Detector Board Replacement Instructions
1. Notify the proper authorities that the smoke detector system is undergoing
maintenance and that the detector will temporarily be out of service.
2. Turn off power to the duct smoke detector.
3. Remove the two detector board mounting screws.
Retain screws
for installation of new board.
4. Pull gently on the board to remove it from the detector housing.
5. Align the board mounting features, holes, and interconnect terminals
with the features on the duct smoke detector housing.
6. Push the board into place.
7. Secure the board with the two board mounting screws.
8. Perform the detector checks as outlined in sections 6.2.1 and 6.2.2.1 of the Installation and Maintenance
Instructions to ensure proper detector operation. The tests performed must include:
A. Visually check to see the green power LED blinks once every ten seconds, indicating power to the duct
smoke detector. If the green LED does not flash, the detector lacks power (check wiring, panel or power
supply), the detector board is missing (install), or the unit is defective (return for replacement).
B. Perform the magnet test to initiate an alarm condition. Reset the detector using the local reset button,
remote accessory or system control panel.
