SAPPHIRE® COMPACT Direct Low Pressure System
Automatic Fixed Fire Suppression Systems for Electrical Enclosures

Specifically Developed to Protect Small Enclosures


SAPPHIRE COMPACT Direct Low Pressure (DLP) fixed fire suppression systems have been specifically designed to protect small enclosures in accordance with Loss Prevention Standard, LPS 1666. “Requirements and test procedures for the LPCB approval of direct low pressure (DLP) application fixed fire suppression systems”.


Small electrical enclosures can present a fire hazard at any time, the SAPPHIRE COMPACT system is designed to rapidly detect and extinguish fires. Systems canbe designed to protect enclosures with both natural ventilation and forced airflow.



System Operation


SAPPHIRE COMPACT fire suppression systems require no power for detection or operation. Detection tubing is routed through the high risk areas of the enclosure, providing fast and effective detection. Upon flame impingement or high ambient temperature, the pressurised detection tube will rupture. The extinguishing agent is then discharged from the connected container through the rupture point on to the fire.


Electrically Non-Conductive Clean Agent


SAPPHIRE COMPACT systems utilise 3M™ Novec™ 1230 Fire Protection Fluid, an electrically non-conductive clean agent. If discharged, it does no damage to electronic equipment or the data stored on it and has zero ozone depleting potential and negligible global warming potential.


Designed to protect enclosures with air vents, fans, forced ventilation.


Features and Benefits:


  • Certified to LPS 1666.


  • Protects enclosures with vents or forced ventilation.


  • Requires no power supply for detection or actuation, remaining operational during power  interruption.


  • Can protect up to four enclosures with one system and each enclosure can be multicompartment.


  • Highly reliable detection tube. Unaffected by dirt, dust, debris and oil.





Upon flame impingement or high ambient temperature, the pressurised detection tube, connected to a container holding the suppression agent, ruptures with a burst at the hottest point. The agent then discharges through the burst hole at

the heart of the fire.


Each SAPPHIRE COMPACT Fixed Fire Suppression System can protect one of up to four enclosures, each up to 2 m3, with one system. Each enclosure may be multi-compartmental.
