Mounting the modules
The M500-BK9 Module Mounting Bracket holds up to 9 M500 series intelligent addressable modules which
can be mounted in 2 layers. The first layer consists of 5 modules mounted to the bracket. The second layer
consists of 4 modules mounted to standoffs. The terminal blocks provide an accessible field wiring location
for 4 modules on the first layer. Refer to Figure 2.

If you are mounting 1 layer of modules
1. Mount up to 5 modules to the bracket using the included screws in the inner holes of the modules.
2. Mount the bracket to the backbox using either self-tapping screws or studs on the backbox.
If you are mounting 2 layers of modules
When all 9 modules are mounted, the 4 rightmost modules on the first layer are inaccessible. The terminal
blocks provide an accessible field wiring location for these 4 modules. Follow the instructions below.
1. Mount 5 modules to the bracket using the included standoffs in the inner holes of the modules.
2. Wire the 4 rightmost modules (the ones furthest to the right) to the terminal blocks.
With firephone modules, connect the wires from the EOL (conventional loop) side to the terminal blocks.
Figure 3 shows an example of 4 firephone modules wired to the terminal blocks.

3. Mount up to 4 modules to the standoffs using the included screws in the outer holes of the modules.
Refer to Figure 2.
4. Mount the bracket to the backbox using either self-tapping screws or studs on the backbox.
