Fire•Lite Model BEAM355/BEAM355S is a long range projected beam smoke
detector designed to provide open area protection. It is to be used with UL-
listed compatible control panels only. The detector consists of a transmitter/
receiver unit and a reflector. Smoke entering the area between the transmit-
ter/receiver and reflector causes a reduction in signal. When the obscuration
reaches alarm thresholds (chosen at the transmitter/receiver unit), the de-
tector 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
