The XP95A Isolator from Apollo is designed to protect and maintain the integrity of SLC circuits within addressable fire alarm systems. The device monitors the circuit and helps isolate the affected section in the event of a short circuit, reducing the impact of the fault on other devices connected to the loop.
Once the fault has been cleared, the isolator allows the affected section to be reconnected and normal system operation to be restored. This functionality helps improve fire alarm network reliability and minimize the impact of wiring faults on the overall system. The XP95A Isolator is suitable for use with compatible Apollo systems in commercial buildings, offices, hotels, public facilities, and industrial projects where reliable and continuous fire alarm system operation is required.
The XP95A Isolator from Apollo is a loop protection device designed to improve the reliability and operational integrity of addressable fire alarm systems. Its primary function is to protect the signaling line circuit by identifying and isolating sections affected by short-circuit conditions, helping prevent a single wiring fault from disrupting communication across a larger portion of the fire alarm system.
During normal operation, the isolator allows communication and power to pass through the circuit as required. If a short circuit occurs, the XP95A Isolator automatically isolates the affected section of the loop, allowing the remaining healthy sections and connected devices to continue operating wherever the system configuration permits. This helps maintain essential fire detection coverage during wiring faults.
Once the short-circuit condition has been removed, the isolator supports the restoration of the isolated section, allowing the circuit to return to normal operation. This automatic isolation and recovery capability reduces the impact of electrical faults and contributes to improved system availability.
The XP95A Isolator is particularly valuable in addressable fire alarm installations where a large number of detectors, manual call points, modules, and other field devices may share the same communication loop. Strategic use of isolators can help divide the loop into protected sections, limiting the number of devices that may be affected by a single short circuit.
The device is designed for integration with compatible Apollo addressable fire alarm equipment, providing a practical method of protecting loop communications without requiring complicated manual intervention when a short-circuit fault occurs. Its operation forms an important part of maintaining reliable communication between field devices and the fire alarm control panel.
Its compact design supports convenient installation as part of the fire alarm network while allowing system designers to incorporate short-circuit protection at appropriate points throughout the installation. This makes the isolator useful for both new fire alarm projects and system configurations where enhanced loop protection is required.
The XP95A Isolator is suitable for a wide range of applications, including commercial buildings, offices, hotels, educational and institutional facilities, public buildings, and industrial projects, particularly where continuity and reliability of the addressable fire alarm network are important considerations.
By providing automatic short-circuit isolation, protection of healthy loop sections, fault containment, and automatic restoration after the fault is cleared, the XP95A Isolator contributes to a more resilient and dependable addressable fire alarm system while helping minimize the operational impact of wiring faults.
