# BDACheck

> BDACheck is a practical site for building managers, facilities staff and condo boards who own a BDA system (bi-directional amplifier, also called ERRCS or public safety DAS). Its free tool emails a reminder before each test is due and keeps a test history for the building. It also explains BDA testing, costs, the difference between BDA, DAS and cell boosters, FCC signal booster registration, and inspection checklists, citing primary sources.

- The reminder tool is free and only emails the person who signed up.
- Rules on how often a building must test come from the local fire marshal; BDACheck links to errcscheck.com for jurisdiction rules.
- BDACheck is operated by WhenLeads, a division of DV8 WEB LLC.
