Before Installing

Please thoroughly read Guide for Proper Use of System

Smoke Detectors (I56-407-XX), which provides detailed in-

formation on sensor spacing, placement, zoning, and spe-

cial applications. Copies of this manual are available from

System Sensor.

General Description

Models 1551B dual-chamber ionization intelligent sensors

utilize a state-of-the-art, unipolar sensing chamber. These

sensors are designed for use with duct housings DH500

and DH500AC/DC only, and to be used with compatible

control panels only. Connect sensors only to compatible

control units. (For installation in Canada, refer to CAN/

ULC-S524-M86, Standard for the Installation of Fire Alarm

Systems and CEC Part 1, Sec. 32.)

Two LED’s on each sensor light to provide a local 360° vis-

ibility of the sensor indication. The LED’s can be latched

on by code command from the panel for an alarm indica-

tion. The LED’s can also be unlatched to the normal condi-

tion by code command. Remote LED annunciator

capability is available as an optional accessory (Part No.

RA400).

Wiring Guide

Model 1551B can be used with any one of a variety of plug-

in bases. Therefore, connect all wiring following the

installation instructions provided with the base that was

selected for use with the 1551B. As Figure 1 indicates,

bases are equipped with screw terminals for all

appropriate connections.

NOTE: All wiring must conform to applicable local codes,

ordinances, and regulations.

NOTE: Verify that all sensor bases are installed and that

the wiring polarity is correct at each base.

WARNING

Remove power from the loop before installing sensors.

1. Install sensors:

a. Verify that the sensor type matches the type written

on the label on the base.

b. Set the sensor to the desired address and record it on

the label on the base.

c. Place the sensor into the sensor base.

d. Rotate the sensor clockwise until it drops into place.
