Description

The Honeywell Morley MI-DMMIE Single Input Module is engineered to maintain safety integrity and deliver precise input monitoring across commercial, industrial, and multi-tenant life-safety installations. Designed to connect directly to the Morley-IAS addressable communication loop, this compact module monitors the status of external non-addressable contact devices—such as flow switches, tamper switches, pressure switches, gas detectors, and third-party conventional panels—transmitting their status back to the main control panel. Its ultra-compact form factor allows direct installation inside device backboxes or junction enclosures. Equipped with onboard short-circuit loop isolation, mechanical rotary decade addressing switches, and a tri-color status LED, the MI-DMMIE ensures robust fault detection and full compliance with EN 54 safety standards.

Features

Compact micro-module housing enables effortless mounting directly inside third-party equipment enclosures and junction boxes
Supervised input line continuously monitors field wiring for open-circuit and short-circuit fault conditions using EOL resistors
Integrated short-circuit loop isolator safeguards addressable signaling line integrity during field wiring faults
Mechanical rotary decade switches enable fast, tool-free address configuration directly on the unit
Loop-powered operation eliminates the need for external power supplies, simplifying field installation and wiring loops
