Intumescent Downlighter Covers

Description

With the increased use of downlighters, the integrity of the plasterboard and suspended ceilings can be reduced to approximately 4 minutes protection. Envirograf® Downlighter Covers are used to restore the integrity required by British Standard Regulation requirement. The covers are available in many standard sizes, others can be made to order in approximately four days. They are easily installed in about five minutes from below or above the ceiling. With cable entries on top, the intumescent covers are ventilated to avoid light fittings overheating. For use over downlighters and speakers, etc, where the integrity of fire-rated ceilings must be maintained.

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

FIRE TEST PERFORMANCE

Tested to BS476 Parts 22 & 23, achieving up to 240 minutes 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

INTUMESCENT DOWNLIGHTER ADAPTERS

An Envirograf® retro-fitting adaptor has been developed to convert your existing downlighter fittings into low-energy units, potentially saving up to 40W per light, whilst simultaneously providing 66 minutes of fire protection. Made to order.

When ordering, please specify the original light fitting’s product name and code or send a sample of the fitting.

Low-energy lamp bulbs are not supplied with the lamp holders.

Add suffix /BC (bayonet cap) or /ES (Edison screw) to the reference for the appropriate type of fitting required.

INTUMESCENT FIRE CAGES

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
