Front door sensor playing up

[CPM1971]

Hi,

We have a Galaxy 2-20 which has been fine other than the occasional battery needing replacing. However, the sensor over the front door - i.e. the one which ultimately sets / triggers the alarm - has started to not react when we come back into the house. So instead what happens is the remote sensor in the hallway spots us as we walk in and sets the whole alarm off. However, the alarm is setting OK when we go out, so obviously the sensor is working well enough for that. I've tried replacing the battery but it makes no difference. We don't have a service contract on the alarm so it would mean a call-out fee if we need to get an engineer in. I have the engineer code so am happy to do any user-service things myself.

Any ideas?

Thanks

Chris

do a walk test and open and close the door.

does it walk test okay?

From what you say you have a 'sticky' contact, there is no fix for that other than replacement.

Like Europlex says, replace it. They're cheap enough!

(Put this one on the "no brainer" pile!)

if it has the terminal connectors on the bottom (contact with input) you could wire in a normal door contact.

However we dont know where the fault is for certain so best to replace completley and to be fair they aren't mega bucks.

Thanks to everyone who answered.

No, it doesn't react at all during the walk test. Seems pretty apparent that it's dead.

So question number two - is it a simple job to replace the sensor? (I'm talking from the alarm settings perspective, not physically putting a new one on the door!).

Thanks

delete the old one add the new one

relatively easy if you know how I suspect.

Hi.

Right, so the new door contact has arrived, but I'm still stuck as to how I actually tell the system that the old one is no longer in use and that I've added a new one. I've got the instalation and programming manual but it seems to have been written prior to wireless technology and doesn't appear to mention how to add or remove door contacts.

Can anyone help?

Thanks

Err, how about a screwdriver? Perhaps because of there having been no further postings you have sorted out the problem <BG>
