Long range 700 metre Wireless Door Alert designed to monitor a closed door being opened.

Supplied with a:

  • Long Range Battery Powered Wireless Door Contact.
  • 4 channel Wireless Receiver.

In the event of the Door being opened, the Internal Receiver will chime (adjustable volume) together with the option of adding Flashing LED's, Buzzers, Sirens or Telephone Diallers should your application need it.

Additional Door Contacts can be added including the standard 300 metre model (004-2820) or the long range 700 metre Solar Powered model (004-3800).

Door Contact:

The wireless range between the Door Contact and Receiver is an impressive 700 metres (line of sight) when the Aerial is fully extended, this equates to around 300 - 500 metres in most applications, this can be increased up to 900 metres and by adding a Signal Repeater (004-2910), and far more by adding more.

If the Aerial is not extended, the Wireless range is 300 metres (line of sight).

The Magnetic Door Contact is powered by a 3.6v AA non-rechargeable Lithium Battery, but there is also a Solar Panel which helps power the contact (which increases the battery life).

They are fitted using double sided tape and a couple of small screws in some applications, and would be fitted onto a door and door frame in such a position that both parts are within 1 - 8 mm from each other when the door is closed. The normal location would be on the top ledge about 1/3rd in from the hinge. 


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.
