2.5 Audio Unit – Shaft
Description
This Audio Unit is designed for installation on the lift shaft bottom or lift cabin roof, or
wherever it is necessary to communicate (during lift maintenance, e.g.). The Audio Unit
is enclosed in a robust yellow cover. It is not intended for outdoor use but perfectly
tolerates the conditions in lift shafts: is resistant against fall of small objects, dripping
oil, etc. The ALARM button activates the control centre connection, the TRIPHONY
bottom enables conference connection with the other
s of one and the same Audio Unit
lift. The contains a built-in microphone and a speaker. A handset can be Audio Unit
connected for better acoustic properties. Thanks to its size and robustness, the Audio
has a very good, strong sound. Unit

This type of Audio Unit is operated by qualified people (lift maintenance staff,
e.g.).

Units of the same lift.
Push the ALARM button, for example, when someone falls down the shaft.
The Audio Unit calls the numbers configured in the ALARM memory – set 2

The ALARM button illumination (not required by default) helps you find and
activate the Audio Unit easily in the dark.
