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
detector are compensated for by a microcontroller that continuously monitors
16 to 230 Feet (5 to 70 m); 230 to 328 Feet (70 to 100 m) using optional accessory BEAMLRK

Level 3 = 40%
Level 4 = 50%
Level 5 = 30% to 50% (Acclimate)

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
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 sig-
