Apollo 45681-284APO Isolating Base

Apollo XP95 Isolating Base (Part No. 45681-284APO)

The Apollo XP95 Isolating Base (45681-284APO) helps maintain the integrity of addressable fire alarm systems by automatically detecting and isolating short-circuit faults on loops and spurs. Designed for use with Apollo XP95 devices, the isolating base is loop-powered, polarity-sensitive, and accepts the XPERT addressing card for the configuration of the associated detector.

When a short circuit occurs, the base immediately isolates the affected section of the circuit, helping to minimise disruption to the rest of the fire detection system. At the same time, the detector connected to the 45681-284APO remains operational, ensuring continued fire detection protection. Once the fault has been cleared, the isolating base automatically restores both power and communications to the affected section without requiring manual intervention.

A high-brightness yellow LED provides a clear visual indication of isolation status, making fault identification quicker and easier for maintenance personnel.
