the V 9923A code call unit the V 9927A will respond to the contact closure and issue single chimes in response See Figure 2 the beginning of a Code Call sequence the INPUT source will be faded down about 6dB It will remain at this until the CODE CALL sequence has completed including the interdigit time At that time the INPUT source be faded back up to normal level using the CODE CALL option with other tone options the CODE CALL may be interrupted to place other in the sequence including Tone 1 with higher priority However the CODE CALL may be out of sequence the period that this occur ON
