The Alarm Output provides one open collector transistor alarm output to trigger alarming devices. Upon an Exception,

a VSSI-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.

Following are some basic circuit designs to take advantage of the Alarm Output.
