    I'm struggling to find a few bits I need to close out my alarm system after some work at home. I need 2 white window sensors, one door contact and a PIR, all 2-wire. Anyone know where I could pick these up? They appear to be totally obsolete now but I'd like to avoid having to rewire the whole house. Perhaps someone has done a strip out or knows where I could pick up any or all of the above? Thanks.

    Is it an Astec alarm?

    I have a couple of white Astec window sensors that I can give you.

    Standard door contacts can be modified to suit an Astec system by connecting resistors in parallel.

    I am sure a standard PIR can be used with a few modifications.

    You can wire in standard shock sensors and series in the alarm and tamper together. If there are contacts you will need to wire a 680ohm resistor in parallel with each sensor.
    For the PiR you could convert a standard pir using the same resistor across the contact, but you will need a separate pair for 12vdc power.

    I have a few second hand PIRs if you stuck. For the sensors just use any global sensor.

    Yes, but I don't know when that will be.
    Should be this side of Christmas.
    Will give you a buzz before I head up.
