This would be the second time it's been changed in less than 12 months. Anyway got it changed and this afternoon it's showed as low again! I obviously don't want to have to keep changing the battery weekly as I'm sure it can't be that, is it likely that the sensor is faulty? The alarm was installed 3 years ago and it would be the most used sensor, especially in the last 18 months I know it could be bad batch of batteries but they are expensive to keep changing if it's the sensor
