CODE REFERENCE
Quick-reference lookups organized so you can find an answer in the field without digging through a PDF.

COMMON VIOLATIONS
A running reference of the violations inspectors flag most often, so you know what to check for before the AHJ does.

NICET PREP
Practice questions across NICET Fire Alarm Systems levels I through IV, with every answer explained, so you can study on a lunch break or between job sites.

Everything runs offline once loaded, so it works with no signal on a job site.

Built by a practicing NICET Level IV fire alarm technician and Connecticut licensed contractor.
