Frequently Asked Questions

What NM license do I need for alarm system work?

You need the ES-3 (Sound and Alarm) license from the CID. This covers fire alarm, burglar alarm, and sound system installations.

What is the ES-7 license for?

The ES-7 covers Telephone Systems including data cabling and telecommunications installations. It does not cover alarm work.

What exams does NM CID require?

NM CID requires both a written trade exam and a business/law exam. Both must be passed to obtain the license.

Can I do both alarm and telecom with one license?

No, ES-3 and ES-7 are separate licenses with distinct scopes. You need both licenses to perform both types of work.
