Basic Prison Intercom Setup
Below is the basic wiring of the components used for a simple Prison Guard Intercom.
The External Reach Control allows the Guard to adjust the Sensitivity to hear low level
conversations . The stepped control is pulsed to "UP" to increase sensitivty, or step "DOWN" to
reduce the sensitivity. Holding the "Down" control will cause it to auto-increment to the Preset-
Value
Below are the internal jumper settings for the simple Prison Guard functions
