Issue with Smoke Sensor 2.5 z-wave protocol 3.67

[satori 0]

Hi.

From time to time, there is a loud single beep. This started when the sensor gave a false alarm.

Now it just beeps and the smoke sensor graph looks like in the image.

 

Is it broken? Is there a way to repair it or should i toss it?

Hello Satori,

 

Dit you find a solution?

 

I have exactly the same problem with 1 (out of 5) smoke sensors (type: FGSD-002 EU).

A few weeks ago (offcourse in the middle of the night) it starts beeping and it never stops.

It beeps once every minute.

 

I removed it multiple times from the Z-wave network (Fibaro Homecenter 2) and i added it again and again.

Also i did some factory resets with the B-button on the Smoke Sensor and i changed the battery but it keeps beeping.

 

I cleaned it by blowing air through the device with a can compressed air and later with a air-compressor.

 

See my smoke sensor graph below this text, it jumps from 20 to 30 after resetting the device, so i think it must be a firmware problem......

No. I think it's just broken and i should throw it away. Of course, it eats through batteries very fast, adding to the cost of this failing device.

I hoped somebody from Fibaro might have an answer but no, so i just gave up.
