Subject: microwaves and alarms


Dear Mr. Beavers,
Regarding the List's thread about the microwaves that home
alarms might emit, I felt prompted to share what I know about that:

The sensors, detectors, etc. are placed in all the rooms that should be
protected or monitored. As they all should communicate with the central
unit through a separate wire, sometimes it requires a multitude of wires
and a demolition of facilities to place that wires. So, it is often cheaper
to use wireless communication between the sensors and the central unit. 
It is roughly the same as with a cordless telephone. But there is one
difference: all the sensors are "talking" to the base all the time, so that
the base "knows" they are ready. I don't know how many advanced and
different types of such sensors there are, and are there any "ecological"
ones (that stop emitting when the owner is in the facilities). But if they
emit all the time, what is most likely, they still should not be radiating
more than a standard cordless phone, each. So, if you avoid sleeping near
any of them, it would be like if your neighbor used his cordless phone all
the time - not much, as long as you are not electrosensitive or too
ecologically oriented!!
Anyway,  I would have checked the characteristics of the sensor, if I were
your place - one can ask the company that installed it what is the
frequency and the output power of each sensor's transmitter. If they don't
know it, the manufacturer knows. 

Best regards,
