INTRODUCTION
An ASL wireless intercom system may consist of
1-channel beltpacks (WS-19), 2-channel
beltpacks (WS-29), 2-channel base stations (WS-
200) and 4-channel base stations (WS-400).
It is a stand-alone system but may also be the
wireless extension of a wired intercom system.
The base stations have a built-in interface to 4-
wire and to 2-wire (party line) intercom.
The WS-19 is a single channel wireless beltpack,
housed in a strong aluminum case. The unit has
a Volume (listen level) control, a TALK and a
CALL button with LED indicators and one TX/RX
(send/receive) module.
ASL uses the 2.4 GHz frequency band for the
communication between its wireless beltpacks
and base stations.
A maximum of 8 full duplex wireless connections
can be made, simultaneously operated without
any interference.
The unique ASL Call system provides both a
flashing red LED and a very distinctive and
characteristic sound signal. A momentary push
makes the red LED flash, whilst holding the
button for two seconds it will activate the CALL
sound signal. The volume of the sound signal
(buzzer) can be adjusted at the side panel.
Special attention has been paid to the intelligibility
of speech. By applying low noise/high speed op-
amps, a speech presence filter and a specially
developed amplifier, communication is very
comfortable even in environments with a very
high background noise level.

INSTALLATION
The supplied rechargeable batteries are empty,
insert them in the beltpack and charge them
before use. For charging instructions see section
6.0 / #13
The WS-19 is used in an existing or new wireless
intercom system. The necessary DC voltages are
derived from the internal batteries (see section 7.0
/ #16).
Adjust the channel select switch to match the
selected channel on the installed base station (a
WS-200 or a WS-400). After switching on the WS-
19 with the power switch at the rear panel, the unit
should have contact with the base station.
To check this, push a CALL or TALK button.
The green LED
“RX active” and the red LED “1 ch.
Beltpack”
of the corresponding TX/RX module in
the base station should now be lit.
