remove gong. Retain hardware and gong.

2. Pull bell lead wires through hole in insulator

(Figure 2).

3. Feed the power source wiring from electrical outlet

box through the metal mounting plate. Ensure that

the mounting plate is aligned with the word "TOP" at

the top and facing out and secure metal mounting

plate to electrical outlet box with appropriate

hardware (not supplied).

Break wire run to provide electrical supervision. Do NOT

loop bell lead wires around signal circuit wiring.

4. Using wire nuts (not supplied), connect wires to circuit

and push wires and connections down inside the

electrical box (Figures 3 and 5).

5. Mount insulator and bell body onto studs of metal

mounting plate (Figures 2 and 3). Secure using two

lockwashers and two nuts (supplied).

CAUTION

Break wire run to provide electrical supervision. Do NOT

loop bell lead wires around signal circuit wiring.

4. See Figure 4. Using wire nuts (not supplied), connect

wires to circuit. Push connected wires into bell through

entrance hole in bell body base, while mounting

insulator and bell body onto studs of metal mounting

plate. Secure the bell body onto the metal mounting

plate using two lockwashers and two nuts (supplied).

5. Align the tabs on the back of the gong with the grooves

in the bell body and secure with the screw and

lockwasher removed in step 1.
