The Key subprogram defines Key values Key1, Key2 and Key3 as emergency alarm, arming, alarm cancellation and disarming keys. The alarm subprogram judges whether the P2.3 pin of the singlechip is at low level. If the voltage is not low level, the program is circularly judged until the voltage is low level and is executed downwards; if the level is low, the audible and visual alarm circuit is started, the buzzer sounds and the red indicator lamp flickers.
