Fire Alarm, Security, Audio/Video & Communication
Most consumers are not aware of Massachusetts licensing for security and alarm systems.
In Massachusetts, any company or contractor installing and servicing fire alarm systems must hold a Massachusetts electrical license.
In addition, any company or contractor installing and servicing "Security Systems" must not only hold an electrical license, but also hold a Massachusetts Office of Public Safety "S-License".
Finally, every employee of the company hold a Massachusetts Office of Public Safety "Certificate of Clearance".
Just an electrical license, even a "Master Electrician license", does NOT qualify for security systems without the additional "S-License".
Whether you consider hiring DB Systems or not, be a wise consumer.
Use only a "Specialist" with the appropriate insurance, licenses, expertise, and training. Do not hire anyone who can not promptly produce license and insurance information, or gives any indication that for some special reason, the laws of Massachusetts do not apply to them.
