Sensitivity Testing
NOTE: Before testing, notify the proper authorities that the
smoke detector system is undergoing maintenance,
and therefore the system will be temporarily out of
service. Disable the zone or system undergoing main-
tenance to prevent unwanted alarms.
Detectors must be tested after installation and following
periodic maintenance. The sensitivity of the BEAM200A/
BEAM200SA may be tested as follows:
NOTE: Before testing the detector, check for the presence of
the flashing green LED at the receiver, making sure
not to disturb or block the beam. If it does not flash
and the detector is not in trouble or alarm, power has
been lost to the detector (check the wiring).
A. Calibrated Test Filter
The sensitivity of the detector can be tested using an
opaque material to cover the reflector by an amount indi-
cated by the graduated scale on the reflector. (Due to the
high optical efficiency of the reflector the selection of the
opaque material used to block the reflector is not critical.
Acceptable materials include, but aren’t limited to, this
manual or the cardboard packaging inserts.)
Refer to Figure 14 for this procedure.
1. Verify the sensitivity setting of the detector in % obscura-
tion. See the Sensitivity Selection section of this manual for
sensitivity determination if sensitivity is unknown.
2. Place the blocking material over the reflector, lining it up
with the graduated marks that are 10 less than the detec-
tor’s setting in % obscuration. The detector should not
alarm or fault. Keep the material in place for a minimum of
1 minute.
3. Place the blocking material over the reflector lining it up
with the graduated marks that are 10 more than the detec-
tors setting in % obscuration. The detector should enter
alarm within 1 minute.

4. The detector can be reset with the reset switch on the
detector unit or remote reset.
5. Notify the proper authorities that the system is back on
line.
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.
Note: For the BEAM200SA the external power supply must be
connected for the test switch to work.
