Appendix A: Alarm I/O Connector
The terminal block is used in applications for e.g. motion detection, event triggering,
time lapse recording, alarm notification via email, image storage to FTP locations, etc.
ICA-500 provides a general I/O terminal block with two digital inputs and two outputs
for device control. Pin 1 and 2 can be connected to an external sensor 1. Pin 2 and 3
can be connected to an external sensor 2. Both of the inputs, the voltage will be
monitored from the initial state ‘LOW’. The relay switch of pin 4, 5 and 6 can be used
to turn on or off the external device. The relay switch of pin 7 and pin 8 can be used to
turn on or off the external device. External Inputs/Outputs are working independently.
