California State Fire Marshal (CSFM) 24-Hour Battery Back-Up
Requirements
The California State Fire Marshal has published new regulations which require that all residential
fire alarm control panels installed after June 30, 1993 must be provided with a back-up battery
which has sufficient capacity to operate the panel and its attached peripheral devices for 24 hours in
the intended standby condition, followed by at least 4 minutes in the intended fire alarm signaling
condition.
This control panel can meet these requirements without using a supplementary power supply,
provided that the panel's auxiliary power and bell output currents are limited as indicated in the
following table.
