Fire Suppression Systems for Electrical Enclosures

Electrical enclosures can be found in multiple numbers in more or less every workplace. These small enclosures, including those for distribution, control, communication and servers can present a particular problem where faulty equipment, damaged wiring or improper installation can increase the risk of fire. Fires in such enclosures can be difficult to identify, often until it is too late to take action. This can result in significant damage, destruction and lost productivity due to downtime.


Our PAFSS system installations offer peace of mind for clients looking to specify a fully tested, approved and certified solution for fire protection of their electrical enclosures. 

PAFSS Direct Low Pressure (DLP) fixed fire suppression systems have been specifically designed to protect small enclosures in accordance with Loss Prevention Standard, LPS 1666. 

PAFSS DLP systems provide protection inside the enclosure and discharge at the heart of the fire, extinguishing quickly and preventing the fire from spreading to neighbouring enclosures, equipment and the wider building. This can significantly reduce the risk of injury to personnel and losses caused by down time and operational disruption.

PAFSS Systems once installed are on guard 24 hours a day, 365 days a year.

Applications for PAFSS

What is PAFSS?

PAFSS stands for Pneumatically Actuated Fire Suppression System. These systems are designed specifically to protect electrical enclosures are are certified to Loss Prevention Standard LPS 1666. 

How does it work?

PAFSS systems comprise of a cylinder of clean agent extinguishant that is either fixed to the wall or external surface of the electrical enclosure. A detection tube is connected to the valve of the cylinder and runs through the area to be protected and is sited in close proximity to risk areas where fires are most likely to start. In the unfortunate event that t fire starts the detection tube will be melted by the flame which then releases the clean agent directly onto the site of the fire. As the extinguishant continues to be released the extinguishant will fill the enclosure suppressing any other fire that may be present.


  • Simple to install and maintain.
  • Fast automatic actuation.
  • Linear heat and flame detection allowing for an unlimited number of detection points.
  • Highly reliable detection tube which remains unaffected by dirt, debris and oil.
  • Flexible detection tubing can be located adjacent to the identified risk areas, providing fast effective detection.
  • Requires no power supply for detection or actuation, remaining operational during power interuptions.
  • Superbly engineered specialist valves and pressure vessels containing clean agent extinguishant.
