These ProWire Unified Power wall mount models are dual voltage access power systems, precision wired for Mercury controllers. ProWire enables the specification and installation of standardized access power equipment across an enterprise for uniform operation, maintenance and servicing. The C8 or M8 control modules provide twenty four access control inputs capable of voltage or dry contact activation, and twenty four outputs programmable for failsafe / failsecure operation at either 12 or 24 VDC and controlled by the power supply fire alarm interface. The D8 modules provide forty auxiliary outputs. In dual voltage systems, each output is configurable for 12 or 24VDC operation. Fully managed models replace some or all D8 modules with M8 modules. ProWire Unified Power enclosures are painted steel with removable backplate, lock, keys and and tamper switch and come 100% factory tested – ready for final panel installation and field wire termination.
