I use the X10 security alarm console. I  soldered a socket in series with the
"armed" LED in the console and plugged the low voltage detecting circuit of
an X10 Powerflash unit in to it, and plugged the Powerflash into the mains.
The Powerflash transmitted a X10 on or off code to ECS so it knew when the
house was disarmed or armed. Upon disarming from outside with X10 keyring
remote and receiving the Powerflash signal, ECS events sent another X10 code
to switch on a 12V plug pack connected to the electric door lock (see
Smarthome catalogue) for two seconds. The solenoid receiving 12V ac buzzes
revolving the door frame socket and then you can push the door open (even
after 2 seconds) without using the key. Great when you have an armful of gear!
ECS also switches off Rex10 barking dog alarm and switches on hall lights (if
dark) for 2 minutes, raises heating output to "in residence" level if needed,
and then says "Good evening (morming/afternoon) Kevin". When you leave and set
the alarm, ECS does the reverse with a couple of minutes delay.

If you're worried about someone activating the Powerflash unit by transmitting
the 256 codes until they hit the right one, you can put two of them with low
voltage inputs in series. Unfortunately, if you want a deadlock as well,
you'll have to unlock this first with a key. Other better alarm systems are
even easier to interface with ECS.

Cheers!
