300 metre Wireless Gate Contact Alarm System designed to monitor a closed Gate or Roller Shutter Door.

Supplied with a:

  • Battery Powered Wireless Transmitter (fitted inside a weatherproof box).
  • A Magnetic Contact Switch & Magnet.
  • A 4-channel Wireless Receiver (with Relays, 12v Outputs & Volume Control).

In the event of the Gate being opened, the Internal Receiver will play the chosen sound at the chosen volume level together with triggering the 12v Output & Output Relays (which can be connected to Sirens, Lights, Alarm Panels, GSM Diallers etc).

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 with the Transformer supplied (2-pin available upon request).


The Indoor 4 - Channel Wireless Receiver is powered by a standard 3-pin Plug in Transformer and has the following features:

  • 4 x Adjustable Dry Relay N/O or N/C Outputs (often used to trigger auto-diallers, timer relays).
  • Adjustable 12v DC Outputs (often used with sirens & flashing lights).
  • ON/OFF Switch.
  • Volume Control.
  • Will work with up to 128 sets of Sensors.
  • Optional Reminder Bleeps.
  • Exit Delay Option.
Additional Receivers (004-2790) can be added (no limit) to be used in different rooms or buildings. 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.
  • Solar Sirens (for use as an alert or siren).
  • Additional Receivers.
