BS7273 part 4 2007 is the code of practice governing door holders and door release mechanisms.

The DRM- 1 standalone module is available for retrofit to existing systems and offers a compliant solution to meet the requirements of section 5 of BS7273-4 Category A installations by ensuring the fail safe operation of actuation of release mechanisms in conjunction with the existing output module and wider fire system.

The module is compatible with 12-24VDC door hold systems and includes a volt free contact.
