The CMX Control Module is an addressable module that supervises and switches
power to a Notification Appliance Circuit (NAC). You can use CMXs for one of the
following applications:
• Switch 24 VDC NAC Power for NFPA Style Y (Class B) and NFPA Style Z
(Class A) circuits; or
• Control a dry contact relay (when configured as a Form-C control relay).
Figure 2-73 shows a CMX module configured for powering a 24 VDC NAC:

Ratings for the dry contacts on a CMX Form-C module are:
Resistive: 2 A @ 30 VDC
Inductive: 1 A @ 30 VDC (0.6pf)
Pilot Duty: 0.6 A @ 30 VDC (0.35pf)
The CMX module contains a magnetic test switch located on the front of the module.
Activate the test switch by placing a magnet over the CMX plastic cover. A test switch
activation causes a short circuit indication on a Style B or Style D NAC.
