3G GSM Audio Intercom supplied with a quality Electronic Door Lock (fail secure model), allows visitors to contact the homeowner who can then communicate with the visitors by Phone together with being able to release the Door Lock.

This kit is supplied with:

  • 1 x 1 GSM Intercom.
  • 1 x Electric Door Latch.

The simple Electronic Door Latch (fail secure model) allows you to automate your locking mechanism whilst in most cases keeping the original lock & keys.

The latch is fitted into your door frame working alongside the original lock, this results in you being able to:

  • As an Electric Lock (operated from the Internal Handset).

This Locking Latch requires a 12v DC supply to release the lock (which would be supplied by the Intercom & Power Supply supplied), it will remain locked during a power cut, we can offer a fail safe (006-2950) model for customers needing it to unlock during a power cut).

The latch is a compact size of 145 (L) x 25 (W) x 30 (D) mm.

The Intercom is programmed by using Telephone Calls or SMS (text message) !!

Operating the System:

  • Visitor Arrives & Presses the Relevant Call Button.
  • The Intercom calls the first key-holders programmed number (if it is not answered it will call the 2nd & 3rd programmed number).
  • When a key-holder answers, two way communication is opened up between Family member and Visitor.
  • If the Family member wants to operate the Door Lock, they press 1 or 4 on their Telephone Keypad (this triggers output relay 1 or 2, which would be connected to the Door Lock)
  • Finish Call.
