Fire Alarm Code NFPA 72 – Section 21.2.4

“A listed relay or other listed appliance connected to the fire alarm system used to initiate control of protected premises emergency control functions shall be located within 3 ft (1 m) of the controlled circuit or appliance.” This section of the code is in relation to any fire alarm relays that are required to be installed by a fire alarm company. These relays will be connected to our maglock power supplies or access control panel ONLY when using maglocks to secure your doors. It is the client’s responsibility to arrange this work directly with the fire alarm company or through your general contractor; any and all costs will be met by the client and paid directly to the fire alarm company. A permit will likely be required for all fire alarm integrations/relays. It is the client’s responsibility to pay all fees associated with this permit at the time of permit issuance; additional inspections may be required along with additional fees not easily foreseen. If required, CSS will be present for all inspections and will bill hourly.

Strikes, latch retraction, or other devices that don’t impede free egress are not currently required to be connected to a fire alarm relay. Always consult your local AHJ before upgrading, installing, or decommissioning any fire alarm or related systems.

CSS is NOT a licensed fire alarm contractor and cannot provide specific information about your current or proposed system. The information presented here is for general informational purposes and to raise awareness of the likely need for fire alarm relays.
