An alarm system for protecting premises comprises a fully integrated, alarm detecting cellular phone unit which is linked to various sensors in order to detect the sensor outputs. The cellular alarm unit includes, in addition to cellular phone functions, a formatter or processor for generating an emergency signal on detection of a sensor output, the emergency signal including information on the type of emergency detected. The unit is programmed to establish a cellular connection to a remote monitoring station. The connection is wireless at least from the premises to a local cell site. Once connection is established, the emergency signal is transmitted to the monitoring station via the local cell site.
