1.1 Product Description
Basic Features
 The SingleTalk (ST) is intended primarily for lifts – especially in buildings,
where there is just one lift and no internal communication between the lift car
and the machine room/shaft bottom/lift car roof is needed (2N
® LiftNet is
designed for more complex applications).
 The ST is a Speakerphone in principle. This means that, built-in behind the lift
panel (wall surface), the ST microphone and loudspeaker are used for bi-
-directional voice communication.
 The ST can be connected directly to a PSTN line, being supplied from this line.
Thus, it requires no battery and no maintenance. It can be connected to
any local PBX line or a GSM gateway too (refer to the Associated products).
 The ST cannot be misused to someone else’s debit because it can dial the
pre-programmed numbers only.
 On the top of it, the ST can be provided with various extending modules as
needed either on purchase, or any time later.
