Why Choose an Electromagnetic Door Holder?

Electromagnetic door holders are a critical component in building safety systems. By integrating with your fire alarm system, they ensure that doors automatically close during an emergency to limit the spread of smoke and fire — a key requirement in many building codes.

Frequently Asked Questions

Q: What types of doors is the Asia-Teco F39A electromagnetic door holder suitable for?

A: The F39A electromagnetic door holder is suitable for all kinds of single and double smokeproof and fireproof interior doors, making it ideal for commercial buildings, offices, hotels, hospitals, schools, and residential properties with fire-rated door systems.

Q: Does this electromagnetic door stopper work with both 12V and 24V systems?

A: Yes. The F39A features a dual-voltage design compatible with DC 12V and DC 24V systems (±10%), making it easy to integrate into most existing access control or fire alarm systems without additional converters.

Q: How does the automatic fire alarm release work?

A: When your building's fire alarm is triggered, the electromagnetic door holder is automatically de-energized, cutting the magnetic hold and allowing the fire door to close on its own via its door closer mechanism. This helps contain smoke and fire spread, in line with fire safety building standards.

Q: What is the purpose of the manual release button?

A: The emergency manual release button allows any person to physically disengage the door from the electromagnetic hold instantly, without needing to cut the power supply. This satisfies the "Manual First" requirement common in fire-safety product specifications.

Q: Is installation difficult?

A: Installation is straightforward thanks to the rivet wall-mount design included with the unit. An optional floor-mount bracket is available separately for installations where wall mounting is not practical. No specialist tools are required beyond a basic drill and screwdriver.
