programmable Setup Features: A varietyof pro-
grammable features allow the user to customize, sim­plify, and "automate" communication tasks. (Features list includes original 802 features plus new features.)
Control Signals: Call send and receive (compatible
with TW intercom system), with 3 chime tones (or no chime) selectable for call send; talk-off send (compat­ible with RTS TW intercom system); global reset send (compatible with RTSVIE-306 Video ISO Sys­tem); DTMF send (for touch-tone dialing).
Control Inputs and Outputs: 6 DPDT relay outputs
and 1 external switch contact input, all assignable via the front panel setup-mode; 12 dedicated, open-col­lector keying outputs (one for each intercom chan­nel); 1 RS232/RS485 port for remote control, programming, and monitoring.
Note: control signals are applicable to the 12 intercom channels only, and not to the 3 auxiliary channels.

For example, access the LOCAL IFB feature by pressing button 2 dur­ing setup mode. Access presets by tapping any one of the buttons labeled PRE 1 through PRE 6. Labels that are not italicized are operating features and not setup mode fea­tures.
Note: some italicized labels are not setup mode features, but are submenu items for use with a particular setup mode feature.
1.1.3.2 Setup Mode Features
801 emulation: Default: 801 emulation disabled.Internal/external ISO select: internal is used when the
803 emulates a VCP panel; external is used when the 803 connects to an external VCP panel, or when ISO is not used. Default: external.
ISO listen disable: turn off all activeconference chan-
nel listen buttons during ISO: Default: off (listens not disabled during ISO).
ISO enable/disable: Default: disabled.IFB talk disable: turns off all active conference chan-
nel talk buttons during IFB. Default: off.
Jumpers
Separate jumpers set the "off" brightness for the keypad buttons and for the talk/listen buttons. Available settings are high, low and off.
2W/4W Setup
Each intercom channel may be set for two-wire operation, four-wire operation, or both (not applicable to auxiliary chan­nels). For two-wire operation, nulling may also be optionally turned on or off. Thus, theintercomchannels may be indi­vidually programmed to operate with a variety of inputs and outputs. For example,two-wire operation won't work with a typical two-way radio, which often requiresa four-wire, un­balanced connection. R TS "TW" belt packs and intercom channels, of course, operatein two-wiremode, and nulling is normally activa tedwhen connecting to TW devices.
Default setting: all channels set for two-wire operation with nulling.
AUTO LISTEN Setup
Each listen button may be individually programmed for auto listen. When auto listen is assigned to a channel, that chan­nel's listen button will automatically turn on when there is an incoming call signal from another intercom station.
Default setting: auto listen is disabled for all channels.
7
AUTO TALK Setup
Each talk button can be individually programmed to auto­matically activate when an incoming call signal is re­ceived on its intercom channel. The microphone also activates, so that the803 user can talk to the caller with­out having to press any buttons.
Default setting: auto talk disabled for all channels.
Default setting: caller ID is disabled on all intercom chan­nels.
CHIME SELECT Setup
Chime select lets you select one of 3 chime tones for in­coming call announcement on the intercom channels. The currently selected tone always sounds at power-up or after a reset.
BILAT SELECTSetup
If one or more of the auxiliary channels 13-15 are not be­ing used with the ISO and IFB options, these channels may be assigned to front-panel buttons (usually unused keypad buttons) for talk and listen activation.
Default setting: channels 13 through 15 unassigned.
BUFFER RECALL Setup
The 803 has an internal buffer which stores the current status (on or off) for all 24 talk and listen buttons. The contents of this buffer can be recalled and stored in any one of the 6 presets (the PRE 1 through PRE 6 buttons on the keypad). You can then activate that preset button at any time during normal operation to recall the saved talk and listen button settings.
Default setting: N/A
BUTTON LOCK Setup
This feature locks selected talk and listen buttons in the on or off position. You must also use this feature to unlock buttons.
Default setting: all buttons unlocked.
CALL DISABLE Setup
Default setting: a single high-low tone
EXT CONTACT Setup
This feature lets you activate any one button on the front panel (except CALL & SETUP) using an external switch. You can also activate a group of buttons by assigning those buttons to a preset and then activating the preset with the external switch.
Default setting: the external switch activates the MIC ON button on the keypad.
INSTANT MIC Setup
In order to talk to an intercom channel, both the MIC ON button and the talk button for that channel must be on. In some cases it may be convenient to have both of these acti­vate when the talk button is pressed. This is referred to as "instant mic".
Default setting: instant mic is disabled for all channels.
LATCH DISABLE Setup
Most front panel buttons can operate in both momentary and latching mode. You may not want certain buttonsto have the ability to latch (for example, a button that talks to a radio transmitter). You can disable latching for these buttons.
This feature disables or enables call signal reception on se­lected intercom channels. When call signal reception is disabled on a channel, there will be no chime tone or but­ton flash to indicate an incoming call. Outgoing call sig­nals are not affected.
Default setting: call reception enabled for all intercom channels.
CALLER ID Setup
Caller ID causes the listen button for an intercom channel to flicker when audio is being received on that channel. This provides a visual cue of which channel is talking. You can set caller ID to provide this indication when the listen button is on and/or off.
Default setting: latching operation enabled for all buttons that support latching.
LOCAL IFB Setup
Any of the intercom channels 1-12 can beconverted into a local IFB channel. (Not applicable to channels 13-15). A local IFB channel normally sends a program feed to a re­mote listener. By pressing the talk button for the local IFB channel, the 803 station operator can interrupt the pro­gram feed and then talk to the remote listener. The pro­gram source for a local IFB channel can be either of the program 1 or 2 inputs, or the listen input for that channel.
Default setting: local IFB is off for all channels.
8
MIC SELECT Setup
This feature selects which microphone inputs areacti­vated by the PANEL ON button in both the on and off po­sitions.
Default setting: the PANEL ON button selects the front panel gooseneck microphone in the on position and the front panel headset microphone (either carbon or dy­namic) in the off position.
PRESET EXCLUDE Setup
Selected talk and listen buttons may be excluded so that they cannot be assigned for activation using the preset but­tons.
Default setting: talk turns off listen is deactivated for all channels.
TALK TURNS ON LISTEN Setup
You can set the talk button for any channel so that activat­ing that talk button will automatically turn on the listen button.
Default setting: talk turns on listen is deactivated for all channels.
TOTAL MUTE Setup
Total mute lets you turn off all talk and listen buttons by tapping a single button.
Default setting: no talk or listen buttons are excluded from assignment to presets.
PRESETS Setup
Any combination of talk and listen buttons may be as­signed for activation by any one of the 6 preset buttons.
Default setting: no presets setup.
RELAY Setup
Any of the 6 built-in relays may be assigned for activation by selected front panel buttons.
Default setting: no relays assigned.
SP/L/R (Speaker Left/Right Select) Setup
Each audio input can be directed to the speaker, the left headphone, the right headphone, or any combination of the three.
Default setting: all audio inputs are assigned to the speaker and to both the right and left headphones.
SPECIAL PURPOSE Setup
This feature is only available for special-order products.
TALK TURNS OFF LISTEN Setup
Occasionally, activating a talk button while the listen but­ton is on may cause feedback, echo or other undesirable sounds. This may only happen on selected channels, or it may happen on all channels in certain environments or with certain audio sources. You can eliminate this prob­lem by setting selected listen buttons to automatically turn off while their associated talk buttons are on.
Default setting: no total mute button assigned.

The 803 can be set for voice-activated microphone. When this feature is enabled the microphone will remain off when you are not speaking into it. When you do speak, the microphone will turn on, and your voice will be trans­mitted on any channels that have talk buttons activated.
Default setting: vox disabled.
1.1.4 803 Compatibility with RTS Video ISO Sys­tem
The 803 can be connected to an external VCP-6 or VCP­12 Video ISOPanel. For external ISO, button activation at the VCP panel causes deactivation of all conferencechan­nel talk buttons at the 803 (listen button deactivation may also be setup via an internal 803 DIP switch), and the 803 mic audio is automatically routed to the VCP system.
The 803 can also emulate a VCP-6 or VCP-12 ISO Panel. VCP-6 emulation requires installation of an optional 50­pin cable and resetting internal DIP switches. VCP-6 emu­lation takes over 3 intercom channels (and their talk and listen buttons) and auxiliary channel 15. VCP-6 emulation can be installed along with Model 4001 IFB panel emula­tion. VCP-12 emulation is similar to VCP-6 emulation, but requires installation of two 50-pin option cables. VCP­12 emulation takes over 6 intercom channels and auxil­iary channel 15. Also, IFB panel emulation is not possible when VCP-12 panel emulation is installed. (However, lo­cal IFB is still possible on any unused intercom channels.)

1.1.5 803 Compatibility with RTS Model 4000 IFB System and Local IFB
1.1.6 Comparison of 803 and 802
1.1.6.1 Retained Features
The 803 can be connected to an external 4001 or 4002 IFB Panel. For external IFB, button activation at the IFB panel causes deactivation of all conference channel talk buttons at the 803, and the 803 mic audio is automatically routed to the IFB system.
The 803 can also emulate a 4001 or 4002 IFB Panel. Model 4001 IFB Panel emulation requires installation of an optional 50-pin cable and resetting internal DIP switches. Model 4001 emulation takes over 3 intercom channels (and their talk and listen buttons) and auxiliary channel 13. Model 4001 emulation can be installed along with VCP-6 ISO Panelemulation. Model 4002 IFBPanel emulation is similar to Model 4001 emulation, but re­quires installation of two 50-pin option cables. Model 4002 emulation takes over 6 intercom channels and auxil­iary channels 13 and 14. Also, VCP emulation isnot possi­ble when Model 4002 emulation is installed. However, external ISO is still possible.
Any intercom channel that is not being used for intercom­munication or IFB/ISO panel emulation may be config­ured as a local IFB channel. This channel can be set to normally monitor a program input at either the program 1 or 2 input. Or, if the local IFB channel is operated in 4­wire mode, the listen input may be used as the program source. Pressing the talk button for that channel discon­nects the program input and causes the 803 operator's voice to be heard at the IFB output.

2.2 Option Cable Installation
2.2.3 4-Wire Option Cable Notes
2.2.1 General Information
The connector openings for the option cables are labeled on the back panel as follows:
ISO 1 Connector: Used for VCP-6 and VCP-12 ISO Panel Emulation; provides connections for ISO1 through ISO6.
IFB 1 Connector: Used for 4001 and 4002 IFB Panel Emulation; provides connections for IFB1 through IFB4 and SA1 (Stage Announce 1)
IFB 2 / ISO 2 Connector: Can be used with the ISO1 con­nector for VCP-12 Panel Emulation (provides the ISO7 through ISO12 connections). Or, can be used with the IFB1 connector for 4002 IFB Panel Emulation (provides the IFB5 through IFB8 and SA2 connections)
2.2.2 Back Panel Connector Installation
1. Remove the 12 top cover screws and remove the cover.
2. Select thedesired connector opening in the back panel. Remove the 3/16 jack screw and the phillips screw that hold the mesh screen and white plastic cable re­taining clip in place.
3. Insert the 50-Pin"D" connector of the option cable into the connector opening. The connector should be ori­ented the same way as the TWO WIRE LINE CON­NECTOR that is already installed.
4. Reinstallthe white plastic cable retaining clip and the screws. Note that the "D" connector has threaded in­serts, so the hex nuts that were originally used are no longer required.
5. Refer tothe following installation notes for each option cable to complete the installation.
Connect the 4-wire cable to J55 on the main circuit board. The red wire on the cable corresponds to pin 1 of J55. Note: there are no internal DIP switches directly related to the 4-wire option. You configureindividual channels to operate in 4-wire mode via the front panel setup mode. See "2W/4W Setup", page 43 for details.
2.2.4 IFB and ISO Option Cable Notes
2.2.4.1 General Notes
The priority and tally connectors are identified in Figure
2. Only one priority connector is used for each cable. It determines who gets controlling access to IFB's and ISO's when there is more than one IFB or ISO panel in the inter­com system. Priority 1 overrides all panels set to priority 2, 3, or 4; priority 2 overrides priority 3 and 4 etc. When an IFB or ISO button is pressed at a panel which has a higher priority, any lower priority panels will be discon­nected from that IFB or ISO until the buttonis released on the higher priority panel. If the same IFB or ISO button is activated on two panels with the same priority, both will be able to talk to the IFB or ISO at the same time.
The tally connector is used in all cases. It distributes but­ton-pressed signals throughout the intercom system to no­tify all other IFB or ISO panels when any IFB or ISO button has been pressed.
Important! The priority and tally connectors can be in­stalled backward if the correct location of pin 1 is not ob­served. Also, the connectors can be misaligned so that all pins are not connected. Check carefully when installing.

When you install an IFB or ISO option cable and set the internal DIP switches as noted in the following para­graphs, specific front panel buttons will be reserved for the installed option. The button insert sheet provides standard button labels for these reserved buttons. See "Front Panel Button Inserts", page 17 for details.
2.2.4.2 IFB 1 Cable Notes
Connect the desired priority connector to J325 on the
main circuit board. Connectthe tally connector to J326.
Set DIP switch S1-3 (page 16 ) to the ON position*.
DIP switch S2-8 may optionally be set to the on posi­tion if you want all talk buttons to automatically shut off whenever any IFB button is activated.
When installing button inserts for IFB 1 (page 17)
note that different buttons are used, depending on whether or not another IFB or ISO connector is in­stalled.
Use a 50-pin cable to connect from the IFB 1 connec-
tor to a Model 4010 Central ElectronicsUnit. Typical connections are shown in Figure 20, page 40. Refer also to your Model 4010 Manual; if you are only us­ing the IFB 1 connector and not IFB 2, connections are the same as for a Model 4001 Control Station.
2.2.4.3 IFB 2 Cable Notes
The IFB 2 cable should only be installed in addition
to the IFB 1 cable. If you install and activate thisca­ble, do not install and activate any ISO option cables.
Connect the desired priority connector to J327 on the
main board. Connect the tally connector to J328.
Set DIP switch S1-4 (page 16 ) to the ON position to
activate the IFB 2 connector*. (You should already have set DIP switch S1-3 to the on position to acti­vate the IFB 1 connector.)
2.2.5 ISO 1 Cable Notes
Connect the desired priority connector to J329 on the
main circuit board. Connectthe tally connector to J330.
Set DIP switches S2-4 and S2-6 (page 16 ) to the ON
position to activate and use this connector*. DIP switch S2-5 may optionally be set to the ON position if you want all conferencechannel listen buttons to automatically shut off whenever any ISO button is ac­tivated (all conference channel talk buttons always shut off during ISO).
When installing button inserts for ISO 1 (page 17)
note that different buttons are reserved,depending on whether or not another IFB or ISO connector is in­stalled.
Use a 50-pin cable to connect from the ISO 1 connec-
tor to a Model VIE-306 Video ISO Electronics Unit. Typical connections are shown in Figure 20, page 40. Refer to your Model VIE-306 Manual for further in­formation. If you are only using the ISO 1 connector and not ISO 2, connections are the same as for a Model VCP-6.
2.2.5.1 ISO 2 Cable Notes
The ISO 2 cable should only be installed in addition
to the ISO 1 cable. Also, if you install and activate this cable, you cannot install and activate any IFB op­tion cables.
Connect the desired priority connector to J331 on the
main board. Connect the tally connector to J332.
Set DIP switch S1-4 to the on position to activate the
ISO 2 connector*. (You should already have set DIP switches S2-4 and S2-6 to the on position to activate the ISO 1 connector.)
Install the button inserts (page 17).
Install the button inserts (page 17).Typical system connections are shown in Figure 18,
page 38. Refer also to your Model 4010 Central Elec­tronics Manual. When using both the IFB 1 and IFB 2 connectors, connections are the same as for a Model 4002 Control Station.
* Any time you change any of these DIP switch settings, you must perform a reset in order for them to take effect. All
previous setup mode programming will be erased during the reset.
Typical system connections are shown in Figure 19,
page 39Refer to your Model VIE-306 Video ISO Electronics Manual for connection information. When using both the ISO 1 and ISO 2 connectors, connections are the same as if you are connecting a Model VCP-12 Control Station.

2.3 DIP Switch Settings
Table 3. DIP switch S2 settings
Unless you are using the 803 for IFB or ISO operations, you will probably not need to change any of the DIP switch settings. However, briefly review the tables below and make any required or optional changes before pro­ceeding. Figure 4 showsthe locations of the DIP switches. Access the switches by removing the 12 screws securing the top cover.
Switches that are grayed-out in the tables require a reset after changing, and will cause any setup-mode program­ming to be erased. All other switches do not require any reset. See "Resetting the 803", page 19.
If you activate any of the DIP switches for the IFB or ISO connectors on the back panel, change the front panel but­ton inserts as described on the next page. Otherwise, pro­ceed to "Setting the Key Code Switch", page 17.

2.6 Setting the Key Code Switch
KEY
The key code switch on the back panel con­trols access to the user-programmable setup mode features. (The setup mode features are described starting on page 43.) Key code switch settings are as follows:
0: No access permitted (no one can program the 803) 1-9: User must enter this number before accessing setup mode A-F: No restrictions on access to setup mode (default)
Note: The key code switch has a stop at the 0 setting. Do not attempt to rotate the switch through 0 to F.
To restrict access, select one of the settings 0 through 9. Otherwise, leave the setting in the default position. If you change the switch setting, the new setting will take place immediately. Note that if you select the 0 position, you will need to gain access to this switch if you ever need to change any 803 programmable features.

2.7 Resetting the 803
Prior to mounting the 803, perform a power-up reset.This will allow any DIP switch changes to take effect, and it will allow you to verify the operation of the front panel displays. To perform the power-up reset, simply plug in the power supply module.
At the start of reset, the front panel buttons will light in se­quence. Then one listen button and one keypad button will light simultaneously to display the version number. The listen button displays the high digit and the keypad button displays the low digit. For example, if the LISTEN 5 button and the "7" button on the keypad are both lit, the version number is 5.7.
After the version number is displayed, the currently se­lected chime tone (if any) willsound. This is the tone that you will hear for incoming call announcement. (You can change this tone or turn it off. See "Chime Select Setup". page 46.) At this time, the SPK ON button will also light and remain on.
A warm reset only occurs underthe followingcondi­tions:
At power up if DIP switch S1-7 is set to the off posi-
tion AND NO HARDWARE DIP SWITCH SET­TINGS HAVE BEEN CHANGED ANDTHE BACKUP BATTERY IS FUNCTIONING COR­RECTLY. (DIP switches that affect hardware opera-
tion are grayed-out in Tables2 or 3 , page 16.)
When the user forces a warm reset during normal op-
eration (see below) AND NO HARDWARE DIP SWITCH SETTINGS HAVE BEEN CHANGED AND THE BACKUP BATTERY IS FUNCTION­ING CORRECTLY.
Forcing a cold reset
Simultaneously press and hold the talk 1, 5, and 9 buttons and the listen 2 button. Then, release the talk buttons while continuing to hold the listen 2 button. After the front panel lights begin to cycle release the listen 2 button.
Note: The rest of this page provides a detailed explanation of the reset operation. You may skip this and proceed to "Mounting the 803" on the next page; however, note that changes to DIP switch settings after you have pro­grammed the 803 (using setup mode, as described starting on page 43) could erase your programmed settings.
The 803 has two reset modes: cold reset and warm reset. A cold reset restarts the 803 and erases all setup mode pro­gramming. All front panel buttons are turned off (except the SPK ON button, which always starts up in the on posi­tion). A warm reset restartsthe 803 and resets all front panel buttons to the positions they were in before the reset was initiated.
A cold reset occurs under the following conditions:
DIP switch S1-7 is set to the on position and the 803
is powered up.
The user forces a cold reset during normal operation.
(See "Forcing a Cold Reset", below.)
The user changes any of the DIP switches that are
grayed-out in Tables 2 or 3 (page 16) and then per­forms a cold or warm reset by any means.
Forcing a warm reset
Simultaneously press and hold the talk 1, 5, and 9 buttons, then release all 3 buttons.
The backup battery fails and any kind of reset by any
means occurs.

2.8 Mounting the 803
2.9 803 Connections
Note: If the mounting location for the 803 provides access to the back panel controls and connectors, you should be able to mount the 803 at this time. Otherwise, perform the connections and adjustments as described in the following sections before mounting the 803.
The 803 mounts in any standard equipment rack or bay and occupies 2 rack spaces (3.5 inches high). Depth is
10.5 inches behind the front panel. Allow an additional 2 to 3 inches for connectors.
If the 803 will be used with a VCP-6/VCP-12 ISO Panel or a 4001/4002 IFB Panel, it is generally located within easy reach of these devices. General consideration should also be given to the visibility of the controls and indica­tors from the operator's position to avoid eye or neck strain during extended usage and to assure unobstructed vision of other personnel or equipment. If necessary, dis­cuss the positioning of the 803 and related components with personnel who will have to use them to assure the best setup. Once the 803 has been mounted, you should be ready to connect it to the intercom system. Proceed to the next page.
Refer to the connector pin-out tables and notes on the fol­lowing pages for information about each connector. For examples of connector usage, refer to the diagrams follow­ing the connector pin-out tables. After you connect the 803, you may have to configure one or more features prior to operation. See "Setup Mode", starting on page 43 .

Intercom Audio
By default, 803 channels 1-12 are set for 2-wire bilateral operation with nulling. This may be modified forselected channels. See "2W/4W Setup", page 43 for further details. The 803 uses a balanced configuration for 2-wire opera­tion. The 803 channels can be connected to either bal­anced or unbalanced intercom stations or channels. However, when making unbalanced connections, the noise immunity of the balanced 803 channel will be com­promised, and it is best to not distribute that channel over cabling to other points in the intercom system. If you are connecting the 803 to an unpowered (dry) intercomchan­nel, terminate that channel at one and only one point by connecting a 200 ohm, 1/4-watt resistor across the inter­com channel. If you are connecting a powered channel, termination is usually accomplished by the power supply. The 803 has built-in dc isolation, and so it is not neces­sary to use isolation capacitors when connecting to a pow­ered intercom channel.
Talk Ke ying Signal Outputs
The 12 talk keying signal outputs are activated by the 803's talk buttons. These outputs may be used to activate external devices such as relays. See "Using the Talk Key­ing Outputs", page 34.
Program 2
For a description of the program inputs, see this topic on page 22.

2.9.2 J102 Connector
Table 5. J102 connector pin-out
Relay Outputs
Each of the 6 internal relaysmaybe assigned for activation by most of the front panel buttons.See "Relay 1 Through Relay 6 Setup", page 49. The relays can be used for any audio or low-current switching requirements. For each re­lay, the normal closed contact acts like a simple closed switch (shorted to common) when the assigned front panel button is not on, and the switch contact opens when the button is activated. The normal open contact operation is the reverse of the normal closed contact. The two com­mon connections for each relay are electrically identical. All relay connections are electrically isolated from the rest of the 803 circuitry. Relayconnections are also avail­able at J108, page 28.
External Switch Contact Input (XSW)
A switch may be connected between pins 13 and 38 for re­mote operation of a front panel button. By default, switch contact closure will turn on the MIC ON button.To acti­vate some other button, see "External Contact Setup", page 46. The XSW connection is also available at J108.
Program Inputs
Program inputs 1 and 2 are balanced, line-level audio in­puts. Nominal input levelis 0 dBm. Balanced or unbal­anced sources may be connected, but use normal precautions when connecting an unbalanced source (use shielded cabling, keep leads short, avoid routing wires near high voltage etc.). The program 1 and 2 inputs are ad­justable via the PGM 1 and 2 trimmers on the front panel, and they may be assigned to either right or left head­phones or the internal speaker via front panel program­ming. The program 1 pins of J102 are electrically identical to the program 1 pins of J111; the program 2 pins of J102 are electrically identical to the program 2 pins of J101, J105 and J111. For each program source, use only one connect point.
Channels 13 and 14
J102 provides access to channels 13 and 14, which do not normally have front panel buttons assigned. Channel 13 is reserved when the Model 803 is configured for Model 4001 IFB emulation. Both channels 13 and 14 are re­served when the Model 803 is configured for Model 4002 IFB Station emulation. If one or both channels are not used for IFB, they may be used as 4-wire channels. Use the "Bilat" pins for output and the "Listen input" pins for input. See "Bilat Select Setup", page 44, to assign front panel buttons to use the channels. Note that there is no provision for call signaling, mic-off signaling or keying output signals on these channels.

2.9.8 J108 Connector
Table 11. J108 connector pin-out
Relays and External Switch
The relay and external switch connections at J108 are elec­trically identical to those at J102. See "J102 Connector", page 22.
External ISO Connection
For external ISO, the 803 is used with an externalVCP panel located adjacent to the 803. Activating any of the ISO buttons on the external VCP panel sends a control sig­nal to the 803 which causes all active talk channels to de­activate. The 803's microphone audio is then output at the bilat 15 pins on the J108 connector. This audio output is connected to the audio input of the VCP, which then sends it to the ISO system.
To connect external ISO:
Connect J108, pin 13 of the 803 to TB2, pin 2 of the VCP; connect J108, pin 25 to TB2, pin 3. Thisis the audio output connection from the 803 to the VCP.
Connect J108, pin 12 of the 803 to TB4, pin 4 of the VCP; connect J108, pin 24 to TB4, pin 3. This is the con­trol input connection from the VCP to the 803.
Set DIP switch S2-6 to ON; S2-5 to ON or OFF as de­sired; S2-4 to OFF. For DIP switch details, see page 16.
Bilat 15
As previously described, bilat 15 can be used for ISO. If ISO is not required, bilat 15 can be used asa 2-wire inter­com channel, or for audio output or input. Note that there is no provision for call signaling, mic-off signaling or key­ing output signals for bilat 15. To assign talk andlisten keys to use bilat 15, see "Bilat Select Setup", page 44. Note that there is no LISTEN control on the front panel for bilat 15. Adjust the listen level at the "R ISO" trimmer on the back panel. Adjust nulling at the "N ISO" trimmer on the back panel.

2.9.9 J109 Connector
Table 12. J109 connector pin-out
J109 can be used to connect to a computer or terminal for remote access and control of the 803. Use a standard RS232 cable (not null modem). Default RS232 port set­tings are 2400 baud*, 8 data bits, 1 stop bit and no parity. No handshaking is used. You can send commands to do any of the following:
operate all front panel buttons or read their settingsinhibit manual operation of front panel buttonsread the settings of all DIP switchesread and modify the 803's programmable memoryoperate all relays, talk/listen gates and key lines inde-
pendently of button positions
initiate a reset (warm or cold)request notification upon operator initiation of resetsend a command upon operator initiation of any func-
tion, front panel or DIP switch change
Command Structure
Most commands generally consist of 3 parts: a one- or two-character command letter, followed by a numeric modifier, followed by an operator. Commands which per­form memory operations are structured as follows: a one­or two-character command letter, followed by a memory location, followed by a memory operator. If the memory operator modifies memory, it will be followed by one or more bytes of information to be sent to memory. All com­mands must be followed by a carriage return. All com­mands, except memory load commands, are limited to 128 characters in length.

Error Handling for the RS232 and RS485 Ports
Upon detection of an error in a command, the 803 will typically ignore the command and send out an error mes­sage consisting of the letter E along with a 2 digit code as follows:
E00 syntax error E01 output buffer overflow E02 unrecognizable command E03 Unrecognized operator (+, - or ? expected) E04 numeric modifier out of range E10 RS-232 framing or parity error E20 RS-422/485 framing or parity error
Note: Relays are updated every time a button is pushed or released. This means, for example, that if the host com­puter turns on a relay, it may be turned off the next time the 803 operator pushes any button. Keying output signals and gates may also be affected if the operator pushes the button associated with that key or gate.

2.9.13 J201 Connector
J201 accepts a an electret condenser type panel micro­phone. Any microphone installed at this connector is re­ferred to as the internal panel microphone (IPM). By default, the IPM is active when the PANEL ON button is in the on position. To change this, see "Mic Select Setup", page 48. The IPM gain is adjusted via the IPM trimmer on the back panel.
2.9.14 J202 Connector
J202 accepts a stereo, dynamic-mic headset. The micro­phone for any headset connected at J202 is referred to as the internal headset microphone (IHM). By default, the IHM is active when the PANEL ON button is in the off position. To change this, see "Mic Select Setup", page 48. The IHM gain is adjusted via the IHM trimmer on the back panel. The standard 803 uses a 5-pin connector for J202. This connector is used for headsets without a mic switch. The 6-pin version accepts a mic switch input which activates the MIC ON circuit.

2.9.16 Miscellaneous Connections
2.9.16.2External ISO
2.9.16.1Local IFB
Any of the intercom channels 1-12 can beconverted into a local IFB channel. (Not applicable to channels 13-15). A local IFB channel normally sends a program feed to a re­mote listener. By pressing the talk button for the local IFB channel, the 803 station operator can interrupt the pro­gram feed and then talk to the remote listener. Three sources can be selected for the program feed: either the program 1 or 2 inputs, or that channel's 4-wire input (if the 4-wire option is installed).
To use an intercom channel for local IFB:
1. Set the intercom channel for local IFB operation and se­lect the desired program source: see "Local IFB Setup", page 47. Note: Youcan only use the program 1 or 2 inputs unless the 4-wire option is installed.
2. Connect the intercom channel to the remote listener's station. When connecting both local IFB channels and standard intercom channels to the 803, it may be convenient to usesplitters. An example for 2-wire ap­plications is shown in Figure 22, page 42. For a 2­wire IFB channel, use the appropriate pins at the J101 connector, page 21. (Note: the 2-wire channels are normally used for bi-directional audio. In this case, however, you will be using the channel for audio output only.) For a 4-wire channel, use the ap­propriate talk audio output pins at J105, page 26.
External ISO connection was discussed on page 28.
2.9.16.3Using the Talk Keying Signal Outputs
The 12 talk keying signal outputs at J101 may be used to activate externaldevices by pressing the associated talk key. A typical configuration using a relay is shown in the figure below.
Note: Since the 803 uses Darlington outputs for the talk keying signals, the "on" state for the outputs may not pull sufficiently close to ground for use as a CMOS or TTL logic control output. Some type of external signal condi­tioning circuit is recommended.

3. Connect the program source. For both 2-wire and 4­wire IFB, you may use either program 1 or 2 con­nected at any one of the following points:
Program 1
J102: page 22 J111: page 32
Program 2
J101: page 21 J102: page 22 J111: page 32
If you are using a 4-wire channel for IFB, instead of using the program 1 or 2 input you may connect program input directly to the 4-wire listen input of the channel that you are using for IFB output.
4. If desired, label the talk button for the new IFB channel to distinguish it from a normal talk button.
5. For local IFB button operation see page 55.

Figure 21. An application showing the use of both 2-wire and 4-wire circuits. Note that in this e xample, the 4-wire talk outputs use the 2-wire connector (J101).When a channel is operated in 4-wire mode, the 4-wire talk audio out­puts from the 803 use the 2-wire bilats, which are bi-directional, as outputs only. The 2-wire bilat connections are available at both J101 and J105.In this application, the 4-wire talk outputs are connected using J101.The only rea­son for doing this is to also provide access to the keying outputs of the 803.For example, it may be necessary to key a radio transmitter when talking to it.If you only need audio input/output for 4-wire circuits and do not need to use the keying signals, you can eliminate the 4024 used for 2-wire breakout and just use one 4024 for 4-wire breakout.

16) will erase all user programming that you configured
in setup mode.
3.2 Entering Setup Mode
1. If a key code was assigned during installation (page 17) first enter that code on the keypad. Otherwise, skip this step and go directly to step 2.
2. Press and hold the CALL & SETUP button for about 3 seconds. It should flash brightly during this time. When setup mode activates, the CALL & SETUP button will become brightly lit. Also, all buttons that immediately access setup features will begin to flash dimly.
3. Tap any flashing button to access its setup feature.
Note: Select a setup feature within about 13 seconds after entering setup mode. Otherwise, the 803 will automat­ically return to normal operating mode. Once a feature has been selected the 803 will remain in setup mode until you exit.
4. To exit setup mode at any time,tap CALL & SETUP again.
The following paragraphs describe how to use all of the setup features that are named on the front panel. The fea­tures are listed in alpha-numeric order.

See "2W/4W Setup", below.
3.4.2
Each intercom channel may be set for 2-wire operation, 4­wire operation, or both. For 2-wire operation, nulling may also be optionally turned on or off. Thus, the intercom channels may be individually programmed to operate with a variety of inputs and outputs. For example, 2-wire opera­tion won't work with a typical 2-way radio, which often requires a 4-wire, unbalanced connection. RTS "TW" belt packs and intercom channels, of course, operate in 2-wire mode, and nulling is normally activated when connecting to TW devices.
Default setting: all channels set for 2-wire operation with nulling
Select 2-wire/4-wire operation for selected channels as follows:

In addition to the 12 regular intercom channels which can be configured for either 2-wire or 4-wire operation, the 803 has three extra audio channels, channels 13 through 15, that don't havetalk and listen buttons associated with them. Channels 13 and 14 are 4-wire-only channels. Chan­nel 13 TALK is reserved for IFB use when DIP switch S1­3 is set to the ON position ( page 16). This switch selects Model 4001 IFB panel emulation when the optional IFB 1 connector is installed. Channel 14 TALK is reserved for IFB use when DIP switches S1-3 and S1-4 are set to the ON position (for Model 4002 emulate using both the IFB 1 and IFB 2 connectors). Channel 15 is a 2-wire-only channel. This channel is reserved for ISO use when DIP switch S2-6 is set to the ON position. (Note: the nulling adjustment for channel 15 is the "N ISO" trimmer on the back panel. See "ISO Channel 15 Adjustments", page 51.)

4 Adjustments
4.2 Front Panel Adjustments
4.1 Back Panel Adjustments
4.1.1 Microphone Level Adjustments
There are 4 trimmers to adjust input gain for the various microphone inputs. Before adjusting the gain set the MIC ON button to the on position. Also, set the PANEL ON button to the on position for a panel microphone or to the off position for a headset microphone. Note that by de­fault the PANEL ON button selects the internal panel mi­crophone in the on position and the internal headset microphone in the off position. To changethis see "Mic Select Setup, page 48.
HM (Internal Headset Microphone)
This trimmer adjusts the gain for a headset microphone connected at either the DYN-MIC HEADSET or CARB­ON-MIC HEADSET connector.
PM (Internal Panel Microphone)
This trimmer adjusts the gain for a panel microphone con­nected at the front panel of the 803.
4.2.1 VOX PM / VOX HM Adjustment
Note: You must enable the VOX feature to make this ad­justment. See VOX Enable Setup", page 50.
Note: The VOX level adjustment is affected by the set­tings of the "HM" and "PM" trimmers on the back panel. Make sure those trimmers are correctly set before proceed­ing. See "Microphone Level Adjustment", page 51.
Set the VOX level as follows:
1. Turn on a talk button.
2. Make sure the correct microphone is selected: the PANEL ON button should be on for a panel micro­phone and off for a headset microphone.
3. Speak into the microphone. If you are using a panel mi­crophone adjust the VOX PM trimmer on the front panel so that the MIC ON button lights at the desired sound level; if you are using a headset microphone adjust the VOX HM trimmer to activate the MIC ON button.
EXT HM (External Headset Microphone)
This trimmer adjusts the microphone gain for a dynamic­or carbon-mic headset connected at J111.
EXT PM (External Panel Microphone)
This trimmer adjusts the gain for a panel microphone con­nected at J111 on the back panel.
4.1.2 ISO (Channel 15) Adjustments
R ISO (ISO Receive)
This trimmer functions for channel 15 exactly like the front panel LEVEL controls function for channels 1-12. Increase or decrease this level as desired when channel 15 is receiving an audio input.
N ISO (ISO Null)
The null adjustment for channel 15 is the same as for any of the 12 regular intercom channels. See "Null Adjust­ment", at right.

4.1.3 USMB (Unswitched Microphone Balanced) Output Level Adjustment

Use this control to adjust the USMB output level at J111.
4. This completes the VOX level adjustment.Turn the talk button off.
4.2.2 PGM1 / PGM2 Adjustment
Use the PGM1 and PGM2 trimmers on the front panel to equalize any level differences between the two program inputs. You may also adjust both trimmers to raise or lower the range of the PROGRAM VOLUME control.
4.2.3 LAMP DIM Adjustment
Adjust this trimmer to set the brightness of the front panel lamps as desired.
4.2.4 Null Adjustment
When you are using a channel in 2-wire mode, that chan­nel should be balanced, or nulled, so that the outgoing sig­nal from your microphone is not fed back into your speaker and/or headphones. Any residual signal that is fed back will sound like sidetone (see the separate paragraphs on "Sidetone Adjustment", below). However, unlike side­tone, which is heard only in the headphones and will be a constant level no matter which channel you are talking to; the residual feedback from an improperly nulled 2-wire channel will be heard both in the speaker and headphones, and it will vary from channelto channel depending on the degree of imbalance in each channel.
51
The null adjustment is related to the overall impedance of the intercom channel, and is thus to a certain degree influ­enced by the number of devices connected to that channel. Therefore, best nulling will be achieved after all stations have been connected to the intercom channel. You can per­form the null adjustment using the panel mic and speaker (recommended method) or a headset. If a headset is used, you must first set the sidetone trimmer to minimum.
Note: Each channel can be set for either 2-wire or 4-wire operation, and nulling can be turned on or off for each 2­wire channel. (See "2W/4W Setup", page 43 for further in­formation.) By default, all channels are set for 2-wire operation with nulling. If nulling has been turned off for a channel, or that channel is operated in 4-wire mode, the following adjustment will have no effect.
Perform the null adjustment as follows:
1. Activate the MIC ON button.
2. Select the desired microphone source. Activate the PANEL ON button if you are using a panel micro­phone, or tun the PANEL ON button off if you are us­ing a headset. Also activate the SPEAKER ON button if you are using the speaker.
amount of sidetone is necessary for natural-sounding com­munication.
Note: If one or more channels are being operated in 2­wire mode with nulling, make sure those channels are properly nulled before setting the sidetone level.
1. Set the MASTER VOLUME and PROGRAM VOL­UME controls to minimum.
2. Activate the MIC ON button.
3. Set the PANEL ON button to the off position.
4. While speaking into the headset microphone, adjust the SIDETONE trimmer so that your voice is heard in the headphones at the desired level.
5. This completes the sidetone adjustment.
3. Activate the talk and listen buttons for the first channel that you want to adjust. If there is feedback, reduce the MASTER VOLUME.
4. While talking into the microphone, adjust the null trim­mer for that channel to minimize your own voice level in the speaker or headphones. As you minimize, or null out, your own voice level you can increase the MASTER VOLUME level, aswell as the individual LEVEL control for that channel, to help you hear bet­ter when a good null has been achieved.
Note: The null trimmers for channels 1-12 are located on the front panel. Since channels 13 and 14 are 4-wire only, no null trimmer is provided. The null trimmerfor channel 15 is located on the back panel and is identifiedas N ISO, since this channel is primarily used for ISO operation.
5. Repeat the adjustment for each remaining channel that is being operated in 2-wire mode.
6. This completes the null adjustment. If you will be using headphones with the 803, perform the sidetone adjust­ment after the null adjustment.
4.2.5 Sidetone Adjustment
The sidetone adjustment lets you set the level of your own voice in the headphones when using a headset. A certain

5 Intercom Operation
5.1 Initial Volume Adjustm ent
You can setup a talk button to automatically turn on when­ever there is an incoming call on that channel. See "Auto Talk Setup", page 44.
Prior to first use, set the MASTER VOLUME and PRO­GRAM VOLUME controls to the minimum position. Set the twelve channel LEVEL controls to about the half-on position. Later, you can adjust the individual channel lev­els up or down to balance channels that are unusually loud or soft.
5.2 Momentary vs Latching Button Operation
Most front panel buttons feature both momentary and latching operation. For momentary operation, press and hold the button to turn it on, then release it to turn it off. For latching operation, tap a button to turn it on, then tap it again to turn it off. Latching operation can be used when you want to keep your hands free for other opera­tions.
Note: Latching operation may be turned off for selected buttons. See "Latch Disable Setup", page 47.
5.3 Headset or Panel Mic/Speaker Selection
If you are using a headset, leave the PANEL ON button in the off position (unlit). You can setthe SPKR ON button (speaker on) to either on or off as desired.
You can defeat latching operation for a talk button. See "Latch Disable Setup", page 47.
You can lock a talk button in the on or off position. See "Button Lock Setup", page 45.
5.5 Listening to an Intercom Channel
To listen to a channel, activate its listen button in either momentary or latching mode. Adjust the MASTER VOL­UME control to an acceptable listening level.
As you listen to intercom channels, you may notice that some channels are louder or softer than others. In this case, adjust the individual channel LEVEL controls at the bottom of the front panel. (There is no level adjustment for channels 13 and 14. Adjust the channel 15 level via the R ISO trimmer on the back panel.)
Note: Several options can be assigned to selected listen buttons to modify their standard operation:
You can setup a listen button to automatically turn on whenever the corresponding talk button is pressed. See "Talk Turns on Listen Setup", page 50.
If you are using an optional panel microphone along with the built-in speaker, set the PANEL ON and SPKR ON buttons to the on position.
Note: You may find it useful to lock either or both of these buttons in the on or off position. See "Button Lock Setup", page 45.
5.4 Talking to an Intercom Channel
1. Activate the MIC ON button.
2. Make sure the correct microphone is selected: the PANEL ON button should be on when you are using a panel microphone and off when you are using a headset.
3. Activate the talk button for the channel that you want to talk to. Press and hold the button for momentary op­eration. Or, tap the button to latch it in the on position for "hands-free" operation.
Note: Several options can be assigned to selected talk but­tons to modify their standard operation:
You can setup a talk button so that it automaticallyacti­vates the MIC ON button. See "Instant Mic Setup", page 47.
You can setup a listen button to automatically turn off whenever the corresponding talk button is pressed. See "Talk Turns off Listen Setup", page 49.
You can setup a listen button to automatically turn on whenever there is an incoming call on that channel. See "Auto Listen Setup", page 44.
You can defeat latching operation for a listen button. See "Latch Disable Setup", page 47.
You can lock a listen button in the on or off position. See "Button Lock Setup", page 45.
5.6 Program Listen
After an acceptable listening level for the intercom system has been established, adjust the PROGRAM LEVEL con­trol to establish an acceptable listening level for any pro­gram inputs that may be connected.
5.7 Receiving Call Signals
When another intercom station calls your station, you will hear the call chime tone, and the talk button for that chan­nel will begin to flash. Activate the talk and listen buttons to communicate.
53
Note: Several options can be setup to modify the way in­coming calls are received and indicated:
Incoming call signals may be disabled on selected chan­nels. See "Call Disable Setup", page 46.
Selected talk and listen buttons may be setup to automat­ically activate on incoming call. See "Auto Talk Setup" and "Auto Listen Setup", page 44.
Any 1 of 3 chime tones, or no chime tone, may be se­lected for incoming call announce. See "Chime Select Setup, page 46.
Selected listen buttons may be setup to flicker as a caller talks to provide a visual cue of a call's origin. See "Caller ID Setup", page 46.
5.8 Sending Call Signals
To send a call signal on a specific channel:
5.10 Telephone Dialing with the Keypad
The 803 is capable of generating DTMF tones for dialing out on a phone line. If there is a telephoneinterface con­nected on an intercom channel, you can use the 803 key­pad to dial out on that channel. The actual method that you use to access the phone line varies dependingon how the 803 is connected and the type of telephone interface being used. For example, your intercom system may be configured so that activating a talk button will pick up the telephone line, in which case the following procedure may be used. Some installations, however, may require some other action to pick up a telephone line, in which case you will need to do that before the following proce­dure.
1. Tap theasterisk button (*) three times. The keypad but­tons will light to indicate that dialing mode is acti­vated, and the CALL & SETUP button will flash to indicate that this is the key to press to return to nor­mal mode. The talk buttons will also begin to flash.
1. Tap theCALL & SETUP button. It should begin to flash.
2. Within about 2-3 second, tap the talk button for the channel that you want to call. You should hear a chime tone, indicating that the call signal has been sent.
To send a call signal to a preset group of channels:
1. Tap theCALL & SETUP button. It should begin to flash.
2. Within about 2-3 second, tap the PRESET button for the group of channels that you want to call. Youshould hear the chime tone, then the CALL & SETUP but­ton stop flashing.
Note: To setup a preset group see "PresetsSetup", page 48.

5.9 Using MICS OFF to Deactivate

Microphones on an Intercom Channel
MICS OFF lets you turn off the microphones on any inter­com stations connected to a particular channel. The inter­com stations must be capable of detecting the MICS OFF signal. Send a MICS OFF signal as follows:
1. Tap theMICS OFF button.
2. Tap any talk button to send the MICS OFF signal on that channel.
Note: you must tap a talk button within about 2 seconds. You must repeat the procedure for every channel.
2. Tap thetalk button for the channel that you want to dial on.
3. Now use the keypad to dial as for a normal touch-tone keypad.
4. When you are finished dialing, tap the CALL & SETUP button to return to normal operation.
5. Activate the microphone and listen button (if required) to proceed with your conversation.
6. Turn off your talk button when finished with the call to hang up.
5.11 ISO Operation
5.11.1 ISO Operation in VCP Emulate Mode
These instructions apply to any buttons that have been configured for ISO panel emulation with the optional ISO connector(s) installed and activated as describedstarting on page 14.
If an ISO button is lit continuously, someone else is
currently talking to that ISO channel. If your 803 or external VCP is set to the same or higher priority, you will be able to talk to that ISO; otherwise, you will have to wait until the light shuts off.
To talk, activate the desired ISO button. It will flash
while active.Also, all talk buttons will shut off and the MIC ON button will light. Turn the ISO button off when finished talking.
54
Note: If listen disable has been programmed (by setting DIP switch S2-5 to the ON position, page 16) all listen buttons will also shut off during ISO operation.
Note: If talk disable has been programmed (by set-
ting DIP switch S2-8 to the ON position, page 16) all talk buttons will also shut off during IFB operation.
When you are using the 803 in VCP emulate mode,
you can use the global reset feature of the 803 to shut off all ISO buttons in the system. To do this, tap the G-RST button on the 803 keypad.
5.11.2 ISO Operation using an External VCP Panel
These instructions apply to an 803 that has been setup to work with an external VCP panel as described on page 28.
If an ISO button is lit continuously, someone else is
currently talking to that ISO channel. If your VCP is set to the same or higher priority, you will be able to talk to that ISO; otherwise, you will have to wait un­til the light shuts off.
To talk, activate the desired ISO button on the VCP,
then speak into the 803 microphone. While the ISO button is active, all 803 talk buttons will be off and the MIC ON button will be lit. Turn the ISO button off when finished talking. The 803 will return to nor­mal operation.
When you are using an external VCP, you can tap the
Local Reset button at any time to turn off allactive ISO buttons on your VCP Panel. Or, you can tap the Global Reset button to shut off all active ISO buttons in the intercom system.
