6.10 Menu “I/O Setting”
For system installation testing, it is necessary to force relay, buzzer and strobe actions.
The Relay Testing forces an actuate vs. de-actuate action, not an energized vs. non-energized
action. Therefore, the user must be aware of those relays which have been defined as normally
energized or normally de-energized.
