7. Check with the operator about the function of downstream
systems and components, such as:
•
Turning off of fans
•
Closing of flaps
•
Notification to the building automation system
•
When checking network failure and recovery, does the
detector return to its normal function and does it unlock
again from the ”smoke alarm” state and return to its normal
function when the alarm has been reset? Does the detector
return to the alarm state and lock up if the smoke alarm
persists?
•
The detector can be released by pressing the reset button
or briefly disconnecting the voltage.
•
Release and approve for operation.
