Guest Bobo Posted April 19, 2005 Share Posted April 19, 2005 Hello, I need to replace the door contacts on my front and back door. The FRONT door has 6 different coloured wires (Black, Red, Blue, Yellow, Green, White). The BACK door only has 4 different coloured wires (Black, Red, Blue, Yellow). I have bought two new 5 terminal contacts. I need to know which wires go to which contact and which wires in particular are paired together. Thanks.

Guest Posted April 19, 2005 Share Posted April 19, 2005 Pass. There isn't a standard wiring colour for alarm systems. You need to connect them to the new contacts in exactly the same way as they are connected to the old contacts. Much easier than us guessing.

Monteey Posted April 19, 2005 Share Posted April 19, 2005 Although i cant give advice on specific colours in your installation, for your information 99% of door contacts will have 2 silver coloured screws, this is the reed switch which the alarm circuit should be connected to, the other 2 or 3 brass coloured screws are used for the tamper connection which is generally twisted together. Thats about as specific we can be.

Monteey Posted April 19, 2005 Share Posted April 19, 2005 I think the trial and error rule applies in this case, as without actually seeing the setup i couldnt give a definative answer Mark Hawks Ex BT Openreach Field Service Now Self employed telecom and data engineer www.mphtelecom.co.uk Also back doing sub contract work in the security industry.

You really need to find out which wires went to the reed on the old contact sets. Who took the old sets out - and why? Link to comment Share on other sites More sharing options...

Breathe deep. As we have said a few times, there is no set standard for the wire colours on a intruder installation. If I was to guess, I would probably be wrong. We can not give you a definate answer. Do you know if the zones are still enabled in the software of the alarm system? You may reconnect them correctly only to find that they are omitted (to avoid tamper). What panel is it? Link to comment Share on other sites More sharing options...
