Zeta Magnetic Door Holder 240V AC

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.
