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.

Note: Use two batteries, connected in parallel. Obtain an ADEMCO No. 4100EOLR Resistor Kit. A dual battery
harness is provided with the kit. The kit also contains EOL resistors with spade lug/heat shrink tubing
construction which has been approved by UL and CSFM for fire zone usage. Both batteries will fit inside
the panel's cabinet.
