产品介绍

功能特点

The FW841 conventional zone module is intended to allow Maple Armor intelligent fire alarm control panels to interface and monitor 2-wire conventional detectors in retrofit applications.

The initiating zone can support a mix of 2-wire conventional automatic detectors as well as normally open dry contact alarm initiating devices such as mechanical heat detectors and manual stations.

The Initiating Zone power can be derived either from the SLC loop or be provided by an external UL/ULC listed 24VDC power supply.

5. Combine the assembled unit to the base using the screws provided.

6.?Apply power to the control unit.


TESTING


1. Before testing, inform the proper authorities that the system is undergoing maintenance and will temporarily be put out of service. Disable the system to prevent unwanted alarms.

2.?Make sure the indicator LED on the detector’s surface is flashing (once every 3 seconds when powered by external 24VDC, or twice every 3 seconds when powered by SLC loop). Flashing 3 times every 3 seconds indicates the module is in trouble condition (for example missing EOLR). Failure to flash indicates a non-functioning module or a faulty wiring. Check the wiring and remount the module.

3. Trigger the input switch to activate a fire signal. The LED should turn to red steady on. Check the event occurrence displayed on LCD of the controller and verify.

4. Once the testing is completed, set the system back to normal operation and inform proper authorities.


MAINTENANCE


Return the module for repair if it fails to flash or alarm during testing. Do not disassemble the module without permission.
