This useful kit includes all the features you would expect from a professional burglar alarm. It uses an IC circuit and has an exit time delay to allow you to leave your home before the unit is armed, an entrance delay to allow you to disarm the unit when you return home, an automatic horn cutoff after a period of time, an automatic reset circuit, and of course, N.O. and N.C. loops to allow you to use your choice of optional sensor switches, such as reed switches, snap action switches, etc.
