Apollo XP95 Intelligent Isolator
£16.99 (inc VAT: £20.39)
Summary
The Apollo Isolator (Part No. 55000-720) is a critical protection device designed to maintain fire detection system integrity during short-circuit faults. Installed at strategic intervals along the detection loop, the isolator ensures that in the event of a short circuit, only the affected section between isolators is disabled, keeping the remainder of the system fully operational.
Utilising patented technology, the isolator automatically detects wiring short-circuits and isolates the faulty section. When the fault is cleared, power and data communication are automatically restored without manual intervention. The device is compatible with Apollo’s XP95, Discovery and CoreProtocol addressable fire detection systems, and must be used with the dedicated Isolator Base (Part No. 45681-211).
With approval from CPR, LPCB and VdS, the isolator meets stringent European standards and offers reliable performance across a wide operating temperature range of -30°C to +80°C.

FAQ
What is the purpose of an isolator in a fire detection system?
An isolator protects the integrity of your fire detection loop by ensuring that if a short circuit occurs, only the section between isolators is affected. This means the rest of your fire detection system remains fully operational, maintaining critical life safety protection throughout the building.
How many detectors can be installed between isolators?
Up to 20 detectors or equivalent devices may be installed between isolators. This allows for flexible system design whilst maintaining adequate short-circuit protection across the detection loop.
Does the isolator require manual reset after a fault?
No, the isolator features automatic de-isolation. When the short circuit is removed, the isolator automatically restores power and data communication to the previously isolated section without any manual intervention required.
Which fire detection systems is the isolator compatible with?
The Apollo Isolator is compatible with XP95, Discovery and CoreProtocol addressable fire detection systems. This provides compatibility across Apollo’s full range of modern addressable fire detection protocols.
Can the isolator be used with a standard addressable base?
No, the isolator can only be used with the dedicated Isolator Base (Part No. 45681-211) and will not fit standard addressable bases. This ensures proper electrical isolation functionality and maintains system integrity.
What approvals does the isolator hold?
The isolator holds CPR (Construction Products Regulation), LPCB and VdS approvals, meeting stringent European standards for fire detection equipment. It also complies with EMC Directive 2014/30/EU and Construction Products Regulation 305/2011/EU.
