Section 1-4 - Property Insurance Recommendation

The SAFEPATH® panel is not a substitute for insurance. All users should have adequate levels of life and property insurance

Section 1-5 - Audio Output Considerations

! Warnin

! Caution:

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

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.

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 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 the user’s own 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.

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 - 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 of ¼” separation between cells. Insulated gloves shall always be worn when handling batteries.

! Warnin

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.

BATTERIES SHALL NOT BE CRUSHED, INCINERATED, OR DISMANTLED. THE ELECTROLYTE CONTAINS SULFURIC ACID, WHICH CAN CAUSE SERIOUS DAMAGE TO EYES AND SKIN. IF CONTACT DOES OCCUR, FLUSH WITH WATER AND SEEK IMMEDIATE MEDICAL ATTENTION.

3-23

Page 44

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.

Calculating Backup Battery Requirements

It is necessary to calculate the current draw for battery backup requirement, 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 Amps. The sum of the currents from all modules, speaker circuits, and

Power Supply generates 24 VDC at a maximum of 6

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.

Backup Battery Worksheet

Worksheet for assisting in calculating battery backup is available as Appendix B.

Standby Current

Standby current consumes the largest part of the storage battery capacity. Table 3-4 represents the Standby Current of the Dual-Circuit SAFEPATH supervision signal. Standby calculations can use the appropriate value from this table. The DualCircuit 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 on Page 3-26. These values

added to the Panel current complete the total Standby current for the panel

Standby Current Calculating Procedure

1. From Table 3-4 on Page 3-25, select the desired value of current from the proper Model.

Panel using the test signal as the

2. From Table 3-5 on Page 3-26, select the standby current from all modules selected for the panel and add them to the value of Step 1. (If multiple RMS-3, SPL and/or NACIM 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.

Table 3-5 lists the alarm current of the Dual-Circuit SAFEPATH® Modules. Table 3-7 on Page 327 lists the alarm current for each amplifier. If no amplifiers are installed in the amplifier slot the current for that slot is zero.

If no strobes are installed in the zone, the current is zero. If strobes are installed, add the sum of the current ratings of the strobe in each circuit to the corresponding amplifier.

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

Alarm Current Calculating Procedure

1. Using Table 3-7 on Page 3-27, calculate the alarm current for each amplifier module installed.

2. Using Table 3-5, add up the alarm currents of all optional modules. If multiple RMS-3 with an AIM-3, calculate the alarm current for one. If SPL and/or NACIM Modules are used, calculate the alarm current for each one.

3. Add together the strobe current from both amplifier NAC circuits.

4. Total the results of Steps 1 through 3.

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, a main “AUTOMATIC/MANUAL” switch, an “ALL-CALL ON/OFF” switch, two “Zone” select switches, and “NORMAL”, “TROUBLE”, Zone ”SELECT”, Zone “ALARM” and an all-call “SELECT” LEDs. Opening the enclosure door accesses the operator’s console. See Figure 5-1 on Page 5-3 for front panel layout.

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 returns 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”.

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” push button, a “TROUBLE ACKNOWLEDGE” push-button switch, a “MANUAL/AUTOMATIC” switch, an “ALL-CALL” switch, “ZONE 1”, and “ZONE 2” switches. 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 console instructions located on the dead front panel and are shown in Figure 5-1 on Page 5-3.

The “TROUBLE” and “NORMAL” LEDs identify to the operator the condition of the SAFEPATH® Panel. The 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 “MANUAL/AUTOMATIC” switch has two positions, manual (down) and automatic (up). When the “MANUAL/AUTOMATIC” toggle switch is in the automatic position, pre-recorded messages may be selected to play on individual circuits via dry contact inputs. When the “MANUAL/AUTOMATIC” switch is in the manual position, pre-recorded messages will not play, the visual notification appliances are energized, and the evacuation tone sounds on all circuits.

NOTE: When a dry contact closure occurs on any programmed input (IN1 through IN8), the

“ALL CALL”, “ZONE 1”, and “ZONE 2” switches have no control over the output unless the live microphone is used. Live microphone is the highest priority, messaging source and overrides dry contact inputs.

The “ALL-CALL” switch overrides “ZONE 1” and “ZONE 2” switch positions allowing audible signals to be heard regardless of the position of these switches.

The “ZONE 1” and “ZONE 2” on/off switches are used to select zones for live audible from the microphone. When a zone is switched “ON” the respective strobe circuit is also energized.

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 9-4 on Page 9-8 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.

5. Remove the optional Output Channel Module if the message files require only channel one.

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 Section 7-1 - SAFEPATH

Module Replacement Procedure on Page 7-14.

Procedure O

On the DCDC Module, the green NORMAL LED is “OFF”, the yellow TROUBLE LED is “ON”, D12 “ON”, D11 “OFF”, D10 “OFF”, and the MDX-2 SYSTEM NORMAL LED is “OFF”, SYSTEM TROUBLE LED is “ON”, and the TROUBLE LED flashes a “4-blink” pattern, 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.

7-13

Page 72

3. The optional Output Channel Module for channel two is not installed or is improperly installed.

The number of output channels installed must agree with the number of output channels

used in

the Programmed Message Kit (PMK). The Standard Message Kit (SMK) is always programmed for single channel output.

4. Failed audio channel on Series MDX-2 or an optional Output Channel Module.

If the error occurs while playing a file, the error was due to one of the first three possible causes. If the error occurs immediately after turning on power to the Series MDX-2, the error was due to the last possible cause.

If the error was due to the first or second 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.

2. Verify that the optional Output Channel Module is installed properly.

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 or Output Channel Module (MDV-OCM) and these components if defective shall be replaced immediately following Section 7-1 - SAFEPATH

Module

Replacement Procedure on Page 7-14.

Section 9-2 - Dual-Circuit System Mother Board (DCMB)

Wheelock, Inc. Part Number: 107372 The Dual-Circuit System Mother board (DCMB) provides all signal handling capabilities between

the DCDC and the amplifier modules, terminal blocks for output wiring, and connectors for handling signals between the DCDC and the digital voice module.

The DCMB is illustrated in Figure 9-2 on Page 9-4 Up to two amplifier modules may be connected to the DCMB. The amplifier modules may be

installed in any order in slots 1 and 2. Installing an amplifier module in slot 1 and 2 will result in the module’s output appearing in the correspondingly numbered terminal block (labeled “Zone 1” and “Zone 2”). For example, when an amplifier module is installed in slot 1, the amplifier module’s output appears at the terminal block labeled “Zone 1”.

Up to 2 channels from the Digital Voice Module (MDX-2) may be connected to the DCMB. The digital voice module is inserted into J5. The digital voice module channel will play through Zone 1 and Zone 2 if amplifier modules are installed.

IN1 through IN8 are the dry contact inputs used to trigger the automatic alarm circuits. With the MDX-2 Module installed, IN1 through IN8 provide access to as many as 8 programmed messages on the MDX-2.

If the MDX-2 is not used and the Shunt PCB is used, IN1 initiates Zone 1 and IN2 initiates Zone

2. IN3 through IN8 are not used. 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 24 VDC, 0.100 Amps that is non-supervised.

Section 9-3 - Dual-Circuit Control Module (DCDC)

Wheelock, Inc. Part Number: 107373 The Dual-Circuit Control Module (DCDC) provides all of the control capabilities for the

SAFEPATH

Circuit Power Supply (DCPS), and amplifier modules (SAA-40S, SAA-80S/SE, and SALL-15S) for proper operation. The microphone is supervised for connection.

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

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

The amplifier modules are supervised for two failure conditions: field wiring trouble conditions and amplifier audio output trouble conditions. The controller module 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.

If at any time a trouble condition is detected, the controller module will energize the internal audible and the external trouble audible circuit transfer the Form C trouble contact to the trouble position, turn off the “NORMAL” indicator, and turn on the “TROUBLE” indicator.

Synchronized signal for the Strobe NAC circuits can be energized by turning ON DIP switch SS. This will cause the Wheelock Synchronized Strobes to flash at the same time.

Other controls from the DIP Switches are, Remote Microphone ON/OFF (RM), and selection of supervisory tone from the built in tone generator (T1, T2, T3).

There are two 0.5A fuses on the printed circuit board. F1 is the fuse for Remote Microphone power, and F2 is the fuse for the external trouble audible. See Figure 9-3 on Page 9-6 for fuse location.

Section 9-4 - Digital Voice Module (MDX-2)

Wheelock, Inc. Part Number: 105094 The Digital Voice Module (MDX-2) is a plug-in module that provides playback capability of pre-

recorded messages. The MDX-2, when activated, provides a pre-recorded tone and/or message to the Dual-Circuit SAFEPATH audio appliances.

Panel which then broadcasts it through the amplifiers and to the

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 9-4 on Page 9-8shows 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. Jumper wires are in place on the MDX-2 so the same message will play on both channels. The Programmed Message Kit (PMK) is tailor made to the customer’s desires including separate messages on the two channels. The location of these kits are shown in Figure 9-4 on Page 9-8

The MDX-2 has a maximum of two line-level outputs that can play two different messages, one to each amplifier, simultaneously. This is done by installing an Output Channel Module (AM-MDVOCM), Wheelock, Inc. Part Number 105097 on the MDX-2 Module.

The MDX-2 for the Dual-Circuit SAFEPATH® Panel is configured for the same message to be transmitted on both amplifier modules. This is done with the jumper wires in the upper right hand corner shown in Figure 9-4 on Page 9-8.

The Standard Message Kit (SMK) has a variety of configurations. Consult the current Wheelock, Inc. Catalog for the up to date configurations.

Section 9-6 - SAA-40S (Supervised Audio System Amplifier/Signal Circuit

Module, 40 Watts)

Wheelock, Inc. Part Number: 105493 The SAA-40S is a supervised audio system amplifier/strobe circuit module. It is capable of

providing 40 watts of audio amplification and a 24V, 2.0 Amp strobe NAC circuit for the

SAFEPATH

amplifier contains a switch mode power supply, a linear amplifier, and supervision circuitry. The switch mode 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 board can be field configured for either 25V or 70.7V output. The configuration is done using a two-position slide switch (S1) on the printed circuit board. The down position configures the amplifier for a 25V output and the up position configures the amplifier for a 70.7V output. See Figure 9-6 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 printed circuit board. See Figure 9-6 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 9-6 on Page 9-11 for fuse locations.

amplification for the SAFEPATH

70.7V audio output. The SAA-80SE (Export version) has only a 100V audio output. The amplifier contains a switch mode power supply, a linear amplifier, and supervision circuitry.

The switch mode 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 80 watts output. The supervision circuit monitors field speaker wiring integrity, field strobe wiring integrity, and amplifier functionality.

The board of the SAA-80S can be field configured for either 25V or 70.7V output. The configuration is done using a two-position slide switch (S1) on the printed circuit board. The down position configures the amplifier to have a 25V audio output and in the up position configures the amplifier to have a 70.7V audio output. See Figure 9-7 on Page 9-13for switch location.

The board of the SAA-80SE is configured for a 100V output only. The two-position slide switch is removed.
