PSD-7155 SERIES
PHOTOELECTRIC SMOKE DETECTOR
DESCRIPTION
The PSD series photoelectric smoke detectors respond to a
broad spectrum of both flaming and smoldering fire conditions.
They incorporate state-of-the-art, solid-state, low-voltage
circuitry and are designed for 2-wire and 4-wire installation
with the proper base. High signal-to-noise ratio permits a
significant reduction in light baffling, thereby improving smoke
entry characteristics while reducing nuisance alarms.
Three separate detection identifications are required for alarm
confirmation. This three level detection sequence reduces
nuisance alarms. Each identification is made at two second
intervals. Digital storage of the previous identifications
provides positive and reliable detection.
Functional testing is accomplished by means of a test magnet.
This magnet test meets the requirement of the U.L. Sensitivity
Test Feature. In addition, the actual sensitivity of the detector
may be measured in direct percent per foot obscuration with a
sensitivity tester and standard voltmeter without the necessity
of removing the detector.
The companion model PSD-7156 includes a thermistor heat
detector with a 135^o F setpoint and is independent of smoke
detector circuitry.
The PSD photoelectric detectors may be interchanged with
Model CPD-7051 ionization detectors. Optional bases are
available for remote test, remote indication, 4-wire operation
and/or control functions. See Table I. In addition, an MA-001
adapter is available to enable the PSD-7155 and PSD-7156 to
mount in existing Model CPD series bases.
