Magnetic door holder ADR

Electromagnetic fire door retainers allow fire doors to be legally held open in high foot traffic areas, reducing touchpoints and allowing access for all. When the fire alarm is active, fire doors can be released by the panel. Conventional door retainers require separate connections to power and fire alarm system signals. By using the fire system to power the door holder, most of the installation labour is reduced and additional components such as power supplies or I/O devices are not required. Features Loop powered addressable door retainer requiring no separate I/O, mains power or additional cabling to install Charged from the fire alarm loop with isolator incorporated and no batteries to change Uniquely addressed to aid evacuation by enhancing programming control over hold/release states Third party certified to EN54-17 and EN54-18 for use in fire alarm systems. Also approved to EN1155 as a hold-open device
