DRM-1 Door Release System

DRM-1 Door Release System t is designed to fit the extensive Morley-IAS range of mounting options and enclosures providing you with flexibility and speed of installation

DRM-1 Door Release System is Additional failsafe mechanism to meet the code of practice requirements of BS7273-4 section 5 . The DRM-1 module has been designed for use in conjunction with the existing output module and wider fire system to meet the requirements of section 5 of BS7273-4 Category A installations

The Morley-IAS door release system is compatible with12-24VDC door hold systems and includes a volt free contact. The door release system can also be used to drive a third party relay, this gives the added benefit of separating the fire system from direct mains connection which could cause significant and extensively damage to the loop and loop devices

The installation code of practice allows for a delay of the activation of up to 120 seconds which can add to the commissioning time on site, the system provides two time settings, one within 3 seconds and the other at 100 seconds to reduce the overall commissioning process
