How does P.A.F.S.S work?

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

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 a 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.

PAFSS System Drawing Direct System


PAFSS units are straight forward to install and maintain. Once installed they last for 10 years and simply require an annual service every year similar to a fire extinguisher.

These systems can protect up to 4 simultaneous enclosures making them a good alternative to the more costly room suppression systems that are often used. The clean agent extinguishant is environmentally friendly, non-toxic and will not cause corrosion if discharged.

For added flexibility the installations can be fitted with warning alarms that activation has occurred or alternatively be connected to the fire alarm system.
