Motion sensor trips immediately on arm
Hi all,
I have a DSC Alexor system with a WS4904P motion detector. It's a relatively new system (2-3 years old) and it was never used/monitored until this last weekend when it was activated with a monitoring company.
Whenever I arm the house on away, the motion sensor trips the alarm right away (or at least in the first minute or so but it seems like it's right away). That's with no people or pets in the house, and no sources of movement or heat in the room that I can detect.
I've checked the sensor for spiders/bugs, tested it to make sure it detects movement when off the bracket, and lowered the sensitivity to "slow" mode, but that didn't make any difference.
Does this sound like a faulty sensor, or could there be a programming/setting issue that would cause this?
Thanks
Sam

Welcome to the forums. Mr. RonFL should be along soon. He is the pro on alarms.
I would first verify that it came on immediately and then look for a short circuit. Second guess would be faulty sensor.

Where is the motion detector mounted in relationship to the keypad? Do you have to pass by the motion detector on the way to arm the system? If yes, is it possible that you are not giving the motion detector enough time to quite down before you arm the system?
With the help of someone else you can try this experiment. Position yourself where you can see the motion detector and stay entirely still. Have the other person arm the system and see if the walk test light comes on in the motion detector during the arming process.
If not, it is possible that there's something wrong with the motion detector, or with with the programming of the panel.
Do you have the ability to get into the programming yourself? It's possible that the installer forgot to program the motion detector as a "follower zone" That is ..... the motion detector should give you an exit delay when you arm the system in the away mode.
