GEnERAl DEScRiPTion
Fire•Lite Model BEAM355A/BEAM355SA is a long range projected beam
smoke detector designed to provide open area protection. It is to be used
with ULC-listed compatible control panels only. The detector consists of a
transmitter/receiver unit and a reflector. Smoke entering the area between the
transmitter/receiver and reflector causes a reduction in signal. When the ob-
scuration reaches alarm thresholds (chosen at the transmitter/receiver unit),
the detector generates an alarm signal. Complete blockage of the beam causes
a trouble signal. Slow changes in obscuration due to a build up of dirt or dust
on the lens of the detector are compensated for by a microcontroller that con-
tinuously monitors the signal strength and periodically updates the alarm and
trouble thresholds. When the self-compensation circuit reaches its limit, the
detector generates a trouble signal, indicating the need for service.

Three LEDs on the detector indicate the current status: a red LED for alarm, a
yellow LED for trouble, and a blinking green LED for standby operation. Note:
The panel controls the status of the red and green LEDs. The local reset but-
ton is accessible by removing the outer paintable trim ring. The yellow LED
will blink in specific patterns to provide a diagnostic aid when diagnosing the
cause of a trouble signal. It will also blink the amount of drift compensation
that has been used at the conclusion of the test. Trouble signals automati-
cally reset upon removing the cause of trouble. Red and yellow LEDs can be
remotely connected to the remote Alarm and Trouble outputs. These outputs
mimic the functions of the detector's red and yellow LEDs. In addition to these
indicators, there is a dual digital display that reads 00 to 99. This display is
used to indicate the signal strength of the beam in alignment mode and to
indicate the sensitivity setting of the detector in percent obscuration when
