Inputs
The inputs are connected to the jack marked

. The pin layout is
shown in the picture below.
Input 1 is connected between pin 3 and 8, input 2 between pin 4 and
8, etc.
Inputs 1-3 may be configured either as normally open or normally
closed. Inputs 4-5 are always configured as normally open. If input 1 is
configured as normally open, an alarm will be sent when pin 3 is tied to
pin 8. If input 1 is configured as normally closed, an alarm will be sent
when the connection between pin 3 and pin 8 is broken.
