Basic Description
2N®LiftNet (LN) is a communication system similar to the intercom. The audio units
are connected (through a pair of conductors) to a common bus, to which one central
unit (CU) is connected. The CU controls the system operation and provides connection
to the dispatching office. Up to 32 audio units can be connected to the bus.
Each audio unit is uniquely identified: by lift number 1 to 8 and position: shaft bottom,
cabin interior, cabin roof and machine room. The machine room audio unit can be
shared by multiple lifts.
The CU is supplied with 12V DC. It contains an easily replaceable back-up accumulator
battery pack (4 AA Ni-MH cells in a holder). The CU is responsible for battery charging
and status monitoring. It indicates the charging status, telephone line status and
current communication by means of three colour LEDs. It is also equipped with a USB
port to provide comfortable parameter setting, voice message recording and software
upgrade.
