Honeywell Fire-Lite Alarms D350RPL Installation And Maintenance Instructions Manual

D350RPL INTELLIGENT PHOTOELECTRONIC DUCT SMOKE DETECTOR

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Before installing detectors, please thoroughly read the NEMA Guide for Proper Use of Smoke Detectors in Duct Applications, which

provides detailed information on detector spacing, placement, zoning, wiring, and special applications. Copies of this manual are avail-

able from NEMA (National Electrical Manufacturers Association, 2101 L Street NW, Washington, DC 20037). NFPA Standards 72 and

90A should also be referenced for detailed information.

NOTICE: This manual shall be left with the owner/user of this equipment.

IMPORTANT: This detector must be tested and maintained regularly following NFPA 72 requirements. The detector should be cleaned

at least once a year.

GENERAL DESCRIPTION

An HVAC system supplies conditioned air to virtually every area of a building. Smoke introduced into this air duct system is distributed

to the entire building. Smoke detectors designed for use in air duct systems are used to sense the presence of smoke in the duct.

The D350RPL air duct smoke detector is a photoelectric detector. This smoke detection method combines with an efficient housing

design that samples air passing through a duct and allows detection of a developing hazardous condition. When sufficient smoke is

sensed, an alarm signal is initiated at the fire control panel monitoring the detector, and appropriate action can be taken to shut off

fans, blowers and change over air handling systems, etc. This can prevent the distribution or it can isolate toxic smoke and fire gases

throughout the areas served by the duct system.

Two LEDs on each detector may illuminate, if programmed by the system control panel, to provide a local alarm indication. There

is also a remote alarm output for use with auxiliary devices. The D350RPL has remote test capability with the RTS451/RTS451KEY

Remote Test Station.

The D350RPL incorporates a cover tamper feature. When the cover is removed for more than 20 minutes, the unit loses communication

at the panel, a trouble is indicated at the panel and the alarm relay switches states thereby shutting down fans, dampers and blowers.

In the case when the sensor is removed or when there is no power to the unit, only a trouble is indicated at the panel (alarm relay

does not work any longer).
