Operation and Specifications

Universal AC Power Input: The unit accepts any input power in the range opf 100-240 VAC, 50/60 Hz.

Connector to ES-4000A: This connector carries power to the ES-4000A expansion station, and carries the four audio

channels of the ES-4000A. When a Telex ES-4000A is connected to the PS-4001, each of the four channels of audio is

"broken out" to the respective channel connections.

Intercom Channel Connectors: These connectors carry power to the intercom system and provide termination for the audio

signal of each individual intercom channel.

Channel Status Indicators: The indicators are green for normal operation and red when there is an overload or short circuit.

The circuitry in the unit will automatically reset when the overload or shirt circuit is located and fixed, and the LED will go

back to green.

BAL/UNBAL Selector Switch: This selector switch allows the user to configure the unit for use in either an Audiocoom

(BALANCED) or ClearCom

power requirements, and call signaling requirements. The default setting for this switch is in the Audiocom

position.
