Field Wiring

TX/RX Data

Terminal block 1 (TB1) on the rear panel connects the access panel data line to the ADVANCE system
control cabinet. A twisted pair cable (minimum Category 3) should be used for this connection. Observe
cable conductor polarity (+/−) when making connections at the control cabinet: (+ connects to + and −
connects to −). No damage will occur if the polarity is reversed, but the access panel will not function.
Maximum cable distance to the control cabinet is 3 km when using No. 24 AWG (Category 3) cable.
Refer to Figure 7 for terminal block location.

Power

The access panel is supplied with a modular power cord. Loosen the power connector lock on the rear of
the access panel. Plug the power cord into the connector and retighten the power connector lock. Plug
the other end into a grounded ac electrical outlet (120/230 V ac). Refer to Figure 7 for power cable
location.

N

OTE: The access panel does not have an on/off power switch and will power up immediately upon

plugging in the power cable. The ADVANCE System control cabinet must also be powered and running
before the access panel is operational. LEDs on the access panel will flash and the display will read “No
communication with ADVANCE” until data communication is established with the ADVANCE control
cabinet.

Audio In

Terminal block 2 (TB2) on the rear panel allows an external audio source to be connected to the panel.
Connect the audio source using a shielded twisted pair cable (No. 18–24 AWG).

The audio is summed with the handset microphone and can be broadcast to the system party line when the
hookswitch is activated. For broadcast to the system paging speakers, the hookswitch and page switch
must be activated. Refer to Figure 7 for terminal block location.

Remote Speaker

Terminal block 2 (TB2) on the rear panel allows an external speaker to be connected to the access panel.
Connect the speaker using a twisted pair cable (No. 18–22 AWG)

The speaker will broadcast the same audio as the front panel speaker but will not be affected by the front
panel volume control. Refer to Figure 7 for terminal block location.

LED Driver Outputs

The DB-25 connector on the rear panel provides 24 LED driver outputs for powering external indicators,
mechanical relays, etc. These drivers are in parallel with the front panel LED indicators on the keypad
switch. Therefore, when the front panel LED is on, the corresponding output pin is on. The pin out of the
connector correlates to the LED number, e.g. pin 1 is for LED 1, pin 2 is LED 2, etc. Pin 25 is +5 V dc to
power the remote indicators or relays.

Operation

The access panel operator is capable of voice communication, system control functions and viewing the
system operating status on the LCD display. The following paragraphs provide a general overview of the
available access panel features. Operational details for each access panel are determined by software
programming at the ADVANCE System control cabinet.

In general, the access panel handset is used for paging and party line communication. Push-button
switches are used for a variety of system control functions.

Push-Button Switch Summary

Each push-button switch function and LED indicator (next to the switch) is programmable. Typical
switch functions include alarm activation/reset, paging zone selection, or beacon activation/reset, but
other special functions are available through system programming.

Paging and Party Line Operation (typical)

Complete the following steps to make a page announcement from an access panel.

1. Lift the handset from the cradle.

2. Select the desired paging destination(s) or all call. The LEDs of the selected switches illuminate.

3. Press and hold the handset pressbar switch.

4. After the short “wait” tone is heard, speak directly into the microphone to broadcast your

announcement.

5. Release the handset pressbar when complete.

6. Upon releasing the pressbar switch, the access panel handset is connected to party line 1 or 2. The

paged individual(s) responds by picking up a station’s handset and turning the selector switch to party
line 1 or 2. Party line communication is not broadcast over the system speakers. Other individuals
can also pick up a handset and join the conversation at any time. Always return the handset to the
cradle following a page or a party line conversation.

OTE: To cancel any selected destination push-button switch, press the switch again and the LED will

N

extinguish. The access panel automatically deselects the paging destination(s) after a page is completed.

Paging Confirmation Tones

When paging from an access panel, a short “wait” tone will be heard in the handset receiver when the
page switch is depressed. Do not talk until the tone ceases. When the tone ceases, the page request has
been granted by the system control cabinet. If a busy tone is heard, the page request has been rejected and
the operator must try again later. The page rejection occurs when a higher priority page or alarm is in
progress at the time of the page request.

Timeout Features

Each access panel can be programmed to limit handset paging time and the amount of time the handset
can be in use or off-hook. These features are often used to identify handsets that have accidentally been
left off-hook or to restrict an access panel from being in use for prolonged periods of time.

Page Timeout – This sets amount of time the access panel can generate a page. If the limit is exceeded,

the page will cease and a busy tone is heard in the handset receiver. A trouble report will be sent to the
control cabinet. If the handset page switch is released, the page timer is reset. The page timeout can be
disabled or set for 1–25 minutes in 1-minute intervals.

OTE: By default, the page time-out for access panels is disabled.

N
Off-Hook Timeout – This sets amount of time the access panel can be in use or off-hook. If the limit is

exceeded, handset operation will cease and the access panel will be placed electrically on-hook. A
trouble report is sent to the control cabinet. The handset remains inoperative until it is physically placed
back on-hook. The off-hook timeout can be disabled or set from 1–25 minutes in 1-minute intervals.

OTE: By default the off-hook time-out for access panels is disabled.

N

Handset Paging Pre-announcement Tones

An access panel page can be preceded by one of two available tones. Tone selection is based on the
system mode of operation at the time of the page (normal or alarm). The “Splash” is a Hi-Lo tone
approximately 1 second in duration. The “Alert” is a swept tone approximately 1 second in duration.

OTE: By default, the splash tone is enabled.

N

Activating an Alarm

Activate an alarm from the access panel as follows:

1. Select the desired destination using the zone push button(s) if configured. The destination could be a

single zone, a group of zones, or all zones. The LEDs of the selected zone switches illuminate.

2. Select the appropriate alarm push button. The alarm broadcasts into the selected zones, and the LED

of the selected alarm illuminates during the broadcast.

3. For access panels equipped with an E

NTER push button: Press the ENTER push button after pressing

the alarm push button to activate the alarm in the selected zones.

OTES:

N

1. To cancel any concurrent alarm, press the C

ANCEL CURRENT push button or the RESET ALL push

button. This cancels all alarms that are currently playing or that are in the alarm queue.

2. Alarms may also be configured to play immediately when the alarm push button is pressed. In this

case a zone selection is not required. The alarm’s destination is pre-configured in the system
programming.

Sonalert

The sonalert is an audible indicator and its control signal is paralleled with LED output #20. It is
typically configured to sound when a new message is available on the LCD. If configured as described

above, press the ACK/NEXT push button to display each new message. The sonalert turns off once the

last available new message has been displayed.

Lamp Test Feature

The lamp test feature is used to verify that the access panel indicators are functioning properly. When the

L

AMP TEST push button is pressed, the switch indicators illuminate, and the panel sonalert will sound.

OTE: The LAMP TEST and PREVIOUS push buttons do not include an indicator.

N

Options

Two options are available on the access panel.

The first option is a protection cover for the push-button switches. See Figure 11. It consists of a clear
cover with a hinge and magnetic latch. The door must be opened to access the keypad switches
preventing accidental push-button activation.
