Intelligent Addressable Fault Isolator Module

Intelligent Addressable Fault Isolator Module ISO-X

The Intelligent Addressable Fault Isolator Module ISO-X is a device commonly used in fire alarm systems to enhance reliability and fault tolerance. Its primary function is to isolate short circuits or other faults on the addressable loop, ensuring that the rest of the system remains operational. 

The Intelligent Addressable Fault Isolator Module ISO-X is an essential component in modern fire alarm systems, designed to enhance the system’s resilience by isolating and managing faults. This device plays a crucial role in maintaining the integrity of addressable fire alarm networks, ensuring that the detection and communication capabilities of the system remain intact even during electrical or wiring faults.

Fault Isolator Module ISO-X

The Fault Isolator Modules should be spaced between groups of sensors in a loop to protect the rest of the loop. Use to isolate short circuit problems within a section of a loop so that other sections can continue to operate normally. The ISO-X(A) supports a maximum of 25 devices in-between isolators, except when using relay bases or legacy IPX multisensory.

• Opens SLC loop automatically on detection of short, preventing the short from causing failure of the entire loop.
• Automatically resets on correction of short.
• EMS screws with clamping plates for ease of wiring.
• Mount on a standard junction box (4.0″/10.16 cm square) which is at least 2.125″/5.398 cm deep.
• Terminal screws are provided for “in and out” wiring.
• Installation instructions are provided with each module.
• Surface-mount box is available as an option.
