The A45E-2 is an addressable input interface unit specifically engineered for installation inside the enclosures of fire detection ancillary equipment. Connecting directly to the ZP loop wiring, this unit holds its own unique system address, allowing it to relay signals from external equipment straight into the fire alarm system. Once received, these input signals are fully displayed on the main control panel and can be programmed to trigger any designated system output.

Enhanced System Integrity

By routing the primary loop wiring directly to the interface and positioning the unit immediately adjacent to the monitored equipment, overall system integrity is significantly improved. This localized installation strategy removes the risks associated with long, vulnerable spur wiring between equipment terminals and the fire alarm system interface.
