SYSTEM SENSOR
LOW PROFILE, IONIZATION
PLUG-IN SMOKE DETECTOR
DESCRIPTION
The System Sensor 1151 low profile ionization type smoke
detectors are specifically designed to meet the performance
requirements of fire detection/alarm systems. The 1151 ion-
ization detector uses a state-of-the-art, dual unipolar sensing
chamber. The detector is designed to provide open area de-
tection and, when installed in a two-wire base, is compatible
with FCI fire alarm control panels. The detector’s operation
and sensitivity can be tested in place.
The 1151 detector is of plug-in construction and plugs into
the same base as the System Sensor 2151photoelectronic
smoke detector, making both models interchangeable. Bases
are available for two-wire, four-wire, 120 VAC four-wire op-
eration and also with an audible sounder.
Two visible LEDs on each detector flash 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 1151 detector is Listed for use inside ducts up to a ve-
locity of 500 FPM.
Functional testing is performed by placing a test magnet
against the cover. The LED on the detector should light
within 30 seconds.
Field metering of detector sensitivity may be performed
with the aid of a voltmeter and Test Kit, MOD 400R.
