Description

Morley Addressable Isolator Module (MI-DISO)

Overview

The Morley Addressable Isolator Module (MI-DISO) is a loop-powered, intelligent short circuit isolation device engineered to protect Morley-IAS analogue addressable fire alarm systems against wire-to-wire short circuits on the analogue addressable loop wiring. Manufactured by Morley-IAS — a trusted brand under Honeywell with decades of fire safety expertise — this module ensures that a single cable fault does not disable the entire detection loop, maintaining system integrity and life safety when it matters most.

Designed to be strategically placed between groups of sensors on the loop wiring, the MI-DISO automatically isolates faulty sections of the loop, allowing the remainder of the system to continue functioning uninterrupted. When a short circuit fault occurs, the two isolators located on either side of the fault automatically sense the voltage drop, open their switches, and remove the affected devices from the rest of the loop. Once the fault is cleared and line voltage rises above a fixed threshold, the isolator module automatically restores power to the isolated group of devices.

Whether you’re equipping a commercial building, an industrial facility, a hospital, or a residential complex, the Morley Addressable Isolator Module delivers the intelligence, reliability, and performance you need for robust fire protection with enhanced system resilience.
