INSTALLATION
These instructions cover only the installation
procedure of the Valcom V-9932. Please consult
applicable instructions for control equipment or any
other equipment used.
Precautions
All precautions have been taken at the factory to
insure that the equipment functions properly. Please
observe the following precautions or the equipment
may be damaged and the warranty voided.
a.
Unplug the power supply before connecting any
wires or cables to the control unit connecting
block. With power on, accidental bridging of
two terminals with a wiring tool may damage
electronic circuits.
b.
Do not use a lamp tester to check signals. Use a
voltmeter. A lamp tester, when first applied is a
short circuit to electronic circuits.
c.
Do not apply power to the control unit until all
connections have been double-checked.
NOTE: The V-9932 cannot be used to control
music.
