Frequently Asked Questions
Q: What types of doors is the Asia-Teco F32 electromagnetic door holder compatible with?
A: The F32 is designed for all kinds of single and double smokeproof fire doors. Its extended wall-mount design makes it ideal for commercial buildings, office corridors, stairwells, and anywhere fire doors need to be held open during normal use and released automatically during a fire alarm event.
Q: How does the electromagnetic door holder release the fire door during an alarm?
A: The F32 operates on a "fail-safe" principle — it holds the door open while power (12V or 24V DC) is supplied. When the fire alarm system is triggered, power to the unit is cut, instantly demagnetizing the holder and allowing the door to close under its own closer mechanism. The anti-residual magnetism design ensures there is no delay in release.
Q: Can I test the door holder without triggering the fire alarm system?
A: Yes. The F32 includes a built-out manual release button that lets you test the door release function independently of the alarm system — ideal for routine maintenance checks and compliance inspections.
Q: What voltage does the F32 door holder require?
A: The F32 accepts 12V DC or 24V DC input, adjustable within ±10%. At 12V it draws 140mA, and at 24V it draws 70mA, making it compatible with most standard access control and fire alarm power supplies.
