CPD-7051
IONIZATION SMOKE DETECTOR
DESCRIPTION
The CPD-7051 dual chamber ionization smoke detector
senses both visible and invisible products of combustion and
is designed for 2-wire and 4-wire system operation. The 360^o
smoke entry characteristic permits maximum smoke
response from any direction.
To assure that the detector is functioning, an LED pulses
approximately every 4 seconds to allow for visual
supervision of the detector. Under alarm condition, the LED
lights constantly at full brilliance. An optional base is
available to provide a remote LED function.
A unique gated output circuit design provides improved
stability and transient suppression. Special signal processing
techniques verify the presence of smoke before the detector
will alarm.
Installation of the detector is easy and quick because of
non-polarized connections. The detector head is fixed to the
base by a twist-lock action.
Both functional and sensitivity testing of the device may be
accomplished by means of a test magnet. This simulates the
effect of smoke (approximately 1.3 % per foot obscuration)
entering the chamber.
In addition, the actual sensitivity of the detector may be
measured in direct readout of percent per foot obscuration
with a sensitivity tester and standard voltmeter without the
necessity of removing the detector.
An insect screen protecting the chamber is used to avoid
potential nuisance alarms.
CPD-7051 ionization detectors may be inter-changed with
PSD-7155 or PSD-7156 photoelectric detectors. Optional
bases are available for remote test, indication, 4-wire
operation and/or control functions. See Table 1. In addition,
an MA-001 adapter is available to enable the CPD-7051 to
mount in existing CPD series bases.
