The Federal Model 300PBX-SB is a telephone interface device which allows station access from a
PABX to a paging amplifier. Input connection to the Model 300PBX-SB is made by means of a
standard modular jack. No other input power is required. The Model 300PBX-SB is designed to
be connected to a dedicated station line in place of a telephone instrument. By calling the station
number to which the 300PBX-SB is connected, a direct paging access is made to the paging
amplifier. When this connection is made, an alert tone is sounded both in the phone and the
paging speakers. After the page, the 300PBX-SB will automatically disconnect either on CPC,
call time out, toll restriction, or by dialing #7.
Output provisions from the Model 300PBX-SB to the paging amplifier includes both an audio
output and a double throw relay circuit to activate the music mute or other function during page.
The audio output is 600 ohms balanced or for direct connection to an audio amplifier input, a
high impedance output with screwdriver level adjust is provided.
