Test Failure Checks
If the detector fails either the sensitivity or functional test, several steps
should be taken before returning the unit to determine if it is faulty, or simply
needs to be re-adjusted. 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.
It is imperative that at least 90% of the received light is from the reflector
alone, otherwise sensitivity cannot be assured.
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 procedure. If the detector still
fails the test it should be returned for repair.

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.
Functional Testing
For periodic maintenance functional testing, the detector can either be
tested using the Calibrated Test Filter method, by using the local test switch
on the transmitter receiver unit or remotely using the Remote Test Station.
The Remote Test Station,
RTS151KEY, can be used with the 6500R(S)E
beam smoke detector. The wiring diagram to connect the 6500R(S)E to
the key is displayed on page 2 of this manual.
.
The 6500RSE is equipped with an integral sensitivity test feature that
consists of a calibrated test filter attached to a servomotor 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. If
the correct level of signal reduction is received the detector will enter alarm.
If the proper level of signal reduction was not achieved, indicating that the
sensitivity of the detector is out of tolerance, the detector will enter the fault
condition.
Note:
This test should satisfy most local periodic maintenance and
testing requirements.
If the detector fails this test, refer to the Test Failure Checks described
above.
PAINTING
The outer aesthetic ring may be painted using enamel or acrylic paints either
by brush or spray.
Note: Never paint the flat lens surface of the outer housing.
Total obscuration can be converted to percent per metre assuming uniform
smoke density for the entire length of the beam. Graph 1 converts total
obscuration to percent per metre for all acceptable sensitivity settings.
SENSITIVITY TESTING
NOTES:
1. 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
maintenance to prevent unwanted alarms.
2. 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 fault or alarm, power has been
lost to the detector.
Detectors must be tested after installation and following periodic
maintenance. The sensitivity of the 6500RE may be tested as follows:
Calibrated Test Filter Method
The sensitivity of the detector can be tested using an opaque material
(such as this manual ) to cover the reflector by an amount indicated by the
graduated scale on the reflector, see Figure 10.
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
graduated marks that are 10 less than the detector 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 detector 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.
