Current limited +5V connection. This terminal can be used as a

connection for pull-up resistors, if required.

Alarm relay output. Indicates fault conditions. The relay is internally

connected to the GND terminal when no faults are detected (i.e.

a normally closed relay). The relay circuit opens when a fault is

detected anywhere in the system.

Signal ground reference. This terminal can be also be used as a

connection for pull-down resistors, if required.

Electrical data inputs. See Figure 6 for data connections.
