Overview
What it is and how it fits the system.
The Gent 04390-41 is a floor-mounted 24V DC electromagnetic door holder that releases fire doors to close in an emergency, helping prevent the spread of fire and smoke. It provides 200N of holding force at 45mA and features an integral manual release button so the door can be closed without cutting power. Weighing around 700g with a white painted housing and zinc-plated magnet, it operates across a 0°C to +35°C ambient range.
Technical overview
The Gent 04390-41 is a floor-mounted 24V DC electromagnetic door holder designed to release fire doors in an emergency, preventing the spread of fire and smoke. It delivers 200N of holding force at 45mA current consumption and features an integral manual release button, enabling door closure without operating the fire alarm. Weighing approximately 700g, it has a white painted ABS housing with a zinc-plated magnet and includes a spring-loaded release pin that pushes the door clear on power loss to overcome residual magnetism.
Operating within an ambient temperature range of 0°C to +35°C, the unit is fitted with a suppression diode and reverse polarity protection, allowing it to run from a reverse-polarity monitored circuit. Its low-profile, flame-retardant housing provides easy cable entry and exit. Certification covers EN61000-3-2, EN50081-1, EN60950, and EN1155 (CPD Approved). Physical wiring details are referenced in the installation manual.
