The System Sensor 1451 ionization type smoke detectors
are specifically designed to meet the performance require-
ments of fire detection/alarm systems. The 1451 ioniza-
tion detector uses a state-of-the-art, dual unipolar sensing
chamber. The detector is designed to provide open area
detection and when installed in a two-wire base is com-
patible with FCI fire alarm control panels. The detectors
operation and sensitivity can be tested in place.
The 1451 detector is of plug-in construction and plugs into
the same base as the 2451 Series photoelectronic smoke
detectors, making both models interchangeable. Bases
are available for two-wire, four-wire, and 120 VAC four-
wire operation.
Two visible LEDs on each detector flash approximately
every ten seconds indicating that power is being applied
to the detector. The LEDs light steadily when the detector
is in alarm. A remote LED annunciator is available as an
optional accessory.
The 1451 detector is Listed for use inside ducts up to a
velocity of 1,200 FPM.
Sensitivity testing is performed by placing a test magnet
against the cover. The LED on the detector should light
within 5 seconds.
Field metering of detector sensitivity may be performed
with the aid of a voltmeter and Test Kit, MOD 400R.
