The VSI-Pro provides two open collector transistor alarm outputs to trigger alarming devices. These are Alarm 1 & 2
in the Alarm menu. Upon an Exception, a VSI-Pro can be programmed to trigger a VCR to go to its fastest record
time, have a Quad go full screen, home a switcher, trigger a preprogrammed PTZ, or provide visual or audible
alarms. The VSI-Pro provides two alarm outputs that are rated at 12VDC @ 20mA maximum.
The following are some basic circuit designs to take advantage of the alarm output option of the VSI-Pro.
