Overview

What it is and how it fits the system.

This wall-mounted 24V DC electromagnetic door holder holds fire doors open and releases them to close in a fire emergency, helping prevent the spread of fire and smoke. It delivers 200N holding force at just 22mA and includes an integral manual release button so the door can be closed without removing power. A low-profile, flame-retardant ABS housing, anti-residual-magnetism release pin and suppression-diode DC protection ensure reliable, repeatable release; the door mounting keeper plate is supplied.

Technical overview

04390-31 Magnet Door Holder 24V DC 22mA is a wall-mounted electromagnetic door holder designed to hold fire doors open and release them automatically during a fire emergency, helping to limit the spread of fire and smoke. It delivers a 200N holding force while drawing just 22mA at 24V DC, making it efficient to run within a fire safety installation. A built-in button also lets staff release and close the door by hand without setting off the alarm.

When power is lost, a centrally mounted spring-loaded pin drives the door clear of the magnet, overcoming any residual magnetism so that release is clean and repeatable. A suppression diode and reverse-polarity protection let the unit run from a monitored circuit. It carries EN1155:1997 CPD approval and is designed to comply with EN61000-3-2, EN50081-1 and EN60950.
