Computer Alarm Output

This is an opto isolated, open collector output capable of switching
2 mA at +24 VDC to within 0.4V of ground typically.

Reference: 8-Pin Cable (P/N 33738)

Pin 8 Blue

GND Pin 2 Black

This output tracks the alarm output (i.e. the conditions for activating
and de-activating this output are the same as for the alarm output).

This output may be used to directly switch small loads such as
computer inputs and low current LEDs. It may also be used to
initiate switching of larger loads if suitable buffer circuitry is
provided.
