1200 metre Wireless Door Alert with Blue Flashing LED designed to monitor a closed door being opened.

Supplied with a:

  • 1 x Battery Powered Wireless Door Contact.
  • 1 x 4 channel Wireless Receiver.
  • 1 x Signal Repeater.
  • 1 x Blue Flashing LED with 3 metres of Cable.

In the event of the Door being opened, the Internal Receiver will chime (adjustable volume) together with activating the Blue Flashing LED for a duration of 10 - 60 seconds or 5 minutes (or until reset on the receiver).

The LED is connected to the Receiver via 3 metres of Bell Cable, which can be lengthened upon request.

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

Door Contact & Repeater:

This system is supplied with a Signal Repeater which increases the working range from 300 metres (line of sight) to 1200 metres (line of sight). The signal repeater is powered by a plug in transformer and needs to be fitted within 100 - 300 metres from the door contact.

The Signal Repeater needs to be fitted into an Internal location or inside a weatherproof container (not steel).

The Magnetic Door Contact is powered by 2 x AAA batteries which would last between 1 - 2 years in most applications.

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.

  • 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.

Additional Receivers (004-2790) can be added (no limit) to be used in different rooms or buildings.
