Looking at the account that is referencing, this is an “offline” sensor supervision malfunction which has come and gone a few times lately. You would need to resolve the underlying issue in order to resolve the alerts.
Supervision is a signaling test to verify with the panel that a sensor is still functioning and present. It is a heartbeat signal sent by the sensors. When they are missed by the panel, you’ll see this offline malfunction.
Supervision and signaling in general is heavily influenced by a few things, often in combination:
Distance from panel
Environment (construction, nearby metal, etc.)
Battery levels.
When is the last time that sensor’s batteries were replaced? Was it moved lately?
All batteries have been changed out as of a month ago. The garage malfunction is now gone but those 3 continue to pop up.
That would indicate that the smoke detector is having intermittent signaling issues - or it could indicate a different issue at the detector.
Do you notice the detector beeping and flashing? Watch the detector for the following possibilities as either would result in a loss of supervision message. Basically note the time between the LED flashes to determine the issue:
Alarm Trouble: When the alarm has a general fault, the yellow LED blinks once every four seconds
and there is a chirp every 48 seconds. After 4 hours the panel displays a loss of supervision message.
Alarm Dirty Feature: When the alarm has been contaminated, the yellow LED blinks once every 8
seconds and there is a chirp every 48 seconds. After 4 hours the panel displays a loss of supervision
message.
