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 available from NEMA (National Electrical

Manufacturers Association, 2101 L Street NW, Washington, DC 20037). NFPA Standards 72 and 90A should also be referenced for detailed informa-

tion.

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 D350PL 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 D350PL has remote test capability with the RTS451/RTS451KEY Remote Test Station.

INSTALLATION AND MAINTENANCE INSTRUCTIONS

Figure 1: Exploded View Of Duct Smoke Detector Components

NOTE: For ducts over 1

⁄2 (0.46m) feet, longer sampling tubes must be ordered to complete the installation. They must be the correct length for the

width of the duct where they will be installed. See Table 1 on page 3 to determine the sampling tube required for different duct widths.

1. Complete duct smoke detector assembly with

sensor

2. Two #10 x 1

⁄4″ sheet metal mounting screws

3. Two sampling tube filters

4. One test magnet

5. Drilling template

6. Two foam gaskets

7. Four #6-self tapping mounting screws for the

sampling tube and optional exhaust tube

extension

8. One sampling tube end cap

9. One plastic sampling tube

10. One #8 self-tapping screw for plastic sampling

tube

NOTE: A detector sensor board DOES

NOT need to be ordered separately.
