5.Apply power to the control unit to activate the SLC.
1.Before testing, inform the proper authorities that the system is undergoing maintenance and will temporarily be put out of service. Disable the system to prevent unwanted alarms.
2.Make sure the indicator LED on the detector’s surface is flashing. Failure to flash indicates a non-functioning detector or a faulty wiring. Check the wiring and remount the detector.
3.Go/No Go Field Test: Use the aerosol, Solo A4. The LED on FW511 should latch steady-on and the system should go into alarm.
4.Once the testing is completed, set the system back to normal operation and inform proper authorities.
The detector needs to be tested on a regular basis. Refer to the Testing section for more information about the procedure. The detector has an automatic-drift-compensation feature to provide accurate-sensitivity detection. When the drift is out of range, the “Device _GeneralTrbl” trouble will be displayed on the FACP, which means the sensitivity may be outside the limits and the detector needs cleaning.
1.Before cleaning, notify the proper authorities that the system is undergoing maintenance and will be temporarily out of service.
2.Disable the system to prevent unwanted alarms.
3.Remove the detector to be cleaned from the system.
4.Remove the detector cover and the maze cover.
5.Use a vacuum cleaner or compressed air to remove dust and debris from the maze.
6.Reinstall the detector.
7.Test the detector as described in the Testing section.
8.Notify the proper authorities that the system is back on line.
Figure 4. Cleaning
Return the detector for reparation if it fails to flash or alarm during testing. Do not disassemble the detector without permission.
