Due to the unfortunate spam call era we live in, many 800 number calls are never answered. This has presented a problem for our monitoring center to verify our customer’s false alarms; this is due to the fact that the monitoring center calls you via 1-800-432-1429. Please save this number in your mobile phone contacts as "Alarm Monitoring". We recommend also including a note specifying that this is an urgent call that should be answered. This info should also be passed on to your emergency list key people.
