UNSUPERVISED ALARMS
When an alarm is configured as an unsupervised alarm, the NET5308T-EXP triggers an alarm only when the normal alarm state (open or closed)
changes.
Figure 20 illustrates the alarm and no alarm conditions of an unsupervised alarm input. A normally closed alarm input can be defeated with a
bypass. A normally open input can be defeated with a cut.

ALARM CONNECTIONS
The unit includes two 8-pin alarm terminal blocks. These blocks have tension clamps. Use a small screwdriver to open the clamp for a particular
lead. Figure 22 shows how to wire the alarm terminal block and connect it to the NET5308T-EXP.
When wiring the connector:
Use 20 to 28 AWG (0.08 to 0.5 mm
2
) wire that is rated for 250 V or higher. The insulation must be thick enough to protect against
electrostatic discharge (ESD).
Strip the alarm wire to 0.31 inches (8 mm).
Insert the wire far enough into the connector so that the metal is not exposed.
The terminal block is keyed. It attaches only one way to the NET5308T-EXP.
