I'm assuming it is a PIR sensor in a room that is tripping the alarm - if it is, and animals can be ruled out - most likely cause is the Sensor is faulty and needs replaced - they are not expensive About �10 - �15 will buy you a good one ( I use ones manufactured by Honeywell and have found them to be excellent )
Or if you want the bees knees of detectors, a Dual tec Sensor which uses harmless microwaves as well as PIR.
They are wasy to replace - and you can DIY six wires Positive, Negative,Tamper x 2 NO and NC.
Once you have the cover removed the alarm will trigger if the tamper circuit is wired into it, just dont allow the positve supply wire to touch any of the other cables or you will blow fuses on the alarm motherboard.

Many of these PIR sensors have a jumper (adjustable connector) inside the box that controls the number of 'pulses' that the PIR device has to sense before it triggers an alarm signal back to the main control. The default position is often 2 pulses but the device is adjustable to 1 or 3. If you have such a sensor, try adjusting this on the one sensor that controls this zone first, by setting to 3.
