N.B.:The low battery signal occurs as a local acoustic alert, during the alarm events of the barrier
and their sending through the radio transmitter if configured.
N.B.:Battery life can also vary due to other factors, such as if the radio transmitter is powered by
the column battery or by the specific climatic conditions of the installation area.
N.B.:The barrier is capable of operating with power up to 2.8V; if the voltage on the battery
measured under load is <3.4V, it means that the lithium battery is almost flat.
