D8 power distribution modules provide 8 protected DC outputs for use by a lifesafety system. When used in a single voltage system, each individual voltage output zone may be programmed for a continuous output or to respond to a fire alarm interface for control of egress locks. When used in a dual voltage system, each individual voltage output zone may be programmed for a continuous voltage of either voltage or, to respond to a fire alarm interface for control of egress locks at one of the two system voltages. F8 power distribution modules expand on the D8 capability by adding failsafe, failsecure, and FAI programming to each of the 8 voltage outputs as well as selection of either voltage in a dual voltage system, providing six programming choices per zone. Both the D8 and F8 modules may be used for lock control or power distribution in an access control system and for door holder power in a fire system.
