It does not provide equipment to installers; it simply monitors and contacts local authorities if an alarm goes off. The company utilizes passwords in the event of an accidental alarm. If the alarm goes off when it shouldn't, you must call Monitronics and provide a pre-determined password to cancel the alarm. If you plan to change your passcode, you must know the old pass code or else Monitronics will not change it.
