GPI outputs
Analogue
I/O
The GPO 5 and GPO 6 outputs are reserved for alarm indication and may
each be assigned to any of the video and audio alarm conditions.
Reference video and audio missing will assert an alarm immediately
whereas the silence alarms can be assigned a delay timer to delay the
time after which an alarm is asserted.
GPO tab with 3G-AIP2 fitted in front position and 3G-AOP2 in rear – example
shows GPO 5 alarm asserted due to channel pair C1+C2 being silent for more
than seven seconds and GPO 6 alarm not asserted.
