300 metre Wireless Gate Contact Alert designed to monitor a closed Gate (or roller shutter door) being opened.

Supplied with a:

  • Battery Powered Wireless Transmitter (fitted inside a weatherproof box).
  • A Magnetic Contact Switch & Magnet.
  • A simple plug in Wireless Receiver (with 35 optional chimes).

In the event of the Gate being opened, the Internal Receiver will chime (adjustable volume).

The battery powered transmitter has an impressive 300 metre (line of sight) transmission range back to the chosen Wireless Receiver or Siren (which equates to around 100 metres in most applications), this can be greatly extended by using a Wireless Repeater (004-2910).



The battery powered transmitter is located inside a weatherproof box, this would be fitted onto a Gatepost or next to a Roller Shutter Door.

The magnetic contact switch & magnet would be fitted into a position so that both parts would be nearly touching when the Gate or Roller Shutter Door is closed.

Additional Gate Contact Kits can be added to the system, ref 004-4700.

The Receiver simply plugs into a 3-pin socket (additional ones can be purchased, ref 004-4500) if you want one in multiple rooms.


The Receiver has volume control (4 levels) and 35 different chimes to choose from, allowing you to have a different tune for different Sensors.

The Receiver can be used with up to 32 Sensors & Contacts.

Additional Accessories:
There are many types of additional sensors that can be added to this system, which include:
  • Solar Powered Magnetic Contact.
  • Solar Powered PIR's (indoor & outdoor).
  • Solar Powered Perimeter Beams.
  • Panic Buttons.
