Magnetic Door Holder 240V AC

Ref: zeta-magnetic-door

Magnetic doors are used to hold open fire doors. In the event of a fire, power is removed from the magnet, allowing the spring loaded door to shut. Available in mains or 24V dc versions.

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.
An optional Floor mounting bracket is also available. There are 2 versions, 24V dc and 240V ac.
The 24v DC door holder requires either a panel with a 24v DC output, or a separate 24V PSU. 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 -).
The 240v AC door holder is powered through the mains. Unless otherwise stated in the FACP manual, these MUST NOT BE SWITCHED THROUGH THE FACP AUX RELAY. (Most FACP relays are SELV-low voltage).
Fit a mains rated relay driven from the sounder circuit, and switch through this relay instead.
