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.

Mounting

The 2151 can be mounted on the following:

On a 4-inch square box with or without a plaster ring.
Minimum depth 1.5 inches.

On a 3.5-inch octagonal box. Minimum depth 1.5inches.

Installation

To install the detector, do the following:
1.

Place the detector into the detector base. 

2.

Turn the detector clockwise until the detector locks 
into place.

3.

To use the tamper-proof feature, break the smaller tab 
on the scribed line in the tamper proof tab located on 
the detector mounting bracket. 

4.

Install the detector.

Shows a 360° view angle of the alarm LEDs.

Compatible with Gamewell-FCI control panels.

Uses an audible sounder base (optional).

Supports the field metering of detector sensitivity.

Provides a removable insect screen and cover for field 
cleaning.
