Electromagnetic Door Holders 960120 400N, 960119 800N
Electromagnetic door holders provide attractive aesthetics and high performance for buildings requiring an automatic door release function in the fire emergency. Retainer Magnets are used as hold open devices for fire protection exclusions.
Honeywell’s electromagnetic door holders provide attractive aesthetics and high performance for buildings requiring an automatic door release function in the event of a fire emergency. Door Retainer Magnets are used as hold open devices for fire protection exclusions (fire protection swing doors, rolling gates, fire shutters with self-locking devices). The fire door is normally held in the open state to allow easy passage and access through busy corridors etc. Controlled by a fire detection or smoke protection control unit, the door retainer releases the door when the power is cut and the over-door closer quickly closes the fire door automatically to prevent the spread of fire and smoke throughout the building.
Integrated into the design is a spring loaded anti-remanence pin which ensures zero residual holding force when the magnet is de-energized, thus enabling faster closing of the fire door. Door holders are fitted with an integral manual release button, allowing the door to be closed without operating the fire alarm.
