Description
The System Sensor 2151 low profile photoelectronic
smoke detector is specifically designed to meet the per-
formance requirements of fire detection/alarm systems.
The 2151 detector uses a state-of-the-art optical sensing
chamber and is designed so that LED failure 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 FCI fire alarm control panels. The detec-
tor’s operation and sensitivity can be tested in place.
The 2151 detector is of plug-in construction and plugs into
the same base as the 1151 ionization smoke detector,
making both models interchangeable. Bases are available
for two-wire, four-wire, and 120 VAC four-wire operation,
and also with an audible sounder.
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 2151 is UL Listed for mounting inside ducts up to a
velocity of 3,000 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, Part No. MOD
400R.
