information. For all alarm communication via the GSM network it is very important that it is
investigated if the communication still works in case of power failure.
The lift phone can also be connected to a VoIP system but then a special device must be
mounted close to the lift phone. Sometimes adjustment of the equipment is needed so the
length of the tones (DTMF) from and to the lift phone is not affected by the equipment.
Contact your distributor for more information. When using such devices it is very important
that it is investigated that the telephone line still works in case of power failures.
6.5.2 Connection
with
separate suspension cable
Normally, a separate suspension cable of the type round cable or flat cable is used between
the lift phone and the telephone jack. A separate suspension cable usually gives better sound
quality and less interference. The required length of cable and mounting kit can be ordered
with the lift phone.
Note that the cable brackets included in the mounting kit must be used in order to guarantee
the function. The combined wall and lift-cage brackets comprise bracket, screw, washer and
cable ties.
Check carefully that the cable will not be torn off nor squeezed or rubbed between lift
cage and shaft wall.
6.5.3 Flat
cable
1.
Check that the cable is long enough,
with a margin, to reach the telephone
jack.
2.
Fasten the cable securely until it
reaches the lift shaft wall.
3.
Secure the cable with a wall bracket
according to the figure on this page.
4.
Fasten the lift-cage bracket under the
lift cage with screws, and attach the
cable to the bracket. Alternatively, the
cable can be attached to some
suitable beam on the lift cage instead
of the lift-cage bracket.
5.
Draw the cable to the lift phone and
connect the wires to the terminals
marked ”TELE”.
6.
Fasten the cable with cable ties or
cable clips on the outside of the lift
near the lift phone.
7.
Connect the two central wires in the enclosed modular connector to the suspension
cable wire, and connect the modular connector to the telephone jack in the engine
room. Mark the connection so that it will not be removed by mistake.
