FCI Home Appliances 2151 - Manual

DESCRIPTION
The System Sensor 2151 low profile photoelectronic
smoke detector is specifically designed to meet the perfor-
mance 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 detector’s operation and sensitiv-
ity 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, mak-
ing 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 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 ve-
locity 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.
