Helpy 2W-V comes with a built-in speak
er
unit.
It is also possible to connect to the Helpy 2W-V:
-
up to 16 independent 2W speak
er
units by means of the 2-wire bus (4
units with direct power supply from the bus and 12 with separate power
supply)
-
up to 2 passive speak
er
units (or cables with microphone) combined to
the built-in speak
er
unit.
Note:
a 2W speak
er
unit allows to realize an independent voice
point with dedicated pushbutton and indicator lights.
Note:
a passive speak
er
unit must be connected to the Helpy 2W-
V’s
autodialer
or to another 2W speak
er
unit and allows to
double it. The passive speak
er
unit can be installed at max. 6
m distance from Helpy 2W-V (or from 2W speak
er
unit) by
using a shielded cable.
Each 2W speak
er
unit connected over the bus (the built-in speak
er
unit is
included) must have a unique ID. Speak
er
units with the same ID can not have
access to the bus and are not working.
Note:
the identifier 01 must be assigned to the
lift car's
speak
er
unit
(default is assigned to the Helpy 2W-V
loudspeaker
). If the
01 ID is assigned to a 2W speak
er
unit,
2W-V's
loudspeaker
automatically takes the ID 99 (it is possible to
assign a new ID to the
2W-V's loudspeaker
through the code
73).
Assign, using the DIP switch, an ID to each 2W speak
er
unit (see next
paragraph).
Connect the speak
er
units (beware of terminal polarity):
