It is to be used ULC-listed compatible control panels only. The detector consists of a unit and a reflector. Smoke entering the area between the and reflector causes a reduction in signal. When the ob- reaches alarm thresholds (chosen at the transmitter/receiver unit), detector generates an alarm signal. Complete blockage of the beam causes trouble signal. Slow changes in obscuration due to a build up of dirt or dust the lens of the detector are compensated for by a microcontroller that con- monitors the signal strength and periodically updates the alarm and thresholds. When the self-compensation circuit reaches its limit, the generates a trouble signal, indicating the need for service. LEDs on the detector indicate the current status: a red LED for alarm, a LED for trouble, and a blinking green LED for standby operation. Note: panel controls the status of the red and green LEDs. The local reset but- is accessible by removing the outer paintable trim ring. The yellow LED blink in specific patterns to provide a diagnostic aid when diagnosing the of a trouble signal. It will also blink the amount of drift compensation has been used at the conclusion of the test. Trouble signals automati- reset upon removing the cause of trouble. Red and yellow LEDs can be connected to the remote Alarm and Trouble outputs. These outputs the functions of the detector red and yellow LEDs. In addition to these there is a dual digital display that reads 00 to 99. This display is to indicate the signal strength of the beam in alignment mode and to the sensitivity setting of the detector in percent obscuration when
