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 motor
room. Mark the connection so that it will not be removed by mistake.
5.4.4 Connection via existing cable
Warning! Ensure that you will not come into contact with any live power cables.
Normally, the existing lift cable (usually a big flat conductor cable) goes to a car cable box,
where you may find unused wires (if any) that can be used for the lift phone. It is important
that the wires to be used are next to each other in the lift cable in order to minimize disturb-
ances. In the event of bad sound quality a separate cable must be used.
1.
Connect a two-wire cable from the unused pair in the car cable box and draw the ca-
ble to the terminal strip marked ”TELE”.
2.
Fasten the cable with cable ties or cable clips on the outside of the lift near the lift
phone.
3.
Connect the suspension cable wire to the telephone jack in the motor room. Mark the
connection so that it cannot be removed by mistake.
5.5 Connection of voltage supply
Note that separate voltage supply is only required if more than one lift phone is to be con-
nected to the same telephone line, or if single-mounted to a line voltage below 25 VDC, usu-
ally an internal telephone switch (PABX).
The voltage supply must come from a source that will work even in case of a power failure,
e.g. the lift’s emergency lighting system, and the converter must have 1500V isolation from
ground; which is necessary in order to avoid disturbing the telecom station. The voltage sup-
ply to the Fältcom ECII® Flex should be 5 VDC and must not exceed 7 VDC. If no existing
emergency power supply is available a separate emergency power source with a built-in bat-
tery can be used. Contact your local distributor for more information.
1.
Connect a two-wire cable to the existing suspension cable wire for emergency light-
ing. Measure to verify the correct voltage between the pins.
2.
Connect the cable to the DC converter input.
3.
Connect the DC converter to the lift phone outlet marked ”DC”.
4.
Connect the DC converter on the outside of the lift and fasten the cable with cable
ties or cable clips.
