When the disconnect switch is activated, what signal does it cause at the releasing control unit?

Explanation:
Activating the disconnect switch in a clean-agent release system triggers a supervisory signal at the releasing control unit. This type of signal is used to indicate that a monitored device or circuit has been intentionally operated or isolated, so the system knows the releasing pathway is not active and requires attention or service. It’s not an alarm for occupants, nor a fault indication; those would be different signal types. The supervisory status tells operators that the releasing circuit has been bypassed or disabled, prompting appropriate action and preventing unintended release.
