CURRENT - 15mA maximum; 6mA minimum; NOTE: Output current is limited by 2.2Kohm resistor
with UL-listed, separately supplied power (4-wire) 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 trans-
mitter/receiver unit), the detector generates an alarm signal. Complete block-
age 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
