Separate Power Supplies for Light and Sounder

In some applications it may be beneficial to control the light
independent of the sounder. If this is the case, separate power
supply wiring for each of the devices can be connected to the
terminal block. Required for the installation are supply wires of
the appropriate size (14 AWG [2.0 mm2] maximum thickness).
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.
To wire the light and sounder to separate power supplies:
1. Turn off power to the system.
2. Remove and retain the three #8 screws securing the upper
housing to the lower housing. Remove the upper housing.
3. Remove the factory field-wiring leads from the terminal block.
