Description
Morley Addressable Control Module
Overview
The Morley Addressable Control Module is a sophisticated, loop-powered remote switching and monitoring device engineered to seamlessly integrate with Morley-IAS analogue addressable fire alarm systems. Manufactured by Morley-IAS — a trusted brand under Honeywell with decades of expertise in fire safety — this module provides intelligent control over auxiliary devices such as sounders, strobes, door holders, fire dampers, lifts, HVAC systems, and other ancillary equipment.
Designed for precision and reliability, the Morley Addressable Control Module communicates digitally with the fire alarm control panel via the analogue communications loop, enabling real-time monitoring, supervision, and control of connected field devices. Available in multiple configurations — from single output modules to multi-channel variants with up to six relay outputs — these modules offer the flexibility to address diverse application requirements while maintaining a compact, space-saving form factor.
Whether you’re equipping a commercial building, an industrial facility, a hospital, or a residential complex, the Morley Addressable Control Module delivers the intelligence, reliability, and performance you need for comprehensive fire protection and building management integration.
Key Features
| Feature | Description |
