Figure 4.7-2 Providing Power to Control Modules
Notification appliance power can be supplied to CMX Control Modules by any one of the supplies illustrated in
Figure 4.7-2. This power is unsupervised and must be connected to a Power Supervision Relay wired to a CMX
Control Module (refer to Figures 4.7-3 through 4.7-5) or dedicated MMX module using the "MTRB" type ID.
When a remote power supply is employed, it must also be supervised.
