The 1508 Series electromagnetic door holder is a high quality device for use with single doors. The electromagnet assembly is designed for surface wall mounting.
The electromagnet is designed to be surface wall mounted inside a standard single gang outlet box (supplied). Field wiring connections are made to the electromagnet inside the electrical box. The catch plate assembly may be mounted to the door either by through-bolting or by using the concealed surface mounting plates.
Designed to be used on self-closing, swinging doors to automatically isolate an area when activated by fire alarm, smoke detection or sprinkler systems. Can also be operated by manual control — wherever the instant closing of doors is necessitated for safety or for convenience. Hospitals — for stairwell doors, room doors, long corridors, schools — exit door (closes all doors at once by pushbutton control); offices (instant privacy by pushing a button on your desk), nursing homes and public buildings.

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.
