The detector can be tested using the local test switch on
the transmitter/receiver unit or remotely using the remote
test station.
The remote test station, RTS451 or RTS451KEYA, can be used
with the BEAM200A/BEAM200SA beam smoke detector.
Follow instructions included with the test station for proper use.
See Figure 8 (Remote Test Station) for wiring diagram.
The BEAM200SA is equipped with an integral sensitivity test
feature that consists of a calibrated test filter attached to a servo
motor inside the detector optics. When a test is initiated using
the remote test station or local test switch the test filter is moved
in the pathway of the light beam. The on-board microproces-
sor then determines if the proper level of signal reduction is
received at the receiver. If the proper level of signal reduction
is received the detector will enter alarm. If the proper level of
signal reduction was not achieved, indicating that the sensitiv-
ity of the detector is out of tolerance, the detector will enter the
trouble condition.
Always perform a complete reflector blockage test as in step
4 of the Installation/Alignment procedure to insure that the
pathway between the detector and reflector is clear.
Note: For the BEAM200A this test does not satisfy the require-
ments of NFPA72 and/or ULC for periodic maintenance
and sensitivity verification of beam type detectors.
For the BEAM200SA this test in conjunction with the
complete reflector blockage test (see step 4 of the
Installation/Alignment procedure in this manual) does
satisfy the requirements of NFPA72 and/or ULC for peri-
odic maintenance and sensitivity verification of beam
type detectors.
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. 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 obstructions
and reflective objects.
3. Apply the maintenance procedure in this manual. Repeat
the test procedure. If the detector still fails the test proce-
dure proceed with step 4.
4. Repeat the alignment procedure in this manual. If the align-
ment procedure is successful repeat the test procedure.
If the detector still fails the test it should be returned for
repair.
Note: For the BEAM200SA, the external power supply must be
connected for the test switch to work.
Maintenance
NOTE: Before cleaning the detector, notify the proper
authorities that the smoke detector system is undergoing
maintenance, and therefore the system will be temporar-
ily 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.
