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.
