Author Topic: New Smoke Detectors  (Read 2139 times)

My house has a pair of 120 VAC hard wired smoke detectors.   
They are connected together so that if one goes off it triggers the other . 
So far, no false triggering from the ham station but they are 30 years old and probably should be replaced from a fire safety standpoint.   
My concern is that the new ones will be vulnerable to RF and I will end up with a problem that I didn't have previously.
Is anybody aware of a particular brand that is less susceptible to RF triggering.

My operation is on
     80-10 with 100 watts and occasionally 600 watts.   
     2 meters up to 100 watts
    432 up to 50 watts.
Antennas are outside and roof mounted

Any suggestions would be greatly appreciated

So much of it depends upon your house wiring, the proximity of your own antennas and feedline, grounding, RF levels in the house, etc...

If you are going to replace them you will have the wiring pulled down as you replace the heads. Just be proactive and put ferrites on all the wiring since you will have it apart anyway.

They say to replace them every 10 years (I did mine at about 12 years). 30 years?
