Anyone used Friedland AlertGARD alarm dialler?

I saw them at B & Q reduced from =A380 to =A333 - it "learns" the sound of your burglar and/or smoke alarm going off and rings you to tell you it's going off.

Problem is - it rings me when the cat mews!!

If you have an alarm, why not just use a conventional SDI?

[Murmansk69]

SDI??? What's that - Strategic Defense Initiative/ Star Wars?

Presume it's some sort of dialler contraption but my alarm is 8 years old so I guess I'd need a new control unit?

If you had a Siamese cat you wouldn't need an alarm.

Sounds like a poor solution, liable to give you a nervous breakdown.

I use a real diy solution. When the alarm goes off a pair of relay contacts close and make a modified one piece phone go off-hook. It has my mobile number programmed into its last number redial and a switch has been wired to the keypad to effectivly keep the LNR key pressed so it dials as soon as it goes off hook. In practice a single dummy digit has to be included before the number to get the timing right; it is not usually possible to put a pause before the dialed number.

I might add that this system has been in use for 20 years or so, initially it dialled a radio-pager.

Total cost? about 5 pounds for the phone.

Speech dialer interface, IIRC. It's what they're called on Ebay.

Even at that age most had auxilliary contacts, and that's all that's needed.
