From entry level to consummate professional, how does someone become an alarm technician? As many of us have found, the good alarm technician (both fire and intrusion) is a highly sought after asset that can make the difference for a company and their clients.

The following steps are a process to becoming an alarm technician for a company in the security or fire alarm industry.
