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.
e. Continue rotating the sensor clockwise until it locks
in place.
