Description of Jumpers
P1 (BURST/CONT) - Sets the mode of the V-9927A. The BURST function allows one (1) tone (or sequence)
for each closure of the TONES input. The CONT function is continuous; the tone (or sequence) will
repeat while the closure on the TONES input (1-8) remains activated.
P2 & P6 - Not used on this version.
P3 (TONE BANK Select; OUT/IN) - Activates tones. Refer to the Tone Table (page 2) to determine jumper
placement for the desired tones.
P4 (UNMUTE/MUTE) - Determines if SIGNAL IN is muted or unmuted. With UNMUTE selected, the signal
returns after completion of a designated tone (or sequence) even if the relay on the TONES input (1-8)
remains connected. With MUTE selected, the signal remains off after completion of tones even if the relay
on the TONES input (1-8) is connected.
P5 (OUT/IN) - Determines the fadeout duration of the Input Source. The INPUT source will be faded out in 0.75
seconds if P5 is OUT or will be faded out in 0.25 seconds if P5 is IN.
