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.
CAUTION
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 enter-
ing the detector. Therefore, System Sensor recommends the
removal of detectors before beginning construction 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.
CAUTION
Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found
suitable for that purpose.
Testing
Before testing, notify the proper authorities that the smoke
detector system is undergoing maintenance and will tem-
porarily 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 2151 as follows:
NOTE: Before testing the detector, check to ensure 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 (p/n M02-04-01 or M02-09-00)
1. Place the magnet against the cover in the location
designated by the raised mark to activate the test fea-
ture (see Figure 1).
2. The LEDs should latch ON within 5 seconds indicat-
ing alarm and annunciating the panel.
B. Test Module ( MOD400R)
Use the MOD400R with a DMM or voltmeter to check
the detector sensitivity as described in the MOD400R
manual.
C. Aerosol Generator (Gemini 501)
Set the generator to represent 4% to 5%/ft. obscuration
as described in the Gemini 501 Manual. Using the bowl-
shaped applicator, apply aerosol until unit alarms.
Notify the proper authorities that the system is back on
line.
Detectors that fail these tests should be cleaned as
described under MAINTENANCE and retested. If the detec-
tors still fail these tests, they should be returned for repair.
Maintenance
It is recommended that the detector be removed from
its mounting base to facilitate cleaning. The detector is
cleaned as follows:
NOTE: Before removing the detector, notify the proper
authorities that the smoke detector system is
undergoing maintenance and will be temporarily
out of service. Disable the zone or system undergo-
ing maintenance to prevent unwanted alarms.
