Magnetic Door Holder 24V (ZT-DR24)
Product Options
The Zeta Magnetic Door Holder is designed to retain a fire door open, against the force of its own closing device.
In the event of a fire, the door holder magnet can be turned off by the fire alarm, allowing the door to shut.
The 24V DC door holder requires either a panel with a 24V DC output, or a separate 24V power supply unit. This can be switched through the FACP aux relay, but it might need back EMF diodes fitted to the Door Holder (1N4002 or similar, stripe to +, non-stripe to -).
An optional Floor mounting bracket is also available here.
