Before You Start

CU installation conditions

The Central Unit (hereinafter referred to as CU) is not intended for outdoor use.

Do not install 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 switchboard unless the temperature exceeds the acceptable limit. Remember that a higher ambient temperature reduces the life of backup rechargeable batteries in the CU.

It is recommended that the CU should be operated in the upright position with the cable openings at the bottom. Such mounting position ensures the lowest temperatures and thus the longest life of the rechargeable batteries. Horizontal mounting is also possible. The upright position with the cable openings at the top (upside down) is forbidden!

After mounting the CU check that the equipment is firmly fixed in place and cannot come loose and drop down into the shaft.

Product Completeness Check

Check whether the product package is complete before installation:

1 central unit

1 main bus terminal

4 bus connection terminals

4 wall plugs

4 wall plug screws

8 cable ties

1 battery connecting cables

1 brief manual

1 warranty sheet drilling template

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 .

The CU is mounted on a wall with the included wall plugs and screws.

Use unshielded wires of the cross-section of 0.75 mm2.

The maximum total cable length is 30 m with the cross-section of

0.75mm2.

For higher lengths, enlarge the supply pair cross-section: PWR (60m–1.5mm2 , or 100m–2.5mm2).

Audio Units – Splitter (CU) Bus Connection

(the CU is used if one lift shaft is connected)

Interconnect the splitter (CU) and Audio Units using a two-wire bus. Mind the polarity.

Caution

2-wire

Use unshielded wires of the cross-section of 0.75 mm2.

The maximum total length per shaft is 600 m.

With multi-strand cables, always use a pair of wires which match each other.

With a tow cable, consider the cable length too.

With special cables (to the cabin), use the neighbouring wires and make sure that the nearest surrounding wires do not radiate interference (power wire, video signal etc.).

2N® TELEKOMUNIKACE a.s., www.2n.cz

30

Tip

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 Network

You can connect the CU to any of the following telephone networks:

PSTN

PBX

GSM

UMTS

VoIP

PSTN

2N® Lift8 works in a broad band regardless of polarity and line parameters (refer to Technical Parameters). Connect it using the enclosed cable with an RJ–12 terminal. It is the most reliable and simplest connection. The disadvantage is the operating cost (fixed fee).

Caution

Only one CU may be connected to one telephone line and no other end telephone equipment may be connected to the line including a product through which the telephone line goes (so-called priority connection – electronic burglar alarm, e.g.).

No dual or party lines may be used.

No telephone “multiplugs” (adaptors), even the smart ones, may be used. Never connect 2N® Lift8 to an ISDN line.

Telephone line requirements:

The line must not be a dual or party one.

The telephone socket and its wiring are usually the network provider's property and may not be tampered with.

Other recommendations:

Notify the telephone network provider of your 2N® Lift8 installation and submit certification upon request.

Your follow-up wiring must comply with the relevant safety regulations.

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

Connection via PBX (Private Branch Exchange)

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

2N® Lift8 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 outgoing calls to all the required numbers).

While programming, enter the necessary PSTN code (typically a zero), or (preferably) make the PBX not require a prefix (so-called automatic connection to the provider's telephone line).

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

The control room – lift connection may not depend on the operator’s presence; no call forwarding to a fax/answering machine in the night mode is allowed, etc.

Other recommendations:

Make an agreement with the PBX owner regarding operating costs (2N® Lift8 outgoing calls are billed at the owner‘s expense with the exception of free calls via “green lines”).

Tip

If there is permanent manning in your building (security staff,

receptionist), train the personnel how to rescue people and program 2N® Lift8 to call this service.

GSM

This is used in particular where no PSTN line is available.

Recommendation

In places with a poor signal quality find an appropriate place or use a special (directional) antenna.

Protect the SIM card from theft.

If a prepaid SIM card is used, make sure that the credit is monitored and topped up in time.

UMTS

This is used in particular where no PSTN line is available. If 2N® Lift8 is connected via

UMTS, the system can be configured remotely using the 2N® Lift8 Service Tool appli cation.

Recommendation

In places with a poor signal quality find an appropriate place or use a special (directional) antenna.

Protect the SIM card from theft.

If a prepaid SIM card is used, make sure that the credit is monitored and topped up in time.

Operation without SIM card or PSTN line

2N® Lift8 can be used as an intercom without an inserted SIM card or connected PSTN line during the lift fitting time. In this case do not enable the lift blocking function until the telephone line is connected.

VoIP

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

2.2 Splitter

Description

The splitter helps connect the CU with the lift Audio Units. It is connected with the CU via six wires (power, audio, data). The Audio Units (audio units) are connected to the splitter using a two-wire bus. The splitter also contains a make/break contact for the lift blocking function. There can be up to 7 splitters (according to the count of lift shafts).

Each splitter must be configured for a different address (lift shaft number) for the system to work. The addresses are 2–8 (lift 2–8). Lift 1 is the CU.

The splitters are connected in series, i.e. one after another (never in parallel), to avoid system instability. A termination resistor (jumper) is mounted on the last splitter (furthest from the CU).

Figure: 2N® Lift8 Splitter

Caution

Local power supply is not supported yet.

Electrical Installation

Main Bus Connection

Remove the push-in terminal board from the main bus connector and connect six wires from the CU maintaining the polarity (power + -, audio + -, data + - ). See the printed figure on the splitter cover.

Main bus

1 … Main bus power +

2 … Main bus power -

3 … Main bus audio +

4 … Main bus audio -

5 … Main bus data + 6 … Main bus data -

Warning

Maintain the connection polarity to avoid a 2N® Lift8 error.

Bus Connection between Audio Units and Splitter

Interconnect the splitter and Audio Units using a two-wire bus. Mind the polarity.

Audio unit bus

1 … Bus for Audio Units + 2 … Bus for Audio Units -

Address Configuration

Configure the splitter address for the given lift using a 10-position switch 0–9 (see the figure).

2N® TELEKOMUNIKACE a.s., www.2n.cz

35

Configure lift 2–8 as 2–8 (set the switch to position 5 for lift 5, e.g.).

Audio Unit Connection

Connect up to 5 Audio Units to each splitter. As the splitter has only 3 audio unit terminals, connect 1–2 Audio Units in parallel. Remove the slide-on terminals from the audio unit connectors and connect the twin-wire. Adhere to polarity to avoid the Audio Unit error. Refer to the schemes printed on the splitter and Audio Unit for the connection polarity.

Requirements

Connect up to 2 Audio Units to one terminal.

With multi-strand cables, always use a pair of wires which match each other. In standard UTP cables the paired wires are twisted around each other.

With special cables (to the cabin), use the neighbouring wires and make sure that the nearest surrounding wires do not radiate interference (power wire, video signal etc.).

Recommendation

Do not run the bus near power wires, especially long sections.

Branch the bus to shorten the total length of sections.

Warning

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.

Lift Blocking Function Connection

Lift blocking is enabled by the contact breaking (opening) when there is a telephone

line (PSTN, GSM, UMTS) fault or if the 2N® Lift8 rechargeable batteries are almost flat. Connect the contact to the relevant input of the control electronics of the lift/group of lifts. The control electronics must ensure that, after the contact opening, the lifts in operation go down to the nearest station and the doors open.

Caution

This function may be mandatory depending on the regulations applicable for the given country and time of installation.

Termination Resistance

Caution

There is one more pin between the main bus connector and lift number configuration, which helps you configure the termination resistance on the last splitter connected (the furthest from the CU).

The termination resistance jumper is disabled by default.

2.3 Audio Unit – Cabin Universal

Description

The user does not come into a direct contact with this product. The control and indication elements depend on the specific installation. The functions of the indication elements correspond to the applicable standards

Figure: Audio Unit – Cabin Universal

Before You Start

Installation Conditions

The panel has to be installation-ready, including speaker perforation.

The panel has to be equipped with the following obligatory elements:

ALARM button;

illuminated pictogram “Request received”;

illuminated pictogram “Connection made”.

The above mentioned elements have been located as required by the applicable regulations.

There must be free space of at least 65×130×20 mm behind the panel.

2N® TELEKOMUNIKACE a.s., www.2n.cz

37

Product Completeness Check

Check the product for completeness before installation.

The cabin Audio Unit package contains (assembled):

1 electronics board

4 terminals slid onto the board; see the photo

1 jumper slid onto the board; see the cover printing

1 mounting panel

1 speaker connected directly or by cable

1 microphone connected directly or by cable

1 cover with printing 5 tightening straps

Mounting

Electronics Mounting

This Audio Unit is intended for mounting behind the lift control panel. Typically, the panel is ready for installation as shown in the drawing below:

Figure: Mounting Hole Dimensions for Audio Unit – Cabin Universal

2N® TELEKOMUNIKACE a.s., www.2n.cz

38

To mount the Audio Unit, you need 4 electrically spot welded M3 or M4 screws, a sufficiently perforated speaker area and a microphone hole. In emergency, you can fix the Audio Unit on a perfectly degreased surface with a high-quality double-sided foam self-adhesive tape.

Safety

Leave no gap between the lift control panel and the Audio Unit surface to avoid acoustic speaker fault and acoustic speaker-microphone feedback. 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 supplied separately with a cable on a 25×25 mm large board with self-adhesive foil, just glue it directly behind any hole in the panel (one hole must have the minimum diameter of 5 mm, a group of smaller holes must have the same total area). Be sure to degrease and clean the surface carefully before!

Requirements

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.

The microphone must be stuck on so that it does not pick up (even in part!) the acoustic pressure from the space behind the control panel. Such sensing might result in acoustic feedback since the speaker strongly radiates sound into the cavity.

Separate Speaker Mounting

The speaker is equipped with a cable and can be separated from the electronics (simply pulled 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 speaker according to the instructions below:

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

We recommend you to keep the speaker sealed to eliminate vibrations and provide electrical insulation.

Frequently Asked Questions about Speaker

Is it possible to use a common speaker for the communicator and floor Audio Unit?

No, it is not possible.

May I use a speaker 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 speaker on the cabin ceiling? This placement is not recommended.

May I use a longer cable to the speaker?

For the speaker yes, but we do not recommend it for the microphone.

Figure: Address Configuration for Audio Unit – Cabin Universal

Note

Make sure that two audio units do not have an identical address to avoid system error.

The position-setting jumpers are employed exceptionally, e.g. where a certain audio unit type is used in a position other than normally intended. To recover the initial address setting, follow the drawing on the cover.

Bus Connection

Polarity must be maintained.

2N® TELEKOMUNIKACE a.s., www.2n.cz

42

Warning

Connection to different, e.g. higher-voltage, cables leads to damage or destruction of the Audio Unit.

Maintain polarity while connecting the Audio Unit to avoid Audio Unit error.

Caution

The Audio Unit is powered via a 2-wire bus. Disconnection of these wires results in the Audio Unit switch-off.

Avoid the Audio Unit address duplicity.

ALARM Button Connection

Requirements

The ALARM button design (colour, symbol, keypad surface, mechanical operation) and location have to meet the requirements of the particular installation.

Button control

Requirements

The ALARM button has to be equipped with a make or break (NO/NC) contact that is not connected with any other circuit.

None of the ALARM button terminals may be connected electrically with any other electrical circuit and no voltage source other than the NO/NC contact may be connected to them.

If one of the ALARM contacts is connected to another circuit, an appropriate isolation strength according to the applicable standards has to be ensured between the contacts.

Procedure

1.Leave the ALARM terminal in the lower position (3).

2.If you use a make contact, leave the jumper as it is (5th pin on jumper 12) – ALARM without jumper fitted (factory setting).

3.If you use a break contact, fit the jumper (5th pin on jumper 12) – ALARM inverted – jumper fitted.

Voltage control

Requirements

DC 12 to 48V voltage

The voltage signal must be active even during a power failure.

Procedure

1.Move the ALARM terminal two pins up into position (2).

2.For activation by voltage connection, leave the jumper as it is (5th pin on jumper 12) – ALARM without jumper fitted (factory setting).

3.For activation by voltage disconnection, fit the jumper (5th pin on jumper 12) – ALARM inverted – jumper fitted.

2N® TELEKOMUNIKACE a.s., www.2n.cz

43

Warning

Ignoring the instructions above may lead to product damage.

CANCEL Input Connection (Door Contact, Optional)

This input helps cancel a rescue request if the lift is fully functional. When the ALARM button is pressed, the system waits for a pre-programmed period of time, which is a little longer than the maximum lift running time. If the lift is functional, it arrives in the required station within this timeout and opens the door. In that case, the rescue request is cancelled. If the door does not open, the request is accepted.

Find out before installation whether the door opening signal is available in the lift cabin.

Requirements

If the lift has a double door, the signal must be active only if both the door sets are open, i.e., if it is really possible to leave the cabin.

The door position signal has to work even in the case of power outage.

Contact control

Requirements

None of the contact outlets terminals may be connected electrically with any other electrical circuit and no voltage source other than the NO/NC contact may be connected to the CANCEL terminals.

Procedure

1.Leave the CANCEL terminal in the lower position (5).

2.f you use a make contact, leave the jumper as it is (6th pin on jumper 12) – CANCEL without jumper fitted (factory setting).

3.If you use a break contact, fit the jumper (6th pin on jumper 12) – CANCEL inverted – jumper fitted.

Voltage control

Requirements

DC 12 to 48V voltage

Procedure

1.Move the CANCEL terminal two pins up into position (4).

2.For activation by voltage connection, leave the jumper as it is (6th pin on jumper 12) – CANCEL without jumper fitted (factory setting).

3.For activation by voltage disconnection, fit the jumper (6th pin on jumper 12) – CANCEL inverted – jumper fitted.

Warning

Ignoring the instructions above may lead to product damage.

The CANCEL function only works when the cabin Audio Unit is set to the cabin position (default).

2N® TELEKOMUNIKACE a.s., www.2n.cz

44

Caution

Remember to program delayed calling to make the CANCEL connection work successfully.

Refer to the electronics cover for the ALARM and CANCEL configuration scheme.

LED Indicator Connection

The current LED technology makes it possible to achieve a relatively good light intensity with a small current. If the lift indicators are illuminated with a sufficiently efficient LED requiring a current of approx. 5 mA (with diode loss of about 2 V), no power supply is needed. See the figure below for the connection.

Figure: Alternative LED Connection for Audio Unit – Cabin Universal

Note

The cables required for this configuration are not part of the standard delivery but are available upon agreement.

In this configuration, the auxiliary indicators on the PCB are not illuminated.

Induction Loop Connection

The regulations that apply to communicator installations may require a mandatory loop for persons with defective hearing in the lift cabin. In that case, connect the loop to connector (10) with any polarity. The loop including a 1m long cable can be part of your delivery if agreed so.

Requirements

The induction loop has to be placed behind a non-metal, non-magnetic cover in the control panel as the magnetic field of the induction loop cannot go through a metal control panel.

The induction loop has to be labelled with an appropriate symbol (ear) placed according to the applicable standards.

2N® TELEKOMUNIKACE a.s., www.2n.cz

45

Volume Configuration

Slightly loosen the four screws and shift the cover downwards. Now you can remove the cover. Use the trimmer located in the bottom part of the electronics to set the required volume level (see the figure below).

Caution

Use the trimmer to set the best acoustic properties eliminating feedback.

External Pictogram Driver

Description

The device transforms the 2N® Lift8 Car Unit LED outputs into a universal pilot lamp, whose outputs are capable of driving two lamps rated at the maximum of 36 Volts, 0.5 Amps.
