NF S61-932: An amendment that redefines the oversight of actuated devices of safety

Developments to harmonize the oversight of Actuated Devices of Safety

Among the major changes, the standard clarifies the concept of a “shared Actuated Devices of Safety,” which applies only when a device is located at the boundary between two areas of the same type. This clarification is intended to prevent differing interpretations, particularly with regard to doors between smoke-exhaust areas.

Another step forward: the standardisation of signage for safety positions. From now on, if even one Actuated Device of Safety in a smoke exhaust system is monitored in the safe position, all Actuated Devices of Safety in that system must also be monitored in the safe position. A requirement that improves understanding of the systems’ fire safety signals.

The text also clarifies the monitoring requirements for fan control panels: the standby and safety positions must be clearly marked, including for those on single-duct systems. Finally, the standard provides for exceptions for certain self-closing doors, subject to approval by the safety commission and the administrative authority.

Immediate application to new operations

These adjustments reflect a strong commitment to ensuring consistent and compliant safety measures, while allowing room for adaptation to specific configurations. This development requires fire protection system professionals to exercise greater vigilance in the design and maintenance of these systems.

This new amendment takes effect immediately and will apply to all new operations.
