Fire Rated Electrical Accessories
Fire rated electrical accessories are a key part of a building’s passive fire protection strategy, designed to prevent the spread of fire and smoke through walls, ceilings and service voids. Without proper sealing, gaps around electrical boxes can undermine the performance of fire-stopping systems. Used alongside fire stopping products, they help reinstate compartmentation by addressing service penetrations, which is essential for compliance with building regulations and protection of life and property.

Fire Rated Electrical Accessories for Passive Fire Compartmentation
Fire rated electrical accessories play a vital role in preserving the fire resistance of compartments, particularly where electrical fixtures penetrate walls or ceilings. These fittings are frequently used in areas where services pass through fire-rated constructions, helping restore the compartment’s integrity and insulation performance. They are also critical when upgrading older properties or refurbishing buildings where modern protection standards must be met. Fire rated accessories work in conjunction with other protective measures, such as door upgrade kits, which are used to bring existing doors into compliance with fire safety standards. Together, they form a coordinated system to stop the spread of fire and smoke through common weak points.
The correct specification and installation of these components is essential. Their performance is determined not only by their tested fire rating but by their interaction with the wall, ceiling or surface into which they are fitted. Variations in wall types and construction materials—whether solid block or dry lining systems—require different installation approaches. All installations must be backed by manufacturer documentation, fire testing, and expert assessment to ensure reliability in a real fire. When installed correctly, fire rated electrical accessories significantly improve a building’s ability to contain fire and protect occupants during evacuation.
Fire Rated Electrical FAQs
Can I use fire rated pattress protectors in both solid and plasterboard walls?
Only if both wall types have been tested with that specific product. Installations must match test conditions.
Do fire rated electrical boxes require fire stopping products around them?
Yes, to reinstate the fire barrier fully, additional fire stopping products like sealants or gaskets are often essential.
Is certification required for fire rated electrical accessories?
While not mandatory, third-party certification is strongly recommended and often required on major projects to verify performance.
Can I mix different fire protection systems on the same wall or surface?
Mixing systems should be avoided. Each product behaves differently under fire, and untested combinations may compromise protection.
