Apollo 55000-720APO Short Circuit Isolator
Part no.
The Apollo 55000-720APO is a short circuit isolator. The Apollo 55000-720APO is placed at intervals on the loop and ensures that, in case of a short circuit, only the section between the isolators will be affected.

Apollo Short Circuit Isolator (Part No. 55000-720APO)
The Apollo Short Circuit Isolator (55000-720APO) protects addressable fire alarm loops by automatically detecting and isolating sections affected by a short circuit. By installing isolators at strategic points around the loop, system designers can limit the impact of wiring faults and ensure that devices outside the affected section continue to operate normally.
When a short circuit occurs, the 55000-720APO immediately isolates the faulted section, helping to maintain communication and operation across the rest of the fire alarm system. As a result, disruption is kept to a minimum and overall system resilience is significantly improved.
Once engineers clear the fault, the isolator automatically restores both power and data to the previously isolated section without requiring any manual reset. This not only reduces maintenance time but also helps return the system to full operation more quickly.
Furthermore, the 55000-720APO is designed exclusively for use with an Apollo Isolator Base, ensuring reliable fault isolation and loop protection. However, it is not compatible with standard Apollo addressable mounting bases.
Key Features
- Automatically isolates short-circuit faults on the loop
