Important note
The response time is the interval from the SD-BOX receiving the
signal to performing the relevant action. It does NOT include the
lift unlocking zone sensor detection time, the coil activation time
or the drift control sensor state change.
Important note
The batteries are rechargeable and are charged by the SD-BOX
itself. Under no circumstances should any extra charger be
connected between the batteries and the SD-BOX.
Important note
The coil is overexcited to 30 V
DC for a brief period of time to
prevent possible failures in the overspeed unlocking.
