Intumescent Fire Cages (Product 32)
Fire-rated, metal intumescent fire cages for lights and downlighters. Intumescent downlighter cages create a fire seal to maintain integrity as well as fire rating of a ceiling. Easily fitted from above or below in plasterboard or suspended ceilings. In the event of a fire, the intumescent expands to form a fire barrier, preventing fires from spreading rapidly.
According to fire statistics, overheated light fittings and electrical faults are a leading cause of fire destruction to buildings and homes. With buildings left unprotected, fire and smoke rapidly spread and destroy rooms and properties. Installing passive fire products for electrical services provides multiple benefits. Such benefits include compartmentalising fire, preventing fire spread and also preserving building structures. The intumescent material will expand to create a fire barrier, preventing fires from spreading. This allows occupants to safely evacuate a building and for fire rescue services to extinguish flames before they become severe.
Manufactured in a range of sizes to fit over various electrical fittings. An acoustic version is also available.
Tested to BS476 Parts 22, 23 and 23 (Clause 5) (1987), achieving 240minutes integrity.

Acoustic properties tested to BS EN ISO 140-3 (63dB).
APPLICATION INSTRUCTIONS
Lead the cable from the transformer through the pre-cut downlight aperture in the ceiling
Pierce the cable entry point in the top of the cover with a sharp object, creating an opening large enough to suit the cable size
Feed sufficient cable through the opening for the connection
Compress the cover and pass it through the aperture in the ceiling
Open out the cover once inside the ceiling, away from the light fitting
Using the two supplied pins, fasten opposite inner flanges of the cover to the plasterboard
Insert the light fitting and fasten the closing mechanism over the inner flaps of the downlighter cover to seal the opening
Downlighter covers require a minimum of 40mm horizontal clearance and 15mm vertical clearance
Cages are rigid and require no clearance, meaning that insulation can be packed around them as long as it does not cover the ventilation holes
NB: Downlighter cages cannot be compressed to fit through the light fitting aperture from below and must therefore be positioned from above
