Installation
NOTE: All wiring must conform to applicable local codes,
ordinances, and regulations.
NOTE: Verify that all detector bases are installed, that the
initiating-device circuits have been tested, and
that the wiring is correct. (Refer to detector base
manual for testing procedure.)
Remove power from initiating-device circuits before in-
stalling detectors.
1. Install detectors:
a. Place the detector into the detector base.
b. Turn the detector clockwise until the detector drops
into place.
c. Continue turning detector clockwise to lock it in
place.
2. Tamper Resistance: The detector bases can be made
tamper resistant. When capability is enabled, detectors
cannot be removed from the base without the use of a
tool. See the detector base installation manual of the
detector base for details in using this capability.
3. After all detectors have been installed, apply power to
the control unit.
4. Test the detector using the magnet as described under
TESTING.
5. Reset the detector at the system control panel.
6. Notify the proper authorities that the system is back on
line.

Dust covers are an effective way to limit the entry of dust
into smoke detector sensing chambers. However, they
may not completely prevent airborne dust particles from
entering the detector. Therefore, System Sensor recom-
mends the removal of detectors before beginning con-
struction or other dust producing activity.
Be sure to remove the dust covers from any sensors that
were left in place during construction as part of returning
the system to service.
Testing
Before testing, notify the proper authorities that the
smoke detector system is undergoing maintenance and
will temporarily be out of service. Disable the zone or
system undergoing maintenance to prevent unwanted
alarms. Detectors must be tested after installation and as
part of periodic maintenance. Test the 2151A as follows:
NOTE: Before testing the detector, check to ensure the
the LEDs blink. If they do not, the detector has
lost power (check the wiring) or it is defective
(return it for repair).
A. Test Magnet (System Sensor model no. M02-04-01)
1. Place the magnet against the cover in the location
designated by the raised mark to activate the test
feature (see Figure 1).
2. The LEDs should latch ON within 5 seconds indi-
cating alarm and annunciating the panel.
