5.7 Testing
Procedures
After successful installation and alignment (see manufacturer’s specific alignment procedure), the
Optical Beam Smoke Detector will require testing for both Fire and Trouble conditions
5.7.1 Smoke
Test
Tacking into account the sensitivity threshold set during installation, the Optical Beam Smoke
Detector can be smoke tested by progressively obscuring approximately half of the receiver optics
(for the projected type Optical Beam Detector) or half the Reflector (for the Reflected type) with non-
reflective material
The Transmitter optics must remain uncovered during the smoke test.
The Optical Beam Smoke Detector will indicate a fire within a defined time (typically 10 seconds) by
activating the fire indicator and closing the fire relay.
Once the environment is back to satisfactory level and if the Optical Beam Smoke Detector is not
latched, the device will automatically return in the condition prior to the fire, within a defined time. If
the Optical Beam Smoke Detector is latched. The device will have to be reset manually.
5.7.2 Fault
Test
The Receiver optics (for the Projected type Optical Beam Smoke Detector) and the Reflector (for the
Reflected type) should be covered totally. The Reflector should be covered with a non-reflective
material.
The Optical Beam Smoke Detector should indicate a Fault condition after a defined time by
activating the Fault indicator.
Once the obstruction has been removed, the Optical Beam Smoke Detector will automatically return
in the condition prior to the fault, within a defined time.
Note:
See manufacture’s product guide for all default, set up times and indicator characteristics
on both trouble and fire conditions
