The Fire Alarm!.

Yesterday the alarm went off at 2am,but I didn't hear it.At 9.40 pm it went again, and again at 10.20 pm.Three times in 24 hours is a bit much. The Fire Officer said that there must be an over sensitive sensor, so we are waiting for the installer to investigate it.Apparently this is not unusual in new builds but it has upset a lot of the nervous people.
