3.5 Motion Sensor Input
The TTU-2830™ supports an internal motion sensor as one of its discreet inputs. In this
case, the TTU detects motion and will determine if the device is moving for at least 30
consecutive seconds. If it is moving the device will track at a 5 minute interval for about
350 messages.
3.5.1 Power State Input
The TTU-2830™ can detect if it’s using external power or if it’s using its internal back-
up battering. If the TTU-2830™ is using external power, this input will be in the Low
state. If they have switched to the internal battery, then the input will register in the High
state.
3.5.2 Battery Voltage Critical Input
The TTU-2830™ has a built in low battery threshold of 3500mV, which is tied to a
discreet input. If the battery in the device reaches this limit a Low Battery event will be
sent to Actsoft systems.
