Section 1-5 - Audio Output Considerations

WARNING: AUDIBLE SIGNALS MAY MASK MEDICAL EQUIPMENT MONITORING ALARMS.

WHERE MEDICAL EQUIPMENT MONITORING ALARMS ARE IN USE, DO NOT USE AUDIBLE SIGNALS; PROVIDE VISUAL NOTIFICATION APPLIANCES IN HIGHLY VISIBLE LOCATIONS.

CAUTION: The output of the audio system may not be heard in all cases. Sound can be blocked

or reduced by walls, doors, carpeting, wall coverings, furniture, insulation, bed coverings, and other obstacles that may temporarily or permanently impede the output of the audio system. Sound is also reduced by distance and masked by background noise. The output of the audio system may not be sufficient to alert all occupants, especially those who are asleep, those who are hearing-impaired, those who are wearing devices that plug or cover the ears, and those who have recently used drugs or alcohol. The output of the audio system may not be heard by an alert person if the output device is placed in an area which is isolated by a closed door, or is located on a different floor from the person in a hazardous situation or is placed too far away to be heard over ambient noise such as, but not limited to, running water, traffic, air

If live microphone announcements, audible tones and/or voice messages cannot be readily heard and understood clearly within the protected areas as intended, it will be necessary to increase the number and/or sound output intensity of speakers within those areas so that they are heard and understood

clearly when activated

conditioners, machinery or musical appliances

Section 1-6 - RF Interference

The SAFEPATH® Panel has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at owners expense.

Section 1-7 - General

Each manufacturer's fire alarm control panel, and notification appliances operate differently and have different features. Before specifying, installing, operating, testing, maintaining or servicing a system, carefully read the installation, operation and testing manual for each piece of equipment and applicable codes.

Wiring Guidelines

Although the SAFEPATH Panel products incorporate signal verification and noise filtering circuitry on their inputs, induced voltages or noise on the input wiring can cause improper operation. Therefore, use shielded twisted pair wire for all dry contact input wiring.

The shield of each cable should be connected only at one end. Each shield of each cable that connects to the SAFEPATH knockout locations on the chassis (see Figure 3-17 on Page 3-15).

The National Electrical Code (NFPA-70) defines two types of circuits for protective signaling systems:

power limited circuits and non-power limited circuits. The SAFEPATH limited.

WARNING: ALL SAFEPATH

SHOULD BE ROUTED AWAY FROM ANY HIGH VOLYAGE OR HIGH CURRENT WIRING (SUCH AS AC OR DC POWER WIRING, AUDIO POWER WIRING, AND MOTOR OR RELAY ACTUATION WIRING). DRY CONTACT INPUT WIRING SHALL BE INSTALLED IN SEPARATE CONDUIT. FAILURE TO DO SO MAY CAUSE ELECTRICAL SHOCK RESULTING IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS.

CAUTION: The National Electric Code limits the maximum number of conductors that can be

installed in conduit and wiring boxes depending on the size of the conduit, the volume of the boxes, and the gauge of the wire used. Make sure that wiring used for

SAFEPATH

Panel installation complies with the latest NEC, NFPA, Local, State,

County or Province requirements.

Field Wiring Connections

All SAFEPATH

Panel wiring terminals are designed to accept #12 AWG through #22 AWG wiring (one wire per terminal). Proper wire gage considerations for the NAC Circuit must take into account current requirements versus length of run.

Prepare System Wiring Diagram

1. Prepare a system-wiring diagram to include all Notification Appliances, ancillary equipment, and

internal connections and power sources as required.

Visual Notification Appliance Output Wiring

Available alarm strobe current is a maximum of 2 Amps at 24VDC. Table 3-1 shows available strobe current using the standard calculation for a Temporal Code 3 signal. The SAFEPATH

Panel does not include any optional modules. Complete calculation information for other configurations is located in Section 3-8 Backup Battery Calculations.

Wire gauge may vary for each visual notification appliance output circuit on the panel. Wire gauge selection should involve consideration of all factors including, wire loop length, maximum current draw of each appliance, number of appliances, and maximum voltage drop allowable.

• Strobe NAC has a 24VDC, 2.0 amps maximum output

• Strobe NAC meets Class B supervision requirements for notification appliance circuits.

• Each output circuit shall have a UL LISTED, 10K Ohm, 1W, EOLR installed across the last visual

notification appliance. If the output is unused, a UL LISTED, 10K Ohm, 1W, EOLR shall be placed across the output terminals. Each amplifier module contains the required number for the supervised outputs. If more are needed, recommend using Wheelock, Inc.

Central Amplified Speaker Notification Appliance Output Wiring

The audio alarm current of the amplifier module depends on the number of speakers on the circuit, length and gauge of wire of the audio circuit, and the audio mode in use.

When laying out each NAC circuit for the speakers, calculate the total wattage required. A good engineering practice is to not exceed 85% of the amplifier rating that you plan to use. If your calculations exceed this, an amplifier having increased power capacity is required or replacing the entire SAFEPATH Panel with greater capacity.

Wire gauge may vary for each audio appliance output on the panel. When:

• Speaker (with transformer) appliances are used with supervised audio amplifier module (central amplified outputs). Wire gauge selection should involve consideration of all factors including, wire length, appliance power ratings, and the number of appliances.

3-6

• The central amplified output is either a selectable 25, 70.7 or a 100 volt audio output, rated for 40, or 80 watts maximum, depending upon the amplifier and its configuration.

• The output meets Class B supervision requirements for notification appliance circuits.

• Each output circuit shall have a UL LISTED, 10K Ohm, 1W EOLR installed across the

last audio notification appliance. If the output is unused, it shall have a UL LISTED, 10K Ohm, 1W EOLR across the output terminals. Each amplifier module contains the required number for the supervised outputs. If more are needed, recommend using Wheelock, Inc.

WARNING: ALL PROTECTIVE SIGNALING SYSTEMS REQUIRE PERIODIC TESTING. ALL

PROTECTIVE SIGNALING SYSTEM EQUIPMENT SHALL BE TESTED BY QUALIFIED PERSONNEL AT LEAST TWICE A YEAR FOR PROPER OPERATION, OR MORE OFTEN IF REQUIRED BY CODES, REGULATIONS AND LAWS. FAILURE TO MAINTAIN AND TEST PROTECTIVE SIGNALING SYSTEM EQUIPMENT CAN RESULT IN NOT DETECTING EQUIPMENT FAILURE THAT CAN CAUSE PROPERTY DAMAGE AND SERIOUS PERSONAL INJURY OR DEATH TO YOU AND/OR OTHERS DURING AN EMERGENCY SITUATION.

Section 3-7 – Ground Fault Detection Sensitivity Adjustment

Ground fault detection sensitivity can be adjusted for a set point between 40K Ohms and 500K Ohms.

Selecting a high resistance set point will increase the circuit sensitivity to ground fault conditions. A high resistance may cause many false trouble conditions.

Selecting a low resistance will decrease the circuit sensitivity and will greatly reduce susceptibility to false trouble conditions. The lower resistance allows for lower ground fault resistance before a ground fault conditions occurs.

Before the sensitivity is adjusted, it is imperative to correct (clear) all trouble conditions.

NOTE: The ground fault detection sensitivity set-point shall be the same value as the FACP.

Adjustment Procedure

1. Place "GRND FLT ENB DIP switch in the ON position (SW4, POS 1). See Figure 3-18 on Page 3-17.

2. Disconnect the wire between earth ground and the earth ground terminal on the Mother Board. (See Figure 9-2 on Page 9-5 for location.)

3-18

3. Rotate the shaft of the Ground Fault Detection Sensitivity potentiometer (R53) fully counterclockwise. (See Figure 9-2 on Page 9-5 for location) The potentiometer is a 12-turn device, there will be need to rotate the shaft repeatedly. The potentiometer produces a clicking sound when rotated beyond its end point.

On the Mother Board (SCMB), place a resistor with the desired set-point value (40K Ohm to 500K

Ohm, +/- 5% Tolerance) between the +24VDC terminal on TB4 and the earth ground terminal. See Figure 3-10 on Page 3-10.

5. Slowly rotate the shaft of the Ground Fault Detection Sensitivity potentiometer clockwise. When a ground fault is indicated by the trouble LED's, the sensitivity set-point is set correctly.

6. Disconnect the resistor used to set the sensitivity level.

7. Reconnect the wire between the earth ground terminal on the Mother Board and earth ground.

Section 3-8 - Battery Care and Backup Battery Calculations

Installation and Care of Sealed Lead Acid Batteries

Sealed lead acid batteries are designed to operate in standby service for approximately five years. This is based upon a normal service condition where there is an ambient temperature of 20 degrees C (68 degrees F) and batteries are completely discharged once every three months. LENGTH OF SERVICE LIFE WILL BE DIRECTLY AFFECTED BY THE NUMBER OF DISCHARGE CYCLES, DEPTH OF DISCHARGE, AND AMBIENT TEMPERATURE.

Use Guidelines:

Avoid installation and/or operation in close proximity to heat sources. While the operating temperature range is 0 to 49 degrees C (32-120 degrees F), battery life will be maximized at an ambient temperature of 20 degrees C (68 degrees F).

Batteries may generate ignitable gases. Because of this, batteries shall be installed in a wellventilated location, away from spark producing equipment.

Batteries shall not be installed in an atmosphere where organic solvents or adhesives may be present. The batteries shall not be cleaned with oils, thinners, or similar substances. The case and cover of the batteries are ABS plastic resin, which may suffer damage from these chemicals.

Batteries shall not be installed in a heavy vibration or shock location.

Batteries shall have a minimum separation of ¼” between cells.

Insulated gloves shall always be worn when handling batteries.

WARNING: Batteries shall not be crushed, incinerated, or dismantled. The electrolyte

Batteries of different capacities, age, or manufacturer shall not be used together.

Battery Storage

Batteries which are to be stored for an extended period of time should be given a supplement charge monthly. Batteries should never be stored in a discharged condition.

The self-discharge rate of batteries is approximately 3% per month when the storage temperature is maintained at 20 degrees C (68 degrees F). The self-discharge rate will vary depending upon temperature. Cooler temperatures cause the self-discharge rate to decrease. Warmer temperatures cause the self-discharge rate to increase.

contains sulfuric acid, which can cause serious damage to eyes and skin. If contact does occur, flush with water and seek immediate medical attention.

Calculating Backup Battery Requirements

A battery calculation worksheet is available at the back of this manual for assisting in calculating battery backup.

It is necessary to calculate the current draw for battery backup requirements, The current requirements depend on the system configuration and the optional modules installed. Battery Backup current has two separate calculations that are added together. They are Standby Current and Alarm Current.

CAUTION: The SAFEPATH

Power Supply generates 24VDC at a maximum of 6 Amps. The sum of the currents from all modules, speaker circuits, and Strobe NAC circuits, and Speaker Amp circuits (when SALL-15S are used) determine the current output of the panel and cannot exceed 6 Amps. If the SAFEPATH

Panel output current exceeds 6.0 amps, it is recommended that strobe circuits be routed through an external power supply.

Standby Current

Standby current consumes the largest part of the storage battery capacity.

Table 3-4 represents the Standby Current of the Single Circuit SAFEPATH signal as the supervision signal. Standby calculations can use the appropriate value from this table. The Single Circuit SAFEPATH

Panel Models in this table contain the Power Supply (DCPS), Digital

Voice Module (MDX-2) and the listed amplifiers.

Standby Current from any optional module used is listed in Table 3-5. These values added to the Panel current complete the total Standby current for the panel

Standby Current Calculating Procedure

1. From Table 3-4, select the desired value of current from the proper model.

2. From Table 3-5, select the standby current from all modules selected for the panel and add them to the value of Step 1. (If multiple RMS-2 Modules are used, calculate the standby current for each one.)

3. Multiply the results of Step 2 by the number of standby hours required. (i.e. 24 or 60). Record this value as the Standby Amp-hours.

Alarm Current

Table 3-7 lists the alarm current for each amplifier.

If no strobes are installed the strobe current is zero. If strobes are installed, add the current ratings of the strobes.

UL alarm speaker current calculations are measured with a full SIN wave input with a maximum output are as follows:

2. Using Table 3-5, add up the alarm currents of all optional modules. If multiple Remote Microphone Stations (RMS-2) are used, calculate the alarm current of just one

3. Add together the strobe current from the amplifiers NAC circuit.

4. Total the results of Steps 1 through 3.

5. Divide Step 3 results by 12 (5 minutes of alarm) or 4 (15 minutes of alarm) and record this value as Alarm Amp-hours.

Calculating Backup Battery Requirements

Good engineering practices recommend the total Amp-hours required for backup should not exceed 80% of the Backup Battery capacity.

Backup Battery Calculation Procedure

1. Add the total Standby Current to the total Alarm Current.

2. Multiply Step 1 by 1.25. This is the minimum Backup Battery requirement for this Panel.

3. Record results on the battery calculation worksheet at the end of this manual.

• Operator's Console

• Supervision

• Visual Notification Appliance Output Circuit Supervision

• Audio Notification Appliance Output Circuit Supervision

• Amplified Speaker Notification Appliance Power Output Supervision

• Amplifier Supervision

• Remote Microphone Station Supervision (Optional RMS-3)

• Actions that Initiate Alarms

Section 4-2 - Operator’s Console

An operator’s console, which allows for manual override of the automatic message playing, is provided. The operator’s console includes a microphone, a RESET pushbutton, a TROUBLE ACKNOWLEDGE pushbutton, and a main AUTOMATIC/MANUAL switch. There are two LEDs to indicate NORMAL for normal operation and TROUBLE for any Panel trouble condition. Opening the enclosure door accesses the operator’s console.

Section 4-3 - Supervision

A trouble condition indicates that the supervisory functions have detected a malfunction in the panel. When a trouble condition is detected, the panel may not be able to receive and/or remember message requests from the control panel. The installer and/or user must make sure that any message requests to the panel during a trouble condition are reactivated if necessary, when the panel is returned to normal.

If a trouble condition is detected by any of the supervisory functions, the panel Form C status relay (normally energized) will change state, the green NORMAL LED will turn “OFF”, and the amber TROUBLE LED will turn “ON”. The status relay contact closure must be properly connected to and used by the control panel to indicate a system trouble. At the same time an amber trouble location LED will identify the location of the trouble condition. If a trouble condition is indicated, follow the procedures in Chapter 7 "Troubleshooting”.

WARNING: DO NOT LEAVE THE PANEL IN A TROUBLE CONDITION AS, IT MAY NOT

PLAY WARNING MESSAGES WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS. IF THE PANEL INDICATES A TROUBLE CONDITION:

(1) PROVIDE UL REQUIRED ALTERNATIVE SIGNALING AND (2) HAVE QUALIFIED SERVICE PERSONS IMMEDIATELY REPLACE

UNIT(S) THAT HAVE MALFUNCTIONED.

WARNING: MESSAGES REQUESTED BEFORE AND DURING A TROUBLE CONDITION MAY

NOT BE HEARD, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO YOU AND/OR OTHERS. IF MESSAGES REQUESTED BEFORE AND DURING A TROUBLE CONDITION ARE STILL NECESSARY, THEY SHOULD BE REPEATED WHEN THE SAFEPATH NORMAL.

Visual Notification Appliance Output Circuit Supervision

The visual notification appliance output circuit is supervised for open and short circuits when the output is de-energized. Output circuit supervision requires installation of the supplied UL LISTED, 10K Ohm EOLR on the output circuit. Any sensed trouble will illuminate the “STR” LED on the amplifier module. See Figure 7-1 on Page 7-2 for LED location.

Audio Notification Appliance Output Circuit Supervision

The audio notification appliance output circuit is supervised for open and short circuits when the output is de-energized. The circuit is unsupervised when the output is energized. Output circuit supervision requires installation of the supplied UL LISTED, 10K Ohm EOLR on the output circuit. Any sensed trouble will illuminate the “SPK” LED on the amplifier module. See Figure 7-1 on Page 7-2 for LED location.

Amplified Speaker Notification Appliance Power Output Circuit Supervision

PANEL IS RETURNED TO

The amplified speaker notification appliance power output circuit supervised for open and short circuits when the output is de-energized. Output circuit supervision requires installation of the supplied UL LISTED, 10K Ohm EOLR on the output circuit. Any sensed trouble will illuminate the “PWR” LED on the SALL-15S module. See Figure 7-1 on Page 7-2 for LED location.

Amplifier Supervision

A supervisory tone plays through the amplifier during standby for supervision purpose. Any sensed trouble illuminates the “AMP” LED on the amplifier module. See Figure 7-1 on Page 7-2 for LED location.

Ground Fault Supervision

The SAFEPATH® Panel supervises for ground fault conditions on field wiring that is not electrically isolated. The supervised wiring includes contact inputs, visual NAC circuits, audio NAC circuits, amplified speaker NAC circuits, trouble audible output circuits, remote microphone station wiring and MDX-2 wiring. All other wiring is electrically isolated. Ground fault supervision may be enabled and disabled by switching the ground fault enable switch on (GND FLT ENB, SW4, POS 1). See Figure 3-18 on Page 3-17.

Remote Microphone Supervision (Optional RMS-2)

The audio circuit is supervised on the Remote Microphone Station PCB.

Section 4-4 - Actions That Initiate Alarms

Chapter 5 - Operational Procedures

Section 5-1 - Operator Instructions

The SAFEPATH® Panel provides an operator console for manually activating the panel. The operator console includes a microphone, a green NORMAL LED, a yellow TROUBLE LED, a “RESET” momentary switch, a TROUBLE ACKNOWLEDGE momentary switch, and a MANUAL/AUTOMATIC switch. The operator interface allows the operator to manually override automatically playing pre-recorded messages with live announcements or an evacuation tone, to silence internal and external trouble audibles, and to ascertain if the panel has detected a trouble condition. The operator instructions on the dead front panel are shown in Figure 5-1 on Page 5-3.

The TROUBLE and NORMAL LEDs identify to the operator the condition of the SAFEPATH yellow TROUBLE LED will be illuminated whenever there is a trouble detected by the Panel. If no troubles are detected, the green NORMAL LED will be illuminated.

The TROUBLE ACKNOWLEDGE push-button allows the operator to silence the trouble audibles, both internal and external. When a trouble condition is detected, both the internal and external trouble audibles are sounded. When the ACKNOWLEDGE push-button is depressed, the internal and external trouble audibles will be silenced. The trouble audibles will resound for subsequent trouble conditions. The Form C trouble output contact will remain in the trouble condition and the TROUBLE LED will remain illuminated until all trouble conditions have been corrected.

The AUTOMATIC/MANUAL switch has two positions, manual (down) and automatic (up). When the AUTOMATIC/MANUAL toggle switch is in the automatic position, pre-recorded messages may be selected to play via dry contact inputs. When the AUTOMATIC/MANUAL switch is in the manual position, pre-recorded messages will not play, the visual notification appliances are energized, and the evacuation tone sounds.

a. Check appropriate fuse on MDX-2. b. Replace Motherboard.

If, after the above procedure is completed, the trouble condition persists, the trouble condition is caused by broken LED's on the MDX-2 Module. The LED's on the MDX-2 module are not field replaceable. Digital voice modules with broken LED's shall be replaced immediately, following the “SAFEPATH

Module Replacement Procedure”, set forth at the end of this section.

7-9

Procedure I

On the Single Circuit Mother Board (SCMB), the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “ON”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and the TROUBLE LED is “OFF”, then the digital voice module may be completely inoperative. This condition is caused by:

1. Too low input voltage on the digital voice module.

2. Missing or improperly installed program memory EPROM.

3. Broken TROUBLE LED (digital voice module is operative if this is the cause).

4. Failed circuitry on the digital voice module.

Perform the following:

1. Verify that the input voltage exceeds the minimum operating voltage.

2. Verify that the program memory EPROM is present and inserted into slot S15 properly.

3. Attempt to play a message file. If the file plays then the digital voice module trouble indicator LED is

broken.

If, after the above procedure is completed, the trouble condition persists, the trouble condition is caused by failed circuitry on the Digital Voice Module. There are no field correctable failed circuitry problems on the digital voice module. Digital Voice Modules with failed circuitry shall be replaced immediately, following the “SAFEPATH

Module Replacement Procedure”, set forth at the end of this section.

Procedure J

ON”, then the digital voice module is partially or completely inoperative.

The Digital Voice Module can be rendered inoperative by:

1. Too low input voltage on the Digital Voice Module.

2. Failed audio channel on the Digital Voice Module.

3. Failed Message Kit (SMK or PMK)

4. Other failed circuitry on the Series MDX-2 or Output Channel Module (MDV-OCM).

If the error was either due to the first or third cause, the Digital Voice Module will not play messages. If the error was due to the second cause, the Digital Voice Module might play messages.

When the digital voice module is rendered inoperative, perform the following:

1. Verify that the input voltage is 24 ± 5VDC.

2. Attempt to play messages on all installed audio channels.

3. Remove Message Kit (SMK or PMK). If the “TROUBLE” LED on the MDX-2 goes to a 2 Blink pattern,

then the Message Kit is in error. Replace Message Kit.

There are no field correctable failed circuitry problems. Digital Voice Modules with failed circuitry shall be replaced immediately, following the “SAFEPATH

Module Replacement Procedure”, set forth at the end

of this section.

Procedure K

On the Single Circuit Mother Board (SCMB), the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “ON”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and the TROUBLE LED flashes a “2-blink pattern”, then a message memory EPROM error has occurred on the MDX-2 module. A message memory EPROM error may be caused by:

1. Pre-programmed message memory EPROM's not installed into Series MDX-2 in proper order.

2. No messages programmed into message memory EPROM's.

7-10

3. Missing or improperly installed message memory EPROM's.

4. One or more of the messages were not programmed completely.

5. Failed circuitry on the MDX-2.

If the error was due to one of the first four causes, the trouble will clear automatically when the cause is corrected. The first four causes should only occur when power is first turned on to the Series MDX-2.

When a message memory error is indicated, perform the following:

1. Verify that the preprogrammed message memory EPROM's were installed in the correct sockets on

the Series MDX-2. See Figure 9-3 on Page 9-7 for proper chip location. An EPROM must always be installed in socket S14. If between one and two minutes of message memory is required, the first EPROM must be installed into socket S14 and the second EPROM into socket S12.

2. Verify, at least one message is programmed into the message memory EPROM's.

3. Verify that all message memory EPROM's are inserted into their sockets properly.

4. Verify that there are no partially programmed messages on the message memory EPROM's. This can

only be done using commands on the serial port, which is located on the optional Ground Fault Detection/Computer Interface

Module.

If, after the above procedure is completed, the trouble condition persists, the trouble condition is caused by failed circuitry on the Series MDX-2. There are no field correctable failed circuitry problems on the Series MDX-2. Series MDX-2's with failed circuitry shall be replaced immediately, following the Replacement Procedure, set forth at the end of this section.

Procedure L

On the Single Circuit Mother Board (SCMB), the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “ON”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and the TROUBLE LED flashes a “4-blink pattern”, then an audio channel error has occurred. An audio channel error may be caused by:

1. Too low an audio level while playing a message.

2. Pause in message while playing a message that lasts longer than 3 seconds.

If the error occurs while playing a file, then the error was due to the first cause. If the error occurs immediately after turning on power to the Series MDX-2, the error was due to the second cause.

If the error was due to either cause while playing a message, the trouble will clear automatically when audio is again detected while a message is playing. If the error is due to the third cause, the trouble will clear automatically when the output is no longer loaded down while a message is playing. If the error was due to the fourth cause, the trouble will clear automatically when the module is properly installed and input power is cycled off and on.

When an audio channel error is indicated, perform the following:

1. Have the message re-recorded, shortening duration of the pause.

Section 9-2 - Single Circuit Mother Board (SCMB)

Wheelock, Inc. Part Number 108974

The Single Circuit Mother Board provides all signal handling capabilities between itself and the amplifier modules, terminal blocks for output wiring, and connectors for handling signals from the digital voice module.

The Single Circuit Mother Board is illustrated in Figure 9-2 on Page 9-5.

A single amplifier module is connected to the SCMB.

A single channel from the Digital Voice Module (MDX-2) is connected to the SCMB. The digital voice module is mounted on the power supply cover and wired to the Mother Board. The digital voice module channel will play through the amplifier module installed.

The microphone input is located in the lower right corner of the board and is used for live voice announcements.

Form C contacts are available for remote monitoring of Alarm Status and Trouble Status. Also remote trouble power is available at 24VDC, 0.100 Amps, that is non-supervised.

Single Circuit Mother Board supervises the Digital Voice Module (MDX-2), Power Supply, and the amplifier module (SAA-40S, SAA-80S/SE, or SALL-15S) for proper operation. The microphone is supervised for connection.

The channel play contacts from the digital voice module (MDX-2) are monitored to determine their status (e.g. active or inactive). If the channel play contact is inactive, the control module routes a supervision tone to the amplifier circuit module and monitors the amplifier for functionality. If the channel playing contact is active, the control module routes the audio from that MDX-2 line output to the amplifier circuit module. Wiring used to monitor the channel play contacts and to route the line output from the Digital Voice Module is supervised for open and short circuit conditions.

The Power Supply module is supervised for two conditions: low AC input power, and low battery voltage. The wiring between the controller module and the battery charger is supervised for open and short circuit conditions.

The amplifier module is supervised for two failure conditions: field wiring trouble conditions and amplifier audio output trouble conditions. The SCMB only supervises the audio output during standby conditions. When either a message is playing from the Digital Voice Module or a live announcement is being made from the microphone, the field wiring and audio output are not supervised.

The strobe NAC circuit can be used with standard non-synchronized strobes or the circuit can be place in the SYNC mode for synchronizing Wheelock, Inc. synchronized strobes. Synchronization is accomplished by turning “ON” DIP Switch SW5, Position 3 (SYNC) on the SAMB.

The strobe NAC circuit on the amplifier module is also supervised in the standby mode for field wiring trouble conditions.

If at any time a trouble condition is detected, the SCMB will energize the internal audible, the external trouble audible circuit, and transfer the Form C trouble contact to the trouble position, turn “OFF” the NORMAL LED, and turn “ON” the TROUBLE LED.

There are two fuses on the Mother Board. F1 is the fuse for the external trouble audible circuit, and F2 is the fuse for the Remote Microphone Station power. Both fuses are rated at 0.5A. See Figure 9-2 on Page 9-5 for fuse location.

Section 9-3 - Digital Voice Module (MDX-2)

Wheelock, Inc. Part Number: 105094

The Digital Voice Module (MDX-2) provides playback capability of pre-recorded messages. The MDX-2, when activated, provides a pre-recorded tone and/or message to the Single Circuit SAFEPATH which then broadcasts it through the amplifiers and to the audio appliances.

The MDX-2 can have up to 8 pre-recorded messages that can be initiated by dry contact closure or open collector for each one. Figure 9-3 on Page 9-7 shows the location of these inputs. Up to 2 minutes of audio storage are recorded on UV-erasable EPROM memory chips. Any dry contact closure or open collector can include Acknowledgment of the playing file and Reset initiation. (The reset switch is required to be in a locked enclosure.)

The memory chips are normally recorded at Wheelock, Inc. The Standard Message Kit (SMK), which has 8 common messages and tones, is programmed for a single channel output. The Programmed Message Kit (PMK) is tailor made to the customer’s desires. The location of these kits are shown on Figure 9-3 on Page 9-7.

Fuse F1 fuses the 24VDC power input.

Figure 9-3 shows the MDX-2 as it is mounted in the panel.

Section 9-5 - Supervised Audio System Amplifier/Signal Circuit

Module, 40 Watts (SAA-40S)

Wheelock, Inc. Part Number: 105493

The supervised audio system amplifier/signal circuit module, 40 watts (SAA) provides audio amplification for the SAFEPATH The amplifier contains a switch mode power supply, a linear amplifier, and supervision circuitry.

The switching power supply is used to provide a constant DC voltage to the amplifier while the input voltage is allowed to fluctuate over its operating range. The amplifier amplifies the low-level 600-ohm audio to 40 watts output at either 25V or 70.7V. The supervision circuit monitors field speaker wiring integrity, field strobe wiring integrity, and amplifier functionality.

The module can be field configured for either 25V or 70.7V output. The configuration is done using a twoposition slide switch (S1) on the printed circuit board. One position (down) configures the amplifier to have a 25V output and the other position (up) configures the amplifier to have a 70.7V output. See Figure 9-5 on Page 9-10 for switch location.

The amplifier supervises both the strobe field wiring and the speaker field wiring with a DC current. The strobe field wiring is supervised with a reverse polarity technique, which applies a DC voltage with one polarity to supervise the wiring and then reverses the polarity to energize the strobes. The speaker field wiring is supervised with a DC current, which is removed when audio is being played. Both field-wiring circuits are only supervised in the standby state. The amplifier is supervised by monitoring the amplifier output for audio. The state of each of the three supervision features is indicated via three LEDs on the module. See Figure 9-5 on Page 9-10 for LED locations.

There are two fuses on the printed circuit board, F1 and F2. Fuse F1 is the main fuse for the entire board. F2 is the fuse for the strobe power. See Figure 9-5 on Page 9-10 for fuse locations.

Two UL LISTED 10K Ohm, 1W, End of Line Resistors are included with this module.
