C4/C8 Power Controller Modules

Expand the number of system power outputs controlled by the access control system.
Program for fail-safe, fail-secure, dry contact or continuous voltage output


C4 and C8 power controller modules provide 4 or 8 relay controlled, protected outputs and 4 or 8 access control inputs. When used in a single voltage system, each individual output may be programmed for a continuous output or to respond to the input from the access control system. A fire alarm interface to over ride the access control system for control of egress locks is provided for each output. When used in a dual voltage system, each individual output zone may be programmed to operate with either of the two system voltages.
