The Challenge

M&G Fire Protection were tasked with replacing wireless devices as they were faulty and unreliable for door retention, the project needed:

• A robust, reliable solution.
• Quick installation with minimal wiring.

The Solution

M&G Fire Protection utilised Apollo’s latest ADR technology to solve this problem. Because the ADR is addressable and wired into the same loop as the fire detection system, it provided reliable door retention that a wireless alternative couldn’t offer.

A conventional door retainer installation requires an I/O unit, Mains Isolator and PSU, as well as the subsequent cabling to connect the additional components. The Apollo ADR is loop powered and didn’t need any additional devices to function. This reduced installation time and cost significantly.

Three devices were replaced, two on a double door and one on a single door.
