Instruction and Connection Manual 4 of 20

1. GENERAL CHARACTERISTICS

The MMk-656 is a hands-free telephone with automatic dialling, which allows full duplex

communication between a lift car and an alarm reception centre or any telephone, to permit the

rescue of people trapped in lifts. Aside from performing this basic function, the equipment has been

fitted with a series of additional features for remote maintenance and monitoring of the lift. It

complies with the European standard EN - 81 28.

COMPACT. The unit incorporates a speaker and microphone, making it ideal for installation

behind the button panel of the car.

EN 81-28. It complies completely with all the requirements of the European standard EN 81-28.

REMOTE PROGRAMMING. The MMk-656 is completely programmable at a distance, whether by a

simple call from any telephone, or from a PC connected to a special modem in the reception centre. In

the first case, programming is carried out using the telephone's own keypad, and feedback is via a

synthesized voice.

INTERCOM. The MMK-656 incorporates an intercom (for the machine room). It is recommended

that the intercom terminal should be one specially designed for lifts, though any terminal at all ought

to work. This telephone permits programming of the set using its keypad, guided by voice assistance.

MULTI-CABIN. Several modules, up to the maximum of four, can be interconnected for a multi-

cabin system sharing a single telephone line, with no extra cabling required.

TEST CALLS. The MMk-656 can also automatically generate periodic emergency simulation calls

(test calls), and this can be so programmed as to monitor the correct functioning of the equipment at

all times, just as demanded by the standard EN. 81-28. If the test call functionality or remote

maintenance are used, it is only necessary to have a PC (or compatible), a modem and automatic

alarm management software.

REMOTE-MAINTENANCE. The set has an RS-485 communications bus to allow extensions to its

basic functions and to add peripherals to it for I/O control, floor announcement synthesizers, PLC

controllers and control systems, etc. Use of these buses allows the set to generate alarm calls in

response to external events and provides it with a remote maintenance system, so as to detect faults

and incidents in the lift control systems.

FLOOR SYNTHESIZER. By simply connecting a graphical module, a totally programmable floor

synthesizer is available at no extra cost.

or action on the equipment).

Complete remote control and maintenance capacity via telephone from the centre.

Possibility of connecting an intercom (telephone) to programme the set or communicate with

the car.

Possibility of connecting one or several graphical floor indicator modules.

Voice synthesizer to announce the floor or for fault advice.

Possibility of interconnecting up to 4 sets on the same telephone line with no need for extra

cabling.

Flush mounting in the panel with M6 through screws or using double-sided adhesive.

Different languages for programming and up to 2 simultaneous floor synthesizer languages.

2. LOCATION, CONNECTION AND START-UP

For optimum device performance, consider the following recommendations and electrical connection

location. Then proceed to start-up.

2.1. Location

The location recommended by MERak for the emergency telephone is in the lift car behind the

button panel, so that a trapped person can use the incorporated speaker and microphone to

communicate with the alarm centre.

In the event that the set cannot be installed behind the button panel, the J7 expansion connector

can be used to connect an audio module where it is desired. To facilitate mounting, the outer casing

has some through slots in M6 format, or the supplied double-sided adhesive can be used.

2.2. Electric Connection

With respect to the most advisable wiring scheme for the set, the ideal is to have a sufficiently

regulated power supply (10 –30VDC, 1A), as close as possible to the equipment. In this way,

unnecessarily long cabling, and capture of electromagnetic interference by the equipment from

adjacent electronic devices in the lift are avoided.

Instruction and Connection Manual 7 of 20

2.3. Start-up

1. Connect the device to the external power supply 10-30 Vdc (J2).

2. Check that the status led is turned on green light and the device plays locution “Lift Car

1”.

3. Connect the battery to the corresponding terminals (J2).

4. WARNING: Never connect the power supply to the terminals intended for batteries B+

and B-.

5. Connect the phone landline (J4).

3. GENERATION OF ALARMS

The emergency telephone MMk-656 is capable of making automatic calls to different pre-

programmed telephone numbers stored in memory, as different switches are thrown.

The different alarm generators are:

- Car alarm switch:

There are two car alarm generation points (see also section 14.14 WIRING DIAGRAM):

1. At the J1 ALC and J1.2 ALC terminals of the telephone module.

2. Connecting the audio module MMk-698/4, at its J2.1 and J2.2connector.

Following an audible countdown in the car, a call to the first number in the bank of registers

dedicated to storage of alarm telephone numbers (bank of registers 02 to 05) is initiated. If

communication cannot be established, the set will make a programmed number of automatic call

attempts to the numbers stored in the following registers.

If, within ten minutes of the generation of the alarm, the car button is pressed again, the set

will not start again from the first number of the list, but from the number following the last one called.

Once this time has passed, when the button is pressed again, the call attempts will again start from

the first number in the list.

- Maintenance alarm switch (SOS):

This alarm can also be raised at different points:

1. A switch at the pair of terminals J1 SOS/EOA and J1 SOS/EOA.

2. At specific terminals of the audio module (see the instruction manual available on MERak

website www.merakeurope.com).

It makes a call to the number stored in the first register of the equipment (register 01). This

switch is designed to offer the installer the possibility of communication with the centre in the event

MERak MMk-656

Compact Emergency Telephone for Lifts

Instruction and Connection Manual 8 of 20

of necessity, without the need to use the dedicated car alarm telephones. If communication cannot be

established, the set will pass to generating a car alarm call.

The entire call process according to the different programmable parameters is given in detail in

the annex to the Manual for Programming in Voice Mode available on the MERak website

www.merakeurope.com.

4. PERIODIC TEST CALL (EN 81-28)

The European standard EN 81-28 demands that the set should make a status verification call at

least every three days.

To this end, the MMk-656 has been provided with two memory registers (06 and 07), where the

numbers of the servers which log the test calls can be stored. Just as with the alarm numbers, it tries

with the first number in the list, and if this is not successful, it tries with the next number.

The factory default frequency of the call is every 3 days.

To avoid repeated calls, with the corresponding expense, arising from an incorrectly

programmed test number or the time interval between calls being too short, it has been so

programmed that when the equipment initiates a test call, it configures itself to make the following

call 24 hours later, but should communication be correctly established with the server which attends

test calls, the set will reconfigure itself again to the test call frequency defined in the database.

5. CLEARING AN ALARM (EN 81-28)

The European standard EN 81-28 requires that when an alarm is raised, the emergency phone

should remain in a special state ("awaiting alarm clearance") until the rescue of the persons trapped

has taken place and the maintainer of the installation confirms some action to clear the alarm, and so

returns the phone to its ready state and clears the alarm at the centre.

The MMk-656 has three methods to clear the alarm:

By a switch on the pair of terminals J1 SOS/EOA and J1 SOS/EOA.

By a programming command by intercom or external call *99#.

By a switch connected to the terminals of the audio module (see instructions on MERak

website www.merakeurope.com).

Until the alarm has been cleared, the equipment will remain in a special state and will indicate

this through its alarm progress indicator LEDs: see section 9

6. ALARM FILTERING (EN 81-28)

The European standard EN 81-28 states that the emergency telephone should be capable, in the

event that the control system detects that the car is not capable of trapping persons (for instance, at

MERak MMk-656

Compact Emergency Telephone for Lifts

Instruction and Connection Manual 9 of 20

ground level with the doors open), the car alarm should be disabled so as to avoid false alarms due to

vandalism.

For this case, the emergency telephone MMk-656 has an input at the pair of terminals J1 FILTR

and J1 FILTR. When this input is short-circuited, generation of alarms from the car is disabled.

7. CONNECTORS

To locate the connectors, see the wiring diagram in section 14.

7.1. Switches (J1)

At the J1 connector, two different switches can be interconnected. These can be

configured either as switches of type normally open (NO) or normally closed (NC), to effect

which the following command should be used *12#.

- At the pair of terminals J1 ALC and J1 ALC the car alarm is connected.

- At the pair of terminalsJ1 FILTR and J1 FILTR, activation of alarm filtering can be connected.

When this input is closed, generation of alarms from the car is disabled. This functionality is

required by the standard EN 81-28 and permits disconnection of the alarm when the car is not

capable of trapping persons.

- At the pair of terminals J1 SOS/EOA and J1 SOS/EOA the switch to generate a maintenance

alarm for the operators, which generates a call to the number stored in register 01 of the

telephone memories, can be connected. This possibility is included so that maintenance

personnel have a direct line in the event of problems, which is totally independent of the

conventional car alarm. It is possible to install various generation points in parallel without

any problem. This switch is not affected by alarm filtering.

Should there be an alarm open, this same switch also serves as the alarm clear switch,

for activation once rescue has taken place, as required by European standard EN 81-28.

- At the pair of terminals J1 AUX OUT and J1 AUX OUT, an LED indicator may be connected, or a

relay activated, depending on the application, with a maximum permitted power of 1W at 12V.

This output performs different functions according to how it is programmed by means of the

parameter *28: it can be activated if a cut in the electricity grid supply is detected, or it can be

configured to generate an output pulse of duration 1 second on receiving a command.

NOTE: The switch terminals are only designed to connect switches, and not to supply

other lift peripherals: connection of other devices could damage the equipment inputs.

7.2. Power supply (J2)

The MMk-656 module is fed by the J2 connector. The equipment supply tension is 10 Vdc

- 30 Vdc.

Connect the regulated power supply at the terminals J2 V+ (10-30 Vdc) and J2 V- (GND).

MERak MMk-656

Compact Emergency Telephone for Lifts

Instruction and Connection Manual 10 of 20

Connect the lead-acid battery at J2 B+ (battery 12 Vdc) and J2 B- (battery GND).

In this way, the set assumes responsibility for charging the battery and performs

measurement of the charge remaining. If desired, the set can generate automatic calls to the

maintenance company for the installation, in the event that the battery tension falls below the

threshold programmable by the user (as required by the standard EN. 81-28), or is

disconnected.

Programming the *08# register, the telephone will make these automatic calls in these

cases. To deactivate the calls, it is only necessary to deprogramme the same register.

If the supply equipment recommended by MERak is not used, a stable and regulated

source should be used, which should be located as close as possible to the set to avoid the

possible introduction of electromagnetic parasites in a long supply cable.

If it is not desired to use an emergency battery exclusively for the telephone (at the

responsibility of the installing company) but grid power only, this should be connected at the

terminals provided for the supply J2 V+ and J2 V-.

WARNING! NEVER connect the mains supply to the battery terminals.

7.3. RS-485 serial communications connector (J3)

Communication with the control system or other devices such as the graphical viewer

may be carried out via the J3 connector, which is an RS-485 interface. For more information see

chapter 15.

The transmission speed, the number of bytes and parity can be modified according to

the needs of the equipment where it is connected, but only by means of programming with the

software serviLift, available at the MERak website (www.merakeurope.com). A more detailed

explanation of how this bus functions can be found in the PC Mode Commands Manual, available

on MERak website.

7.4. Telephone line (J4)

To connect the set to a phone line, the J4.1 and J4.3 terminals should be used. This must

always be an analogue line.

Connection of the earth terminal J4.2 denoted , is used to protect the equipment from

high energy transients in the telephone lines caused by storms and similar phenomena. If the

connection to earth is omitted, the protection devices provided will be totally ineffective. The

equipment will work just the same in this case, but the probability of faults rises considerably.

MERak strongly recommends the use of this earth connection.

It is not recommended to use the emergency telephone connected to an exchange

because in the event of a power failure, availability of the telephone line is not guaranteed.
