Printed in the United States of America PRINTING 77 78 79 80 81 82 83 84 85 YEAR As the average citizen becomes more affluent, he invests in a house, buys color TV sets, stereos, and the like, and perhaps collects other luxury items such as antiques, rare paintings, and so on. Attracted to such opulence are an alarming number of burglars, drug addicts, and amateur "rip-off artists— all looking for a fast way to make a buck. Although it is difficult to keep up with the statistics on burglaries, it was reported that over a million homes were looted in the past year alone. Crime experts, however, claim that these figures are quite unreliable since many petty thefts are not reported, and that double the number of breakins actually reported could, in fact, be taking place. Years ago, homeowners could boast about leaving their doors unlocked for indefinite periods of time. Then crime started to mount and they were forced into installing heavy locks, steel doors, and window bars. But ingenious thieves picked these locks, cat burglars entered through skylights or basement windows, and the crime wave has continued unabated. Today, the picture is changing, somewhat, thanks to the "electronic watchdogs"— electronic systems that are guarding homes 24 hours a day. These include a variety of devices, such as photo- electric, ultrasonic, microwave, laser, and mechanical or magnetic switches. They are powered by a 1 1 5-volt ac power line and/or batteries. Installation and component costs may range from under $100 for a "do-it-yourself" job to over $2,000 for those who need sophisticated combination systems, custom-installed, to protect their valuables. A sudden fire poses an even more fearsome threat than burglaries. Over a half-million homes each year are damaged or destroyed by fire, with thousands of lives lost in such disasters. Fire hazards can be substantially minimized with the protection of electronic security systems. They perform an invaluable service in immediately alerting homeowners to such emergencies. Fire and smoke sensors, together with burglar detection sensors, can be com- bined into effective burglar/fire systems. Automatic telephone dialers, included in such a system, can summon police when an unauthorized entry is attempted or alert the fire department should a fire be detected. You can install your own electronic system if you are some- what handy with an ordinary hammer, drill, and screwdriver. More- over, you can save hundreds of dollars if your home has a dozen or so entry points that require monitoring by switches or sensors. Installation is easy if you follow the detailed steps outlined— you can plan your own system, prepare your needed material list, pur- chase your material at discount electronic supply stores, install your own system, and, finally, test the working of the system. You do not have to be an engineer or electronic technician to do the right job. Just follow the installation steps described for each device, do a thorough and neat job, and, most of all, be patient. The electronic burglar/fire system offers an excellent method to enjoy a comparatively safe and normal way of living with the added com- fort of k nowing that your home and loved ones are protected by a reliable warning system should an emergency arise.
