Materials You'll Need
Because no two situations are just alike, it will be necessary for you to make your own list of materials.
As a guide, however, here is a list of typical materials, with the quantities left blank, for you to fill in as your own requirements and measurements dictate.
10-volt transformer
_____ Door buzzers
_____ Doorbells
_____ Weatherproof outdoor type bells
_____ ft. indoor bell wire
_____ ft. 2-wire weatherproof telephone twist
_____ ft. 3-wire weatherproof telephone twist
_____ lbs. staples (insulated)
_____ entrance insulators (for attaching weatherproof to buildings and poles)
Because your transformer must be wired into your regular house current, you should have some help on this from an electrician or other qualified person. Also, you should get that person to review your plans and materials list before you place an order.
