Frequently asked questions about Fire Alarm Modification

Do I need a modification certificate for small changes?
Yes. Any change to a fire alarm system, including adding, removing, or relocating a single device, should be recorded on a modification certificate. This ensures the as-built records stay current and the system is retested after changes.
What about compatibility of new devices?
New devices must be compatible with the existing control panel. The modification certificate specifically records that compatibility has been confirmed and that the panel has sufficient capacity for any additions.
