Installation Instructions
The diagram below shows a typical installation of the VM-1004 Video
Distribution Amplifier Module. A single input signal is split and routed
to three separate isolated video outputs. Since the system is DC
coupled, all portions of the video signal are passed to the various
outputs. The VM-1004 also contains an alarm scheme that will sense
the loss of an input signal and trigger an integral ALARM indicator as
well as activate an optional ALM-1000 Alarm Sensing Module. A rear
panel switch allows this feature to be turned off if so desired.
