RE: Door entry system

["Nigel Giddings" <nigel.giddings@xxxxxxx>]

Hi Dean,

This is not quite what is required as he wants the unit to call out on
the line to a mobile for example.

The best found so far is http://www.sjgl.co.uk/pantel/pantel.htm
but at
those prices its coming close to a comfort system, well more than 50%
anyway, and has very limited functionality...

Thanks anyway.

Nigel

Just found the instructions - might make my explaination a little
clearer.

BT1 Door Entry Telephone Interface
The BT1 Telephone interface offers the convenience of operating a door
entry
system from an existing BT style telephone without interfering with its
normal usage. All types of domestic tone-dial telephones are compatible
with
the BT1 including cordless DECT telephones which are of great benefit to
those people with limited mobility.
The interface may also be connected onto a telephone switchboard via a
dedicated trunk line input. Please note, operation cannot be guaranteed
with
every PABX available.

Operation
The BT1 interface appears transparent to the phone line, even if the BT1
is
not powered.
When a call is made from the Entrance panel the phone will ring for a
maximum of 30 seconds, a ringing tone will be heard at the panel. When
the
phone is picked up the visitor can converse with the resident and
operate a
lock release by pressing the 1 key to allow access. The door will be
released for 3 seconds, during which time beeps will be heard at the
entrance and at the phone.
