Re: Smoke Detector in Parking Garage

["Doug L" <vssdoug@xxxxxxx>]

 I wouldn't use beam detectors in a structure with an 8ft ceiling which
would place the beams somewhere around 7ft, especially in a parking garage
where all someone has to do is place a box on the roof of their van/SUV
while loading/unloading to obscure the beam and trigger a false alarm,
Generally speaking the manufactures of beam smoke detectors do not recommend
their use in occupied areas with 8ft ceilings.
