Mains Failure Alarm
By connecting to the mains power or a 9/24 volt power supply the Temperature Alarm can act
as a mains failure alarm. It will monitor the power connected to the power input and send a text
message alert if the power is disconnected.
When the power is disconnected for a period of 4 minutes, you will receive the text message
alert
POWER LOSS.
When the power is restored you will receive the text message alert
POWER RESTORED.
Battery Backup
When power has been disconnected the unit will revert to the onboard battery backup. The
battery back will operate the alarm for up to 24 hours before it will need to be recharged
by connecting power back to the input.
NOTE
- The battery will only work when the battery is switched on. If you do not switch the
battery switch on then the battery backup will not work. Please refer to PCB reference on
