The CMX module can control 2 amps of resistive load (on electronic devices)
or 1 amp of inductive load (on mechanical bells and horns). If more than one
CMX Notification Appliance Circuit is provided, install the power supervision
relay after the last CMX. Refer to Device Compatibility Document 15378 for
compatible notification appliances and relays.
