Compling With the New Carbon Monoxide Detector Law

April 7, 2011 I have been asked the question 'Where Do You Place Carbon Monoxide Detectors?' The law is not very clear, except to state 'in accordance with manufacturers instructions.' I visited the First Alert company web site and they suggest one unit centrally located outside the bedrooms and 1 detector for each level of the house, including basement. If you do visit the First Alert web site, you'll find a nifty coupon good for 10% off the purchase. The site with the coupon is: http://www.firstalertstore.com/store/california-carbon-monoxide-alarm-offer.htm?gclid=CJbX4KT4iKgCFQE2gwodOwktsw . The law becomes effective June 1, 2011 for all residential real estate.
