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):

21

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.

22

PSTN Central Unit

 

2.1

 

 

 

Bus Connection

Requirements

With multi-wire cables, always use a symmetrical twisted pair of conductors (i.e. those that match each other). Standard UTP cables contain twisted pairs.

With special cabling (in the cabin), use the adjoining cables and make sure that the nearest neighbouring conductors do not radiate interference (power cables, video signals, etc.).

Recommendations

Do not lead the bus close to power cables, especially in long-distance sections.

Branch the bus to shorten the total length of sections.

Safety

The bus is electrically isolated from the telephone line circuits according to the EN60950 standard requirements and its low voltage cannot cause any electrical accident.

CU Connection to Telephone Line

LN works in a wide range regardless of polarity and line parameters (refer to Technical parameters). Connect it using the attached cable with an RJ-12 terminal.

Caution

One CU may be connected to one telephone line only and no other telephone terminal equipment may be connected to this line.

2N® LiftNet requires the telephone line exclusively for itself. This means that NOT even a system through which the telephone line goes (priority connection, ESS, e.g.) may be connected to this telephone line.

No double or group serial lines may be used.

No telephone “multiplugs”, even the “intelligent” ones, may be used.

Never connect LN to an ISDN line.

CU telephone network connection options

There are four connection options:

PSTN line

PBX line

GSM gateway

VoIP adapter

23

PSTN Central Unit

 

2.1

 

 

 

Direct PSTN Connection

This is the simplest and most reliable type of connection. High operational costs (flat rate costs) are a drawback of this solution.

Telephone line requirements

No double or group serial line.

The telephone socket including cabling is a property of the telecom company and may not be tampered with.

Other recommendations

Notify the telephone network provider of your LN installation and submit certification upon request.

Your follow-up cabling has to meet all applicable safety regulations.

You are recommended to secure your cabling physically against piracy (with a telephone lock, e.g.).

PBX Connection

This is the least-cost solution where a PBX and an unused PBX line are available.

PBX line requirements

The PBX to be used must work reliably even in the case of power outage. Large PBXs are mostly equipped with a back-up power supply, smaller PBXs usually use PSTN line redirection in the event of power failure. Consult the problem with the technician responsible for your PBX. An error during power outage may result in LN calling an undesired station.

Relevant call access rights have to be assigned to the PBX line to be used (use a standard telephone set to check whether the line can make calls to all required „external”/CO line numbers).

While programming, enter all necessary PSTN prefixes (typically a zero), or (which is a better solution) make the PBX not require a prefix (so-called automatic CO line seizure).

To make dispatching office–lift calls, you have to know the extension number and how to get through to it (dial-in, DISA, operator).

The dispatching office–lift connection may not depend on the operator’s presence, no call redirection to a fax machine in the night mode is allowed, etc.

Other recommendations

Make an agreement with the PBX owner regarding operating costs (LN outgoing calls are billed at the owner‘s expense with the exception of free calls on “green lines”).

Tip

Where a non-stop security or porter’s service is available, the personnel can be trained in rescue operations and LN can be programmed to call this service.

24

PSTN Central Unit

 

2.1

 

 

 

GSM Gateway Connection (Temporary – Substitutes the GSM CU Version, Part No. 501303E)

Used wherever no fixed telephone line is available.

Requirements

The GSM gateway has to be functional even in the case of power outage.

The GSM gateway has to recover its function without requiring the PIN.

Other requirements

Find a suitable place or use a special (directional) antenna where the GSM signal quality is poor.

Secure the GSM gateway SIM card against misappropriation.

With a pre-paid SIM card, monitor the credit use and on-time replenishing.

VoIP Adapter Connection

This is the cheapest solution where a reliable Internet connection is available.

Requirements

The entire system has to be functional even in the case of power outage.

Other recommendations

As the VoIP technology is rather complicated, make sure that the dispatching office personnel monitor connectivity reliably (evaluate the checking calls).

Tip

Some VoIP adapters have two independent telephone lines. A majority of subscribers use just one line and the other line is thus available “free of charge”.

Operation without Telephone Line

LN can be used as an intercom during lift assembly work even without a telephone line. In that case, make sure that the lift blocking function is not activated until the telephone line has been connected.

USB Port Connection

Recommendations

Do not leave a PC connected for a long time unless necessary in order to minimise risk of PC damage due to HV shock from the telephone line during storms, e.g.

Interruption of Operation, Battery Maintenance

Caution

Never leave the batteries discharged for unnecessarily long periods.

If the battery is fully discharged please recharge it as soon as possible.

For a detailed description of situations that require your attention due to the state of accumulators during interruption refer to the Maintenance section. Remember that the state of accumulators is essential for system operation in any case. The Maintenance section also contains instructions for accumulator maintenance, including replacement.

Mounting

Main Board Mounting

This audio unit is mounted behind the lift control panel. Typically, the panel is ready for installation as shown in the drawing below:

4 spot-welded M4 screws

Perforated loudspeaker area

Figure 2.4 Top View of

Mounting Hole Dimensions for

Lift Cabin Audio Unit - Universa

LED holes (optional)

Microphone hole or perforation

To mount the audio unit, you need 4 electrically spot welded M3 or M4 screws, a sufficiently large loudspeaker perforation area and a microphone hole on the inner (back) side of the panel. If needed, you can fix the audio unit on a perfectly degreased surface with a good-quality two-sided foam self-adhesive tape.

Warning

Leave no gap between the lift control panel and the audio unit surface to avoid acoustic loudspeaker fault and acoustic loudspeaker-microphone feedback.

28

Lift Cabin Audio Unit – Universal

 

2.2

 

 

 

Do not use this type of audio unit in a position other than mounted on a sufficiently large board. The acoustic properties of an uninstalled audio unit cannot be guaranteed.

Separate Microphone Mounting

If the microphone is separated (connected by cable) it has a 25×25 mm large board with self-adhesive foil. This helps you mount it easily behind any hole in the panel (the minimum hole diameter is 5 mm, or a group of smaller holes of the same total area). Just glue the microphone directly onto the required place from behind (be sure to degrease and clean the surface carefully before!).

The minimum distance between the loudspeaker and microphone centres is 90 mm. A lower distance may lead to acoustic feedback. A greater distance (within the available 1m cable) does not matter.

Make sure that the glued-on microphone does not pick up (even partially!) the acoustic pressure from the space behind the panel. Such sensing might result in acoustic feedback since the loudspeaker strongly radiates sound into the cavity.

Separate Loudspeaker Mounting

The loudspeaker is equipped with a cable and can be separated from the electronics by simply sliding it out within the reach of the cables delivered (1m). This option is useful where there is not enough space for the whole electronic equipment. Fit the loudspeaker according to the instructions below:

While gluing choose such procedures or adhesives that prevent membrane damage by adhesives and volatile substances, or heat.

We recommend you to keep the loudspeaker sealed to eliminate vibrations.

Frequently Asked Questions Concerning Loudspeaker

Is it possible to use a common loudspeaker for the communicator and floor announcing machine?

No, it is not.

May I use a loudspeaker of my own?

Yes, but make sure that the impedance is 64 Ω. By doing this you assume responsibility for sufficient volume and frequency range.

May I place the loudspeaker on the cabin ceiling?

This placement is not recommended.

May I use a longer cable with the loudspeaker?

Yes, but not with the microphone.
