If the detector fails this test several steps should be taken
to determine if the detector is faulty or simply needs to be
re-adjusted before returning the unit for repair. These steps
include:
1. Verify all wiring connections and appropriate power is
applied to the detector.
2. Verify that the optical line of sight is free from obstruc-
tions and reflective objects.
3. Apply the maintenance procedure in this manual.
Repeat the test procedure. If the detector still fails the
test procedure proceed with step 4.
4. Repeat the alignment procedure in this manual. If the
alignment procedure is successful repeat the test pro-
cedure. If the detector still fails the test it should be
returned.
Maintenance
NOTE:
Before cleaning the detector, notify the proper
authorities that the smoke detector system is
undergoing maintenance, and therefore the sys-
tem will be temporarily out of service. Disable the
zone or system undergoing maintenance to prevent
unwanted alarms.
1. Carefully clean the outer housing lens face. A damp soft
cloth with a mild soap may be used. Avoid products
with solvents or ammonia.
2. Carefully clean the reflector. A damp soft cloth with a
mild soap may be used. Avoid products with solvents or
ammonia.
3. Notify the proper authorities that the system is back on
line.
Painting
The outer aesthetic ring may be painted using a spray or
brush type paint of appropriate type. See specification sec-
tion of this manual for paint types.
NOTE:
Never paint the flat lens surface of the outer housing.
Special Note Regarding Smoke Detector Guards
Smoke detectors are not to be used with detector guards
unless the combination has been evaluated and found suit-
able for that purpose.
