OPERATING INSTRUCTIONS
8.1 SCOPE
The following instructions are designed to obtain optimal performance from the detector over its life cycle.
CAUTION
Disconnect automatic extinguishing system actuator(s) from system before powering up
detector(s). Failure to do so may result in unwanted discharge.
8.2 POWER-UP/FUNCTIONAL TESTING
1. Apply power and wait approximately 60 seconds for the manual/automatic BIT (self-test) of the detector.
Note:
Applying power
initiates the following sequence: The LED will flash (4Hz) yellow. Manual/automatic BIT is executed; if successful then: The LED
will flash (1Hz) green.
2. Wiring Inspection: If an open detection circuit condition exists,a fault indication will appear on the CHECKFIRE control unit display
panel. Review your wiring.
3. The detector goes into its FAULT state when supply voltage drops below 16.5V. The detector status goes back to NORMAL when
the supply voltage is above 17.5V.
4. Detector Inspection: Visually inspect the viewing window of the detector. It should be clean and clear. The LED should flash (1 Hz)
green.
5. If any of the outputs or indications is different from the description in step 4, see paragraph 9.6 for troubleshooting.
8.3 SAFETY PRECAUTIONS
After powering-up, the detector requires minimal attention in order to function properly, but the following should be noted:
1. Follow the instructions in the manual and refer to the drawings and specifications issued by the manufacturer.
2. Do not expose the detector to radiation of any kind unless required for testing purposes.
3. Do not open the detector housing.
4. Disconnect external devices, such as automatic extinguishing systems, before carrying out any maintenance.
