Kleinfeldt's Fire and Life Safety Systems are devised with full compliance and in accordance to all NFPA codes, such as NFPA 101, Life Safety, NFPA 5000 and the Building and Construction Safety Code. These codes are designed to incorporate multiple building factors and occupancy requirements to determine the most direct building egress.

When a building is renovated for a completely different use, the NFPA mandates hazard code reclassification. If the newly classified building is trending upwards into a higher hazard category, NFPA codes compel the building to meet all of the requirements of a new construction. In the opposite direction, where a building's new use changes the fire hazard code to one in a lower category, minimum requirements for the newly classified use must be met in all areas except the automatic sprinkler, detection, alarm and communications systems. These systems must also meet all new-construction requirements.

Kleinfeldt offers a comprehensive fire and life safety inspection and—if necessary—a redesign that incorporates a cohesive blend of alarm/detection capabilities: suppression systems, evacuation planning, and a number of other building construction features that vary depending on occupancy, type of facility and use of space. Carbon monoxide detection also features, as Kleinfeldt strives to lower the rate of injury or death as a result of carbon monoxide poisoning.

In some cases, alarm and detection features can include early warning functions, fire department notifications and unlocking of doors. Larger venues sometimes benefit from the integration of voice-communication to provide emergency response instructions to building occupants.
