GENERAL DESCRIPTION
The model SDX-551/SDX-551TH photoelectronic sensor utilizes a state-of-the-art, optical sensing chamber. This sensor
is designed to provide open area protection, and to be used with compatible UL-listed NOTIFIER control panels only.
Suitable for use with panel Model AM2020, Loop Interface Board, LIB-200; compatibility ID:A; maximum number of sen-
sors per loop is 99. See 155-531, Revision A, for installation and wiring diagrams.
Two LEDs on each sensor light to provide a local 360° visibility of the sensor indication. The LEDs can be latched ON by
code command from the panel for an alarm indication. The LEDs can also be unlatched to the normal condition by code
command. Remote LED annunciator capability is available as an optional accessory (part no. RA400Z).
The SDX-551TH adds a thermal heat collector that alarms at a fixed temperature of 135° F.
