GENERAL DESCRIPTION
TAMPER-RESISTANCE
TESTING
CLEANING
- The device is photo electronic detector uses a state of-the-art optical sensing chamber.
- The alarm can be reset only by a momentary power interruption.
- Two LEDs on each detector provide local
360° visible alarm indication.
- They flash every 5 seconds indicating that power is applied and the detector is working properly.
- The LEDs latch on in alarm. LEDs will be off when a trouble condition exists indicating that the
detector sensitivity is outside the listed limit.
- This detector is designed to provide open area protection and to be used with most conventional
fire alarm control panel
- Before testing, notify the proper authorities that the smoke detector system is undergoing
maintenance and will temporarily be out of service.
- Disable the zone or system undergoing maintenance to prevent unwanted alarms.
- Detectors must be tested after installation and as part of periodic maintenance.
NOTE : Before testing the detector, check to ensure the LEDs blink.
- If they do not, the detector has lost power (check the wiring) , it is defective (return it for repair) ,
or the detector sensitivity is outside the listed limits.
The sensor can be tested in the following ways:
- Smoke Entry test: Aerosol Generator
(Gemini 501)
- The GEMINI model 501 aerosol generator can be used for smoke entry testing. Set the generator
to represent.
-
4%/ft
to
5%/ft
obscuration as described in the GEMINI 501 manual. Using the bowl shaped
applicator apply aerosol until the panel alarms.
- A sensor that fails any of these tests should be cleaned as described under
CLEANING
, and
retested. If the sensor fails after cleaning, it must be replaced.
The detector include a tamper-resistant capability that prevents their removal from the bracket
without the use of a tool.
Before removing the detector, notify the proper authorities that the smoke detector system is
undergoing maintenance and will be temporarily out of service. Disable the zone or system
undergoing maintenance to prevent unwanted alarms.
- Remove the sensor to be cleaned from the system.
- Vacuum the screen carefully without removing it. If further cleaning is required.
- Remove the chamber cover/screen assembly by pulling it straight out.
-
Use a vacuum cleaner or compressed air to remove dust and debris from the sensing chamber.
- Turn until it is firmly in place.
- Remove the sensor cover by pressing firmly on each of the four removal tabs that hold the cover
in place.
