Title: Motion Sensor Temperature Range
Post by: tony on August 07, 2004, 11:40:59 AM
Model MS10A motion sensor .... Can this
sensor operate in the hot and cold
temperatures of an outside tool shed?  Has
anyone used this sensor in a non temperature
controlled building?

Thanks

We had a similar (different manufacturer)
motion sensor in an unheated garage.
Originally it used batteries, and when the
temperature dipped to around 40 degrees F.
the alarm stopped working because the
batteries went dead.  We put in more new
ones, and they died in a few days also.  We
had to buy an adapter step-down transformer
so we could plug it in.  We have had no
trouble since.

Direct sunlight also affects the motion
sensors.  I had one at the backyeard which
the sun shines in the morning and it
triggers the motion sensor all the time.
Solution to this is to put a cover on top
of the sensor.

Question:
I am thinking aboutmounting my motion
detector above my refrigerator.This is a
good location in the room  Will the heat
rising from the back set it off? Has
anybody had this happen for the sensor?
Thanks in advance.

Brian: Refrigators normally draw air in from
the back and exhaust it at bottom front. You
can check this by checking airflow while
compressor is running. Either way, you
should be okay locating motion detector
above refrigator. I have some mounted near
heater vents and they work okay.

Jeff:
Mine is the older style. Coils on the back,
so when operating, the heat rises from the
back. I'll try and see what happens. If it
fires off, thenI'll move it to see if the
sensor  still fires off. It is in my
basement, so it may trigger it due to the
cool normal air. any thoughts??
thanks
