Alarm Triggering
An alarm event happens when any one or more digital and analog input changes state. REX continuously
monitor the input for these events. When an alarm event occurs, it picks up information from the
configuration memory and performs the necessary SMS actions. In such an event, all mobile phone
numbers stored in the memory will receive the SMS alert.
The format of the message is
[Date/Time] [Device ID] [Input description]
→
[Status]
Date/Time
The time of alarm event occurs. The real-time clock within REX provides the time stamping information.
Device ID
The identity assigned by the user during software configuration.
The user defines input description and status during software configuration. Each digital input will have its
own unique input description name and status text.

29/12/12 14:39> (REX) Power Supply in Basement 1 → Fault
Up to 10 mobile phones can be alerted to. This group of phone numbers is known as operation phones.
