1.0 GENERAL DESCRIPTION
The IS-141 Call Beacon is to be connected to an
intercom party line of an ASL analog intercom
system.
The unit is housed in a strong ABS case and
contains a large LED light and a very loud buzzer.
If a Call signal appears on the party line, the LED
light and/or the buzzer are activated.
A Call signal is generated if the CALL button of
one of the user stations connected to the referring
party line is pushed. By pushing this button
shortly, the Call LED’s of all user stations start
flashing. If the button is pushed and held for two
seconds the buzzers of all user stations are
activated. The LED light and the buzzer in the
IS- 141 react accordingly.

small LED’s, emitting their combined red light in
an angle of approximately 270 º horizontally.

loudspeaker. The characteristic and distinctive
ASL buzzer sound is generated by electronic
circuitry in the IS-141.
Light intensity and buzzer volume can be
separately adjusted by control knobs

female connector are mounted, to connect the
unit to the intercom party line (microphone cable
with 2 conductors and one shield).
The electronics of the IS 141 are powered by the
30V DC on the party line, supplied by an ASL
master station or separate power supply .
The IS 141 may also be connected to a multi-
channel speaker station of ASL Digital Intercom.

speaker station.
For the connection between the IS-141 and a
digital speaker station a special cable is needed
