Description

Fire Cages

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.


Our electrical and plumbing products meet IET wiring regulations as well as Document B & E of Building Regulations tested to European and British Standards. Browse our full range of electrical and plumbing products.

Advantages

– Maintains the fire rating of plasterboard or suspended ceilings rated up to 4 hours
– Available in standard and acoustic forms, preventing sound transfer from different floors of a building up to 63dB
– Can be made to accommodate downlighters alone, or downlighter/transformer combos
– Downlighter cages are a sturdier option, allowing for insulation to be laid over the top after they are fixed in place – ideal for lofts
– Can be used to improve the fire rating of ceiling-mounted speakers as well as downlighters
– The range also contains downlighter adaptors which can convert existing light fittings to fire resistant, low-energy units, saving up to 40W per light whilst providing 66 minutes of fire protection
– Easily installed in 5 minutes or less. Custom sizes made to order.

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

The fire cage has the same use as a downlighter cover. There are two types available: –

 

STANDARD RANGE (for standard light fittings only)

TRANSFORMER RANGE  (for light fittings including transformers)

 

The cage can only be fitted from above on fixed ceilings, and from above and below on suspended ceilings
