Up to 8-lift connectivity
Lift cabin, shaft and machine room audio units
Minimisation of interconnecting wiring
Excellent acoustic features
In-built back-up battery pack
Easy control and programming – voice menu

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.

Before You Start
CU installation conditions
The CU is not designed for outdoor applications.
Do not mount the CU onto vibration-producing machines.
Install the CU vertically to allow air flow for cooling purposes (never cover the
CU with any cloth or install it in another closed box).
You may install the CU into the lift switching board unless the temperature
exceeds the acceptable limit.
The CU may be operated in the lying position on a desk at the room
temperature of up to 25 °C.
Product Completeness Check
Check the product for completeness before installation please:
1 central unit
1 terminal – inserted on the bus connector
1 accumulator battery isolation tape is present (sticking out of the cover)
1 power supply adapter conforming 12V DC to the local power network
requirements
1 telephone cable with RJ terminals
2 wall dowels
2 dowel screws
1 manual, either in the printed or CD format
warranty certificate
Checking of Accumulators
Instructions
1. Completely pull out the tape that sticks out of one opening on the back side of
the CU. This tape protects the inserted accumulators against discharging
during storage. With this tape it is possible to store the product (if supplied
including batteries) ½ year since the shipping date, which is indicated on the
packaging. After this period the claims, if any, regarding the battery warranty
cannot be accepted.
2. Do not connect anything to the CU and if any control lamps light up after the
tape has been removed wait a few seconds until they turn off.
3. Now watch the “power” control lamp on the CU carefully for a few seconds (not
in direct sunlight because the flashing is not strong):

PSTN Central Unit 2.1

a. Weak and short green flashing
The battery is OK and fully charged, you may continue with the
installation. If the product was stored for longer period than ½ year, or
under temperature exceeding 25 °C proceed according to paragraph b.
Caution
The product needs to be put in operation after the tape
has been removed.
It can be stored no longer than one week without charging; after having
been fully charged no more than 1 month.
b. Weak and short red flashing
Some battery cells are discharged. In such case connect the 12V DC
power adapter (do not connect any audio units!) and let the CU charge
for at least 24 hours, even after the indicator has starting showing that
the battery is charged. This is a so-called compensatory cycle, which
balances out the condition of the individual cells after a long period of
storage.
c. No flashing
The battery is fully depleted and may be damaged. Replace the battery
with a new recommended type (SANYO Eneloop 2000).
4. You may now install the CU.
CU Mounting
It is recommended to install the CU in a room that is secured against unauthorised
persons, such as the lift machine room, switching station etc. On an easily accessible
place there is a risk of telephone line misuse or SIM card misappropriation (in the GSM
version).
Mount the CU onto a wall using the attached dowels and screws.
CU Connection
Supply
Use the included adapter or a 12V DC power supply with appropriate parameters
(stabilised).
Warning
Never use an AC or non-stabilised DC power supply to avoid CU
damage.
