GENERAL DESCRIPTION
The Bi-Way system is designed for hands-free, voice-controlled duplex conversation
between counter personnel (operator) and their customers on the other side of a glass partition.
The operator’s unit is easy to fit on the operator’s counter or wall. The operating modes are marked with logical symbols
and indicated by information lights.
The loudspeakers and microphone on the public side can be mounted in alternative ways and are easy to fit on any
surface such as glass, wood, metal or concrete.
In addition to the basic Bi-Way kit there are several optional elements, e.g. operator’s gooseneck microphone, handset or
headset with microphone for noisy areas, flush-mount loudspeakers for public side and hearing aid radiator.
Area of Application
Bi-Way is ideal for areas where security from violence and vandalism is essential or where noise or health problems●
are of importance such as:
Cash counters in banks and post offices–
Embassies–
Petrol stations–
Gates and doors to restricted areas–
Ticket counters in railway stations and airports–
Treatment labs and isolation wards in hospitals–

space behind the loudspeakers to open the cabinets for subsequent service
of the elements.
Self-adhesive tape:
Clean the glass screen and loudspeaker cabinet with alco-pad before position-
ing the cabinets.

Mounting the movement detector
The physical mounting depends on local circumstances and detector type.
Typical mounting would be above the counter glass or in the ceiling. Be sure the
detector does not react on incidental bystanders or persons at a neighboring
counter.
Connections
Route the switch/power cable(s) from the detector through one of the sta-
tion breakouts and secure by a strain relief.
Connect the n.o. switch cable to P12-1(+) and P12-4 and the detector
power cable to P1-5(+) and P1-6(–)
Operation
Place the operator’s unit in standby mode (push the green button). The●
movement detector will switch to operating mode when activated.
The standby mode must be reestablished by pushing the green button once●
when the customer leaves.
The sound damping on the operator’s side is -6 dB in standby mode. If●
more damping is required the value of R39 (3K3) could be lowered.
Operator’s Side
Basically the operator’s unit and the
power supply are the only units on the
operator’s side.
The operator’s unit can be●
placed freestanding on the desk,
fastened to the wall by screws or

clip, through the small holes at the microphone end.
Separate the front and rear covers.
All connections are made to terminals on the board in the
front cover.
