in the bell body and secure with the screw and
lockwasher removed in step 1.
Surface Mounting (Figure 4)
1. Remove screw and lockwasher from front of gong and
remove gong. Retain hardware and gong.
2. Cut bell wire leads as needed and strip wire leads back
1/4".
3. Ensure that the mounting plate is aligned with the
word "TOP" at the top and facing out and secure metal
mounting plate to surface using screws appropriate
for the mounting surface (not supplied). Place
insulator over studs on mounting plate (Figure 2).
CAUTION
Break wire run to provide electrical supervision. Do NOT
loop bell lead wires around signal circuit wiring.
Installation
CAUTION
Do not apply power to bell until installation has been
completed.
Prior to starting installation, refer to Figure 1 for bell size.
The metal mounting plate supplied with these bells mounts
directly on the surface of any single or double gang 3"
octagon box, 4" octagon box or 4" square wall box or
their plaster cover (boxes and covers supplied by others).
For outdoor mounting, use Cat. No. 449 weatherproof box
(ordered separately) as shown in Figure 1.
Wall Box Mounting (Figure 3)
1. Remove screw and lockwasher from front of gong and
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).
CAUTION
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.
Applying Power
WARNING
This device will not operate without electrical power. As
fires frequently cause power interruptions, we suggest you
discuss further safeguards with your local fire protection
specialist.
1. Apply power to fire alarm or system control panel.
2. Initiate an alarm to activate bell and verify that it
sounds.
3. Reset panel to silence bell and return panel to
supervisory mode.
Maintenance
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).
CAUTION
Always disconnect all power before servicing or cleaning
bell.
Examine bell annually for accumulation of dirt and clean
when necessary.
5. Mount insulator and bell body onto studs of metal
mounting plate (Figures 2 and 3). Secure using two
lockwashers and two nuts (supplied).
