These adapters are specifically designed to interface with Network Door Controllers. They route power (PoE/PoE+) from a PoE switch or Midspan to the Network Door Controller and accommodate up to 2 Fail-Secure strikes or Fail-Safe mag locks. The receiver features a supervised Fire Alarm Disconnect which releases locking devices while maintaining power to the Network Door Controller. The Fire Alarm Interface feature allows multiple units to be interconnected enabling any or all to be affected from a single FACP trigger input.
