Description

The System Sensor 2151 low profile photoelectronic
smoke detector is specifically designed to meet the perfor-
mance requirements of the fire detection/alarm systems.
The 2151 detector uses a state-of-the-art optical sensing
chamber and is designed so that if the LED fails, it will not
cause an alarm. The detector is designed to provide open
area detection, and when installed in a two-wire base, is
compatible with the Gamewell-FCI fire alarm control pan-
els. The detector's operation and sensitivity can be tested
in place.
The 2151 detector is designed with plug-in construction
and plugs into the same base as the 1151 ionization
smoke detector, making both models interchangeable.
Bases are available for the following types of operation.
• two-wire • 120 VAC four-wire
• four-wire • an audible sounder
Two visible LEDs on each detector flash approximately
every ten seconds indicating that the 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 2151 is UL® Listed for mounting inside ducts up to a
velocity of 3.000 FPM.
To perform functional testing, place a test magnet against
the cover. The LED on the detector should light within 30
seconds.
To perform the field metering of the detector sensitivity, use
a voltmeter and Test Kit. Part Number. MOD 400R.
