i need to move an alarm sensor in a room however when i tamper with it the alarm goes off and i have to reset it (despite the fact the alarm isnt set in the first place) even if i open the alarm control panel the alarm goes off)
how can I re position this sensor on the wall without calling in an electrician?

It has a tamper circuit fitted and will go off even if the alarm is not set - you will have to remove it - replace the cover - reset alarm panel - find where to put it - then remove cover again - reset panel - fit it and then set the alarm to test. Some alarms have a full silence mode - but you need the code

If you haven't got an engineer's code( which by the sounds of it you haven't),take the cover of the panel off. The internal alarm normally goes off at this point.
Hold down the tamper spring for the lid tamper. You can do this using some insulation tape.
Reset the alarm the alarm is silenced. (Thankfully).
There may or maynot be a fuse that you can take out to remove the power to all the powered devices ie PIRs.
If not remove all the wires to the sensors at the 12v + terminal.
All the PIR lights in the the sensors will now go out and not respond when you walk in front of them.
Now you can remove the sensor with no fear of shorting them when you pull the wires throught the hole at the back.
You can now re-position your sensor.
Hope for your sake you have enough wire left to reach!

this is a fool proof way of how to do it. open the sensor, cancel the noise at the control panel. now carefully one by one snip all the cables at slightly different lengths (so the ends will be different legths and not touch. leave the coloured remnants snipped ends in the sensor for reference on reconnecting. move the cable to where you want the sensor. reconnect the wires one by one, do not assume the red and black will be the power. when you finish reconnecting put the lid back on and reset the control panel.

they have tamper circuits on them to inhibit 'inside jobs' so people cant open up the sensors and disconnect them then come back later, eg public place, office etc..

a word of caution, diy'ers working on alarm systems is a recipe for disaster, for example if you get it wrong and short the power out a fuse will blow and depending on what panel you have the outside bell may well then ring and you wont be able to stop it ... and alsorts of other potential nightmare scenarios where what looks like a simple job turns makes you wish you'd never started. believe me i run an intruder alarm company.

that said, if you follow the instructions above, with a bit of good luck and the wind behind you, you'll be ok

don't leave the system more than 3 years between service calls there are consumable items in alarm systems that need replacing and testing or it will become unreliable, ie SAB battery in bell, standby battery in panel, tamper resistances on bell tamper swicthes (excess corrosion etc), sticking door contacts, hi-res contacts in PIR sensors, etc etc.

good luck

The tamper fault will sound when you remove the cover, but will stop if you reset, if not twist the two tamper wires together temporally. Disconnect and insulate the other cores to avoid shorts. Move sensor and CAREFULLY re-connect. Fit cover. (A tamper does not normally go into full alarm, in 'Day' mode, just a tamper warning, but it may have been programmed to do so.)
