2151

SYSTEM SENSOR

LOW PROFILE, PHOTOELECTRONIC,

PLUG-IN SMOKE DETECTOR

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.
