The result is easy and accurate setup. With the SSA-424, all need for test tones, nulling adjustments and ducking adjustments have been eliminated. -
Page 6: Front And Back Panel Descriptions
There is a power ON/OFF and call indicator at the left of the front panel. This indicator lights continuously when the SSA-424 is turned on and flashes when an incoming call signal is detected. The remainder of the front panel is divided into controls and indicators for the two separate hybrids, labeled SYSTEM A and SYSTEM B. -

GPI input #1; however, you may use any other available GPI inputs and outputs. The Call Enable/Inhibit connection is optional. It gives you the ability to disable call signaling using a GPI output. However, when connecting to a Clear-Com intercom system, if an enable/ inhibit switch is not connected, a jumper must be installed as shown to enable call signaling. - Page 12 Table 2.

Operation ENERAL NSTRUCTIONS 1 Attach the power pack to the SSA-424, and apply power to all components. Confirm that the power indicator is lit on the SSA-424 front panel. 2 The power indicator flashes when a call signal is received fron a 2-wire line. The SSA-424 level displays should help to confirm which line is calling. -
