Beware also of someone who offers to install a system free in exchange for referrals. In such schemes, if other prospects you refer to the salesperson also purchase the system, you get yours free. But you may well find yourself with no referrals and having to pay the full price of an overpriced system. If you have any reason to doubt a firm's reputability, contact a Better Business Bureau. There are two types of detectors to warn the family about fire.
Smoke detectors sound an alarm at the first trace of smoke.
They should be installed outside each bedroom area and on each additional story of the house. For extra protection, be sure to install smoke detectors inside the bedrooms, dining room, hallways. Heat detectors are not life safety devices. Heat detectors may be considered for added protection in kitchens, attics, basements, integral or attached garages, and furnace and utility rooms. Proper maintenance also is necessary to be sure the detectors are in working order.
