3. Using a flat head screwdriver, insert the blade into the slots and tilt to
release the latch and open the front cover (see figure 1).
4. Push in the locking clips located on each side of the reflector and remove
the reflector assembly (see figure 1).
Wall and Ceiling Mount
1. Remove the appropriate knockouts in the back plate.
2. Feed AC wires through the center hole into the back plate.
3. Mount and secure the back plate to the junction box. Ensure the gasket is
compressed tightly to the surface.
4. Make the proper connections according to model configuration:
For self-powered see figure 3.
For AC, AC/DC see figure 4.
5. Attach safety cable from housing to reflector assembly.
6. Connect battery connector to PCBA.
7. Reattach reflector assembly. Push in the locking clips located on each side
of the reflector and snap in reflector assembly (see figure 1).
