Replacing the Sounder Installation and Maintenance Manual ■ Occasionally check for a reduction in the output of the sounder. If the sound pressure is reduced to an ineffective level, replace the sounder. SHOCK HAZARD—Do not connect the light to the system while the power is on. Failure to heed this warning may cause serious injury or death. Accessing the Sounder The sounder is located on the bottom of the upper housing (Figure 6 on page 14). To access the sounder: 1. Turn off power to the system. 2. Loosen the lens locking screw and twist the lens counterclockwise one-quarter turn. Remove the lens from the upper housing. 3. Loosen the screws on terminal block J9 on the PCBA and remove the black leads of the sounder. 4. The mounting holes permit only one orientation of the PCBA. Note or mark the orientation. 5. Use a flat-head screwdriver to carefully pry the PCBA from the three nylon standoffs and set the PCBA aside. 6. Remove the three #8 screws securing the upper housing to the lower housing and remove the upper housing. Replacing the Sounder and Reassembling the Light 1. Unscrew the sounder from the upper housing (Figure 5 on page 12). Be careful to not lose the three washers that space the sounder from the upper housing. 2. Place the washers on the threaded lug of the new sounder and hand-tighten the sounder. Model AV1-LED Lights 15
