Operation of a PARKING series barrier in the event of a power failure. In this case, the module switches over - the barrier draws the required energy from the batteries. 

In addition, the module has overcharge and deep discharge protection to protect the batteries. 

The price is without batteries, including installation of the mode. 

Note: If the "AUTO-UP" module is used at the same time, the module opens a barrier in the event of a power failure. This function is used in multi-storey car parks, for example, where an exit is to be guaranteed in an emergency even in the event of a power failure.
