Every reason now exists to make homes more secure: the crime rate is increasing, insurance companies are insisting on adequate protection, and more householders are improving home security, so criminals are seeking out the easier jobs - one of which could be yours! This book provides practical, independent guidance. It shows how burglars work, and how to thwart them. In a jargon-free way, the selection and installation of alarm systems are described in this practical guide for home-owners.Not to be overlooked is the possibility that the switch and magnet were properly installed originally, but later a new door was fitted, ... Disconnect the loop at the control box. ... The most practical way of dealing with the problem is to just short- circuit the window foil for a period and see if any false alarms are then experienced.
