scope:

This standard sets performance requirements for the following product categories

This standard is applicable to monitor assemblies designed to discharge and direct water spray and/or foam onto a fire. Monitors are most commonly operated by manual means but may also have the capability to operate remotely or automatically. In cases where metric sized monitor assemblies are to be examined for Approval, test criteria comparable to the United States equivalent size shall be used.

Master stream nozzles are typically used in conjuction with monitors as a discharge device. Performance requirements for master stream nozzles are established in FM Approval Standard Class 5511.

Requirements for the installation, use, inspection, service testing, and replacement for such monitor assemblies are detailed in the following National Fire Protection Association standards:

NFPA 1962, Standard for the Care, Use, Inspection, Service Testing, and Replacement of Fire Hose, Couplings, Nozzles, and Fire Hose Appliances

NFPA 1965, Standard for Fire Hose Appliances

Approval standards are intended to verify that the product described will meet stated conditions of performance, safety, and quality useful to the ends of property conservation.

Purpose

This standard states Approval criteria for monitor assemblies that deliver and distribute water for fire protection purposes. These assemblies must operate reliably for many years at rated capacities and pressures during emergency fire incidents, despite being idle for extended periods.

Approval criteria may include, but are not limited to, performance requirements, marking requirements, examination of manufacturing facility(ies), audit of quality assurance procedures, and a follow-up program.
