Detector Malfunctions

We have the following errors:
Heat Detector-Malfunction
Flood Detector Malfunction
Freeze Detector Malfunction

What can we do to fix this?

That’s all on a single SMKT3, right?

There is a blinking diagnostic light, count them, and post

Green blink every 12 seconds is NORMAL
Yellow blink every 4 seconds and a chirp is a FAILURE (loss of supervision)
Yellow blink every 8 seconds and a chirp is CONTAMINATED/DIRTY (loss of supervision)
Yellow blink every 12 seconds and a chirp is LOW BATTERIES (low battery message)

Smkt3 wouldn’t have a flood zone.

The sensor in question looks to be the Re219 flood/temp sensor. Typically these are in the basement. A malfunction on all 3 zones would indicate signal issues. Could be a dead battery. May also be sensor supervision error.

What trouble alert does your panel report?

Smkt3 wouldn’t have a flood zone.

Ahh…I missed that. (and no smoke zone)
