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.

Installation
Place the detector into the detector base. Turn the detec-
tor clockwise until the detector locks into place.
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. Install the detector. To remove
the detector from the base when using the tamper-proof
feature, insert the blade of a small screwdriver into the
hole on the side of the base and push the plastic lever
away from the detector head. This will allow the detector
to be rotated counterclockwise for removal. NOTE: The
decorative ring must be removed in order to remove the
head when using the tamper-proof feature.
The tamper-proof feature may be defeated permanently
by breaking the plastic lever off the base.
Note: The number of two-wire smoke detectors which can
be accommodated per zone varies with different control
panels. Consult the control panel instruction manual to
determine the capacity.
Refer to NFPA 72, Chapter 5-3, “Smoke Sensing Fire
Detectors” for spacing, location of detectors and other
guidelines.
Testing
Detectors may be tested in the following ways:
•Place a test magnet against the detector as directed in
the installation instructions. The detector should go into
alarm within 30 seconds.
•Field metering of detector sensitivity may be per-
formed with the aid of a voltmeter and Test Kit,
MOD 400R.
For the complete procedure, refer to the Installation and
Maintenance instructions furnished with each detector.
Cleaning programs should be adapted to the individual
environment in conformance with NFPA Standard 72. We
recommend at least an annual cleaning of the unit. The
detector screen and cover assembly can be removed,
revealing the sensing chamber. A vacuum cleaner can be
used to remove dust from the screen, cover and sensing
chamber. For the complete procedure, refer to the Instal-
lation and Maintenance instructions furnished with each
detector.
