RADIO LINKED SMOKE DETECTORS

In Scotland the fire detection laws are changing. As from February 2022 we must have either wired or radio linked alarms in all rooms meaning multiple devices.

I know devices are ok with wireless internet but not sure if radio frequency is the same thing.

Obviously they would be a cheaper option than wiring but not completely comfortable with the safety aspect for devices. 

I'd be grateful for any advice please.

Thank you

Radio Frequency

Hi Lizzie - Yes - wifi (wireless internet) devices use radio frequency communication to function. Buetooth-connected  wireless devices are also on the radio frequency spectrum.  So similar technology to what we're already using in our homes would be employed in a networked alarm system that uses radio frequency communication.  Glad to hear that these important fire safety requirements are going in place, whichever approach you choose.

Wrong frequency

You don't have to worry about wireless signals.  They are on the wrong frequency for the pacemakers/ICD's.  It's like trying to listen to an FM radio station with an AM radio.  

Past tests on pacemakers indicated you had to have the pacemaker within 1 1/2 inches of the emitting signal to affect the pacemaker.  Also had to be of a certain strength.  And those were really old tests.  The newer pacemakers/ICD's are more shielded.  

Finally I've written several times on this forum about how I forgot about having my pacemaker and ended up drilling about 100 holes with a larger 110 volt power drill.  I was using my shoulder to muscle in the drill and my pacemaker was lying on top of the running drill.  No problems.  And my pacemaker is eight years old so it isn't as good as the newer ones.  So the smoke detector signals aren't anywwhere near the strength of the RF generated by the drill.

So quit worrying.  Make sure your home is adequately protected against accidental fires.  
 

well...

First, there is absolutely nothing to worry about. Wireless (just about anything) around the house uses the same frequency band (2.4GHz ISM band) but everything is designed to play nice together, including your pacemaker if it's Bluetooth connected (most later models are).

You know you're wired when...

You have a new body part.
