Auto Low Battery (ALB) and Auto Presence (AP) Mode Overview
Auto Low Battery Mode
When the battery is low, the monitoring centre will be automatically notified of this
by the Motion Sensor 869. The battery should be replaced within two weeks of
receiving an ‘ALB’ warning. The warning will be issued every seven days until the
battery has run out.
Auto Presence Mode (Heartbeat)
On supporting Tunstall systems, this mode carries out additional checks to provide
reassurance that the Motion Sensor 869 is functioning correctly. When ‘AP’ mode is
active, the Motion Sensor sends a signal to the Tunstall unit every four hours,
effectively acting as a heartbeat. An ‘AP failure’ message will be raised to the
monitoring centre if the Tunstall unit has not seen eighteen consecutive ‘AP’
messages. ‘AP failure’ alarms will be continually generated if sensors are removed
from the property when in ‘AP’ mode and are not deleted.
Note: The default setting for the Motion Sensor 869 is ‘ALB’ mode.
