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.
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
entering the detector. Therefore, Edwards 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. De-
tectors must be tested after installation and as part of peri-
odic maintenance. Test EDW2151A 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 (CSENS-RDRA)
Use the CSENS-RDRA Sensitivity reader to measure
the sensitivity of the detectors. Please refer to the
CSENS-RDRA instruction manual for operating details.
B. Aerosol Generator (Gemini 501)
Set the generator to represent 4% to 5%/ft. obscura-
tion 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 de-
scribed under MAINTENANCE and retested. If the detec-
tors still fail these tests, they should be returned for repair.
Cleaning
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 undergoing maintenance to prevent unwanted
alarms.
