A.5. N/O to N/C Relay Configuration

The on-board relay in the trk-101 provides a single contact which is by default Normally Open (N/O),

enabling it to be configured to CLOSED upon an alarm condition. This is usually configured with a

momentary closure (for example, five seconds), followed by returning to the OPEN condition, to be ready

for the next alarm event.

Should a Normally Closed (N/C) condition be preferred, the relay may be configured by selecting one of the

following two events in the Event Engine:

 Event 1: Triggering event = Power ON

o Action = Activate relay contact – continuous ON

 Event 2: Triggering Event = Detection Alarm (according to your configuration)

o Action 1 = Activate relay contact – continuous OFF – immediately

o Action 2 = Activate relay contact – continuous ON – after five seconds

The above conditions will turn on the relay at Power ON. An alarm will open the relay for five seconds and

close it again.

The above conditions also will create an alarm indication in case of a loss of power.

Note:

The unit must be rebooted after configuration in order for this setting to take effect.

Note:

Event 1 can also be replaced by Triggering Event = ARM. In this instance, the relay will be OPEN

until the unit is armed, at which time it will behave as described above. This may be desirable in

some deployments.
