Offline Wired Sensor

Why would front door show as offline if it’s wired?

“Offline” is an alert status regarding sensor supervision.

It looks like this is regarding a TAKE-345 Zone, correct? The wired sensor is transmitted as a wireless zone by the TAKE-345. In this case, offline means that the supervision signal from the TAKE-345 zone was missed. If you see this somewhat frequently it would indicate signal interference or range issues between the TAKE-345 and the control panel.

Is your TAKE-345 mounted on or in the old metal panel enclosure? This can affect signaling. It is best to make sure the TAKE-345 is mounted to the wall at least a few inches away from the metal enclosure.
