Clear and Set Straps:
The clear and set straps provide selection of “#” and “*” or “A”
and “C” BCD outputs to the supervisory decoder. “#” and “*” are
normally strapped to set and clear, respectively, the busy latch
circuit, and station one and two address latches when a
12-button DTMF phone pad is used. The “A” and “C” BCD
outputs are strapped when the “#” and “*” functions are used for
other applications
Reset Strap:
When strapped IN, the internal reset is initiated after three
seconds or after three seconds have passed between digits.
When strapped OUT, reset is controlled externally as described
in the Circuit Description section of this manual.
Digits:
The digits straps provide selection of one, two, or three digit
address codes.
