Keeping your Call List up-to-date is one of the easiest and most effective ways to both reduce false alarm dispatching and to speed up response to an emergency situation. The Police and Fire Department usually require someone to be on-site who has keys and access to the house. If there is no one capable of responding, unless the Fire Department or Police Department have a very good reason, they will not be able to investigate the interior of your home or business for fire and/or intruders.
