Frient Develco Smoke Alarm - SMSZB-120

Nobber · October 30, 2025, 9:05am

I thought I had found the perfect smoke alarm after changing from Zwave Fibaro FGSD002’s
I like the fact it has temperature as well
BUT the one in the kitchen sets off sometimes when the kettle is boiled
Is there a way of adjusting the sensitivity of the alarm

thanks

It’s not about adjusting the sensitivity.
It’s about the sensor’s ability to distinguish between water vapor and smoke.

ok I just thought obvs wrongly that this would be the answer, as on the Fibaro you can adjust the sensitivity

This is why optical smoke sensors are not supposed to be used in kitchens or garages. For such an environment, you should use fire sensors.
