Honeywell MorleyIAS Addressable Monitor Micromodule with 1 Input for Analogue Systems

Extended information about Honeywell MI-MM3E-S2 Addressable Monitor Micromodule with 1 Input for MorleyIAS Analogue Systems

Practical applications of the Honeywell MI-MM3E-S2 Addressable Monitor Micromodule

Example 1. Monitoring a door or external device with a volt-free contact:

In a MorleyIAS addressable fire detection installation, the MI-MM3E-S2 can be used to monitor an external device that provides a normally open contact. The module supervises the input circuit and communicates its condition to the fire alarm control panel, allowing the monitored point to be individually identified. This type of installation is particularly useful for integrating door contacts, flow switches or other auxiliary fire protection devices into the analogue loop.

Example 2. Adding a single monitored input to an existing MorleyIAS system:

When an existing installation only requires one additional supervised signal, the compact MI-MM3E-S2 provides a practical alternative to larger multi-input modules. It can be positioned close to the monitored equipment and assigned its own address using the integrated rotary selectors. This makes it suitable for system extensions, refurbishment projects and compatible replacement work where accurate identification of an individual external contact is required.
