What are the key benefits of Constant Monitoring of Gaseous Extinguishing Systems?

What are the key benefits of Constant Monitoring of Gaseous Extinguishing Systems?

ISO 14520 is the fundamental regulation for Gaseous Extinguishing Systems, referencing:

  • The need for pipework to be able to withstand the agent pressures on discharge; 
  • The need to test that the room into which they discharge can hold the agent and that the room can withstand the peak pressure of its discharge;
  • The need to monitor contents of liquefied gaseous extinguishing systems.
  • The engineering reality that anything such as a cylinder under pressure needs its contents and its pressure  to be constantly monitored 
  • The under-reporting of accidental discharges or leakages of pressurised fire systems unless fatalities are its consequence
  • The over-reliance on contractors to maintain fire systems at periodic intervals rather than their operational and daily integration into an overall fire and security plan

Overall the assumption is that little needs to be done on a “pressurised, dynamic system” after it is installed and nor is the “protected space” constantly monitored for room integrity and this “agent hold time”. This leaves a clean agent gaseous extinguishing system un-monitored for 364 days a year. No essential machinery in defence, offshore oil and gas or power generating would be left un-monitored for 1 hour per day.  This is the “Ungoverned Space” which we invite you to work with us on to close the gap for your customers and provide added protection, minimising the risk of fire.

How? 

  • The constant and portable Monitoring of liquefied gaseous extinguishants such as NOVEC™ 1230 or FM 200 fire suppression system with Permalevel™ Multiplex and Portalevel™ MAX respectively giving accuracy of +/-1.5mm
  • The conversion of liquid level readings to ones of weight/mass with Portasteele™ Calculator
  • The portable and semi-fixed monitoring of room integrity with Portascanner™ 520
  • The development of constant monitoring capabilities of non-liquefied gaseous extinguishants such as Nitrogen or Inergen – with Permagas™. We estimate that we are in the final 6-8 months of a 2 year project aiming for 1-2% accuracy
  • To critical infrastructure customers who need to integrate their fire systems into their operation in-between the maintenance intervals
  • Rather than to customers who are installing fixed systems for compliance reasons
  • The ability for high asset value customers to minimise risk, deliver business continuity and enhance resilience of their facilities
  • Such customers may include data centres, power generation stations and electricity distribution sub-stations

Who today in the security industry would consider installing an alarm system without monitoring its overall status and integrating the whole of it to the building management system with central monitoring

being an essential part of it? This is a basic engineering principle: build redundancy into one’s systems and monitor critical systems, to protect people or a critical infrastructure or asset.
