GENERAL DESCRIPTION

The PS 19M is a portable single channel user station.

It is housed in a strong aluminium case and is

provided with a steel beltclip.

On the front panel are a Volume (listen level) control, a

Talk and a Call button with LED indicators.

Special attention has been paid to the intelligibility of

speech. By applying low noise/high speed opamps, a

speech presence filter and a specially developed high

power bridged headphone amplifier, communication is

very comfortable even in environments with high

background noise level.

INSTALLATION

This PS 19M will form part of an existing or new

intercom system, and connection to it is straightfor-

ward. There are no separate power connections, or

batteries to install, as the necessary DC voltages are

derived from the intercom master station or power

supply, via the intercom connection cable.

The unique ASL CALL system provides both a flashing

red LED and a very distinctive and characteristic

sound signal. Smooth operation is guaranteed with the

CALL button. A momentary push makes the extra

bright red LED flash, whilst holding the button for two

seconds will activate the CALL sound signal. The

volume of the sound signal (buzzer) can be adjusted at

the front panel.

Fully electronic switching increases reliability and

allows for :

'soft' microphone ON switching, latched or

momentary

remote Mic Mute facility.

After unpacking the unit please inspect for any

physical damage to the unit, and retain the shipping

carton and relevant packing materials for use should

the unit need returning.

If any damage has occured, please notify your dealer

immediately so that a written claim can be initiated.

Please also refer to the guarantee section of this

manual.

To connect the PS 19M onto the intercom system, use

professional flexible microphone cable with 2 wires

and 1 shield only. Connect the system intercom cable

into the LINE connector socket on the rear panel.

Finally connect the listening headset plug into the

HEADSET connector, also on the rear panel.

The PS 19M is fully protected against mis-wiring

(reverse power) or short-circuit in the interconnecting

cables.
