Connectors for external LED supplied from Lift1 and connectors for external microphone and

speaker can be used for connecting of these parts on cables, allowing the user to place it

according the construction of the lift cabin. These parts are delivered with the cable version of

Lift1. These parts must be isolated for minimum breakdown voltage 1500 V (see the safety

caution). Induction loop is the Accessory equipment for persons with hearing aid, it can be used

only in very short distance from the loop. When the whole lift cabin should be covered with signal,

amplifier for induction loop must be used, for more information contact producer.

There is possible to equip Lift1 with universal switch remotely DTMF-controlled or by Lift blocking

module to block the lift function during telephone line failure. The Amplifier module is accessory

equipment for increasing volume in noisy environment, it needs external supplying and it is

electrically separated from the power line.

Note

Use 12–24 V DC of any polarity for voltage control. However, make sure that the source is

backed up against power outage. You can also connect a buzzer or horn in parallel with the

ALARM terminal if voltage control is used.

You can also use the NO contact or voltage presence for Alarm1 and Cancel activation and

invert the function using parameters 920 or 916 if necessary – NC contact or voltage

absence for activation. The logic of the Alarm1 functionality can be set automatically when

the device is first time switched on, the input has to be in not active alarm state.

Make sure that the DoorOpen signal is only activated when both the internal and

external lift doors are open and the people can leave the cabin safely.

Telephone Line Connection

Lift1 works regardless of polarity and/or line parameters in a wide range (see the Technical

Parameters section). It is connected via the LINE terminals. A great advantage is that Lift1

requires no additional power supply for operation. For details on Lift1 connection to PSTN, PBX

and GSM gateway lines refer to the Lift1 Connecting Options section.

Don't use LED holders, which are

not isolated for 1500 V for LEDs
