Backup Power For Maglocks Guide
When the main power fails, many believe maglocks must leave doors unlocked.
However, battery backed up maglocks are allowed according to IBC / NFPA code. It just needs to be done properly. We examine the five critical steps for using backing up maglock power correctly:
- Understanding Codes
- Calculating Power Budgets
- Factoring In Power Source
- Connecting Power Supply Fire Alarm Loops
- Including The AHJ
In this note, we look at what the code actually says about power backups for maglocks, where they might be illegal, and how to do it right when allowed.
