Fire alarm standby battery periods, cell voltages and test criterion
The fire alarm battery tool reads the two standby periods, the alarm period, the recharge period, the float voltage and its tolerance, the current limit voltage, the nominal cell voltage, the service life and the three monthly test figures, from Clauses 211.5, 212, 213 and 602.7. The periods are minimum periods, so the tool holds a minimum capacity before the factors and never reports less than that figure.
Verified: read against the printed standard, pages 28–30, 73. Checked 26 Sept 2026.
Units: Value h, min, V per cell, years, s or percent
These are the values AmpSize encodes. No text of the standard is reproduced. Verify against the current standard.
