An electromagnetic door holder is a fail-safe device used to hold fire or regular doors open under normal conditions and release them automatically in case of power failure, fire alarm activation, or emergency—ensuring safe and compliant egress.
Key Features:
- Holding Force: Up to 60 kg (approximately 600 N)—suitable for standard to medium-weight doors.
- Electromagnet and Armature Plate: The unit consists of a durable electromagnet mounted on the wall or floor. A corresponding armature plate is fixed to the door. When energized, the magnet holds the armature plate firmly. When de-energized (e.g., fire alarm or power cut), the magnet releases, allowing the door to close automatically.
- Release Button (Optional): Some models feature a manual release button for convenient override.
- Power Supply: Operates typically on 24V DC or 12V DC depending on model. Low power consumption: approx. 1–3W
- Construction: Robust metal casing, often powder-coated steel or aluminum alloy Corrosion-resistant and durable for long-term use Suitable for both interior and protected exterior use
- Mounting Options: Wall-mounted or floor-mounted base depending on door type and space constraints Supplied with mounting plate, screws, and instructions
- Finish: Neutral colors like silver, white, or black to blend with various door and wall finishes
- Fail-Safe Operation: In the event of a power failure or fire alarm activation, the magnet automatically releases the door, allowing it to close via a door closer—compliant with fire safety standards.
Applications:
- Fire doors in commercial buildings, schools, hospitals, offices, and hotels
- Can also be used in access-controlled environments to manage door position
