What is security alarm zone ?

Alarm zones are used for distinguish or define attributes of individual sensors or groups of sensors. User can add one sensors or multiple sensors into each zone. When alarm is set off, the alarm host can indicate which alarm zone is triggered so that the user can tell which sensor or which group of sensors is triggered. Different attributes or alarm setting may also be applied for each zone. For example, some alarms allow to arm a certain zones while keeping other zones disarmed. Or some of the zones can be set as 24hour zone for fire detection so that when fire is detected, the alarm will be triggered no matter it is in arm or disarm status.
