SEnSiTiviTy TESTinG

NOTE:

Before testing, notify the proper authorities that the smoke detector

system is undergoing maintenance, and therefore the system will be tempo-
rarily out of service. Disable the zone or system undergoing maintenance to
prevent unwanted alarms.
Detectors must be tested after installation and following periodic maintenance.
The sensitivity of the BEAM355/BEAM355S 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 indicated 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 in-
clude, 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 % obscuration. 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 gradu-

ated marks that are 10 less than the detector’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 gradu-

ated marks that are 10 more than the detectors 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 proce-

dure. If the detector still fails the test procedure proceed with step 4.

4. Repeat the alignment procedure in this manual. If the alignment proce-

dure is successful repeat the test procedure. If the detector still fails the
test it should be returned.

NOTE:

For the BEAM355S the external power supply must be connected

for the test switch to work.

B. Test Switch

The detector can be tested using the local test switch on the transmitter/re-
ceiver unit or remotely using the remote test station.

The remote test station can be used with the BEAM355/BEAM355S beam
smoke detector. Follow instructions included with the test station for proper
use. See Figure 8 (Remote Test Station) for wiring diagram.

The BEAM355S is equipped with an integral sensitivity test feature that con-
sists 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 micro-
processor 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, indi-
cating that the sensitivity 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 Instal-
lation/Alignment procedure to ensure that the pathway between the detector
and reflector is clear.

NOTE:

For the BEAM355 this test does not satisfy the requirements of

NFPA72 for periodic maintenance and sensitivity verification of beam type
detectors. For the BEAM355S this test in conjunction with the complete reflec-
tor blockage test (see step 4 of the Installation/Alignment procedure in this
manual) does satisfy the requirements of NFPA72 for periodic 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 proce-

dure. If the detector still fails the test procedure proceed with step 4.

4. Repeat the alignment procedure in this manual. If the alignment proce-

dure is successful repeat the test procedure. If the detector still fails the
test it should be returned for repair.

NOTE:

For the BEAM355S, 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 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 section 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 combina-
tion has been evaluated and found suitable for that purpose.
