Beam Smoke Detector

I56-3433-001R

GENERAL DESCRIPTION

Model SK-Beam/SK-Beam-T is a long range projected beam smoke detector

designed to provide open area protection. It is to be used with UL-listed com-

patible 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 obscuration 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 de-

tector are compensated for by a microcontroller that continuously monitors

the signal strength and periodically updates the alarm and trouble thresh-

olds. When the self-compensation circuit reaches its limit, the detector gen-

erates 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 button is accessible by removing the outer paintable trim ring. The

yellow LED will blink in specific patterns to provide a diagnostic aid when
