– Adherence to the following will aid in problem-free installation with long-term reliability:

WARNING

fire alarm control panel. Disconnect all sources of power before servicing. Control unit and associated equipment may be damaged by removing and/or inserting cards, modules, or interconnecting cables while the unit is energized. Do not attempt to install, service, or operate this unit until this manual is read and understood.

CAUTION

ensure proper system operation, this product must be tested in accordance with NFPA 72-1993 Chapter 7 after any programming operation or change in site-specific software. Reacceptance testing is required after any change, addition or deletion of system components, or after any modification, repair or adjustment to system hardware or wiring.

All components, circuits, system operations or software functions known to be affected by a change must be 100% tested. In addition, to ensure that other operations are not inadvertently affected, at least 10% of initiating devices that are not directly affected by the change, up to a maximum of 50 devices must also be tested and proper system operation verified.

An automatic fire alarm system

detectors, heat detectors, manual pull stations, audible warning devices and a fire alarm control with remote notification capability can provide early warning of a developing fire. Such a system, howev er, does not assure protection against property damage or loss of life resulting from a fire.

Any fire alarm system may fail for a variety of reasons: Smoke detectors

detectors such as in chimneys, in walls, or roofs, or on the other side of closed doors. Smoke detectors also may not sense a fire on another level or floor of a building. A second floor detector , for example, may not sense a first floor or basement fire. Furthermore, all types of smoke detectors - both ionization and photoelectric types, have sensing limitations. No type of smoke detector can sense every kind of fire caused by carelessness and safety hazards like smoking in bed, violent explosions, escaping gas, improper storage of flammable materials, overloaded electrical circuits, children playing with matches, or arson.

IMPORTANT!

Although no system is completely immune from lightnin transients and interferences, proper grounding will reduce susceptibility. Overhead or outside aerial wiring is not recommende due to an increased susceptibility to nearby lightning strikes.

Optional Boards

The PDRP-1002/PDRP-1002E has mounting slots for two option boards. Any two of the three option modules may be installed.

Transmitter Module (4XTM - NOTIFIER)

The Transmitter Module provides a supervised output for local energy municipal box transmitter (for NFPA 72 Auxiliary Fire Alarm System) and alarm and trouble reverse polarity circuits (for NFPA 72 Remote Statio n Fi re Alarm System). Also included is a DISABLE switch and disable trouble LED.

As a jumper option, the alarm reverse polarity circuit will open on trouble if no alarm exists.

LED Interface Module (4XLM - NOTIFIER)

The LED Interface Module supports the RZA-4X Remote Annunciator module. Annu nciator wi ring is superv ised for open conditions by this module. The Annunciator Driver Module mounts to the main board, occupying on e of the two option connectors.

Transmitter Module (4XTM - NOTIFIER)

Zone Relay Module (4XZM - NOTIFIER)

The Zone Relay module provides Form-C contacts for the following:

As a jumper option, the first four relays described below can be made silenceable.

Optional Meters

Remote Annunciator (RZA-4X - NOTIFIER)

The Remote Annunciator mounts on a standard singlegang box, and provides LED indication of the same functions as the zone relay module. For example with DIP 1=ON and DIP 2=OFF:

• One Zone in Alarm (red)

• Two Zones in Alarm (red)

• Releasing Circuit 1 (red)

• Releasing Circuit 2 (red)

• System Trouble (yellow)

A Local Trouble Sounder and Silence Switch are also provided. All LED wiring is supervised for open conditions. Any open condition will cause the System Trouble LED to illuminate.

Note: The Remote Annunc iator requir es the use of an LED Interface m od ule (4XLM).

Voltage, Current Meters (4XMM - NOTIFIER)

The Meter Module provides a voltmeter to measure the voltage across the batteries and an ammeter to measure the charging current to the batteries. The meters are provided as an assembly that mounts to the lower lefthand corner of the cabinet.

2 System Operation

Tone Silence

Acknowledge alarms, troubles and supervisories. The panel has alarm and trouble resound with LED flash of new conditions. The flashing trouble LED(s) illuminate steadily on TONE SILENCE and the piezo sounder silences. A second trouble will resound the piezo. The piezo has three sounds for alarm, trouble, and supervisory. Trouble cond i tio ns are self- res to ring . Alar ms latch and require RESET to clear.

Alarm Silence

Acknowledge for alarms and supervisories. The ALARM SILENCE switch will silence the local piezo, change any flashing alarm LEDs to steady, and turn off the notification circuits (not the releasing circuits). The “ALARM SILENCED” LED will illuminate. Alarm silence is a latching function and requires a RESET to clear.

Alarm Activate

The ALARM A CTIVATE switch may be used to activate Notification Appliance Circuits. ALARM ACTIVATE also activates the System Alarm relay. ALARM Activate is a latching function. Pressing ALARM SILENCE silences the notification circuits and System Alarm Relay and lights the Alarm Silenced LED. Pressing RESET returns the system to normal.

System Reset

The RESET switch breaks power to all initiating circuits, 4-wire smoke power and option boards and will clear any activated output circuits. If any alarms or troubles still exist after reset, they will reacti vate th e panel. Holding RESET down will perform a LAMP TEST function and will activate the piezo sounder.

Output circuit #4 is used as an input for monitoring supervisory devices such as valve tamper switches (note that SW1 DIP switch #2 must be set “ON” -- see section “Setting Mode of Operation”) By setting Switch short circuit on this input (activation of a N.O. contact) will cause the supervisory LED to flash. The piezo sounder will generate a unique sound. TONE SILENCE will silence the piezo and cause the LED to illuminate steadily. Supervisory signals latch and require RESET to clear . An open circuit will be reported as a circuit trouble.

If a zone has been disabled, an alarm that occurs on that zone will flash the red zone LED, but not the p iez o or any output circuit.

If both power sources are removed from the system, all zones will be re-enabled upon restoration of power. Disable status will be lost .

The Zone Disable routine m akes use of the four panel switches as follows:

1. Press and hold in the TONE

SILENCE switch.

Last Event Recall

2. With the TONE SILENCE switch

held in, press (in sequence) the ALARM SILENCE switch, the ALARM ACTIVATE switch, and then the RESET switch.

3. The Zone 1 Alarm LED will flash.

4. To disable Zone 1, press the RESET switch. The Zone 1 yellow LED will light to

show that the zone is disabled.

Note: The RESET switch toggles disable status for the selected zone.

5. To select the next zone, press the ALARM SILENCE switch.

6. To select the previous zone, press the ALARM ACTIVATE switch.

7. When disable selections are complete, release the TONE SILENCE switch.

If any zone has been disabled, the trouble relay will activate and System Trouble LED will flash.

Last Event Recall allows the user to display the previous panel status. The last event recall uses the four panel switches as follows:

1. Press and hold in the TONE SILENCE switch.
