    You know, those white things wired up to the alarm. I *think* they're mains powered, never actually looked at them before :p One of them is flashing now though, can't see how to remove the cover or find a reset switch. Any suggestions?

    Yeah, they're supposed to flash to motion. Is it flashing on and off at regular intervals (without triggering)?

    Do you know the make/model of your alarm system?

    :-D I know! I meant it's constantly flashing, not just a long constant light when motion is detected but a rapid blinking!

    I should have added the other sensors all seem fine, it's just this one. No branding on them that I can see

    Wonder if the motion sensors are battery powered wireless ones and the battery is obviously the way out. Our system has these and I've had to replace batteries last year.

    Yeah, maybe. Is there a knack for getting the battery out? I tried pulling, twisting etc and no joy

    Any chance of a better picture. Would need to know if it is wired or wireless?

    Cover normally pops off by using a coin/screwdriver on the bottom-side of the sensor.

    Is your panel/keypad reading any faults and like the guys said is it battery or wired device

    Thank you all for your tips. The alarm system isn't detecting any faults, the motion sensor is mains powered. I popped off the cover with a screw driver, the alarms went off :-D I have no idea what to do now I can its innards, so I just pushed the cover back on! New unit perhaps?

    If you mean Mains Powered as in Electricity, it is not, it is a 12 volt DC unit so don't worry about electrical shocks.

    The cover goes on top first, if you put it on top first and hold it at about a 20 degree angle away from the bottom of the beam then it should align with the top slots.
    Once these are aligned hinge the cover downwards and the cover should then click into position by means of the middle clip.
