System Start-up

The Click&Go logic provides the IF condition to perform an action, such as triggering the local output or SMS

alarm to indicate that the system is restarting.

More Information about Repeat Interval vs. Edge Detection

Combining the Timer function with other IF conditions allows actions to be repeated when the specified logic is

sustained over a period of time. However, if a condition is based on edge detection (i.e., ON to OFF or OFF to

ON), it can only be triggered once.

The following scenarios illustrate how edge detection affects the Timer = N sec. In each diagram, the statuses

of three sensors are shown over a period of time, with a high signal corresponding to a “true” condition. The

green shaded area shows the duration of time that the IF conditions have been met.

No Edge Detection

In this scenario, the rule checks each sensor for “on” status, so edge detection is not involved. As long as the

sensors remain on, the required conditions are satisfied, and the THEN actions will repeat at interval N.

DI-0 = ON

DI-1 = ON

DI-2 = ON

Edge Detection for All Conditions

In this scenario, the rule checks each sensor for a change from “off” to “on” status, meaning only edge

detection conditions are used. As soon as a sensor changes from “off” to “on”, the condition is satisfied, but

only for that instant. Right after that instant, the condition is no longer satisfied because it is no longer

changing from “off” to “on”. The repeat interval will have no effect, since edge conditions cannot be sustained

over a period of time.
