Fixed firefighting systems - Components for gas extinguishing systems - Part 3: Requirements and test methods for manual triggering and stop devices

This European standard specifies requirements and describes test methods for manual triggering and stop devices of CO2-, Inert Gas- or Halocarbon gas fire extinguishing systems.   Manual triggering devices allow a person to trigger the control device of the fire extinguishing system.   They are either non-electrical orelectrical devices.  Manual stop devices allow a person to initiate the emergency stop function of the electrical control device of the fire extinguishing system. Manual stop  devices are electrical components to operate the emergency stopfunction of the electrical control device of the fire extinguishing system.

Overview

EN 12094-3:2003 is a CEN European standard for fixed firefighting systems, specifically addressing components for gas extinguishing systems - Part 3: Requirements and test methods for manual triggering and stop devices.
It covers manual triggering devices (electrical or non‑electrical) that allow a person to activate a gas extinguishing system and manual stop devices (electrical) that initiate the emergency stop function of the system control. The standard applies to CO2, inert gas and halocarbon gas installations.

Key topics and technical requirements

• Scope: Applies to manual triggering devices (electrical and non‑electrical) and electrical manual stop devices for CO2, inert gas and halocarbon systems.
• Electrical devices: Must comply with EN 54‑11 (Type B) functional requirements (with specified exclusions) and have clear front-face marking.
  • Marking: “MANUAL RELEASE - Gas extinguishing system” (manual trigger) in yellow; “EMERGENCY STOP - Gas extinguishing system” (stop device) in blue. ISO 3864 colour guidance referenced.
• Non‑electrical devices:
  • Pressurized parts (except seals) must be metal; non‑metallic materials must resist test conditions.
  • Pressure performance: must withstand 1.5× working pressure without impairment and 3× working pressure without bursting.
  • Operational force limits: ≤150 N (hand), ≤50 N (finger pull), ≤10 N (finger push).
• Test methods: Defined for electrical devices (per EN 54‑11) and for non‑electrical devices (assembly tests at specified ambient conditions). Test types include:
  • Pressure, strength (burst), function, temperature, operational reliability, corrosion, stress corrosion (for copper alloys), vibration.
• Documentation & conformity:
  • Manufacturers must supply installation, operating, maintenance and design documentation to support testing and conformity assessment.
  • Conformity procedures include initial type testing and factory production control (FPC).

Applications

• Use this standard when designing, manufacturing, testing, installing or maintaining manual release and emergency stop components for gas‑based extinguishing systems in:
  • Data centres, server rooms, industrial process areas, engine rooms, archives and other enclosed hazards where gas suppression is used.
• Helps ensure safety, interoperability and regulatory compliance of manual actuators and emergency stop devices.

Who would use this standard

• Manufacturers of manual triggering and stop devices
• Fire‑protection system designers and specifiers
• Test laboratories and notified bodies
• Installers, maintenance contractors and facility managers
• Regulators and certification bodies assessing compliance

Related standards

• EN 54‑11:2001 (manual call points / electrical manual devices)
• Other parts of the EN 12094 series (e.g., Parts 1, 2, 4–7, etc.) covering control devices, valves, nozzles and component compatibility
