Protecta FR Service Transit, part of the Protecta Firestopping range, maintains the fire resistance of walls and floors when these are breached by continuous cables, conduits and plastic pipes, and is safe, easy and quick to install for up to 240 minutes of fire protection (integrity and insulation).

The circular high temperature plastic tube contains a graphite-based intumescent lining material which expands upon heating to seal spaces or voids around cables and pipes, preventing the passage of flames, smoke and gases for up to 240 minutes, with a plug in the middle preventing penetration of cold smoke.

Protecta FR Service Transit is classified for fire sealing all types of constructions; drywalls, masonry or concrete walls and concrete floors and can be fitted several ways; cast in concrete, friction fitted in concrete, masonry or gypsum, or inserted in larger apertures with Protecta FR Acrylic, FR Board and EX Mortar.

After installation of the Service Transit, cables and pipes can be retrofitted without having to install a new fire seal.

Available in three different lengths: 150mm, 250mm and 400mm and the selection of which to use depends on the thickness of the supporting construction and the required fire classification.

By preventing the spread of smoke and fire, lives can be saved and damage to property kept to a minimum, helping aid evacuation of personnel and giving time for emergency services to arrive and tackle the blaze. FR Service Transit intumescent cable sleeves are just a part of fire-stopping compartmentalisation, keeping fires contained in an area for a specified time and preventing them from breaching walls and floors, spreading through service holes to block emergency exits and potentially weaken structures.

Features & Benefits

• Intumescent pipe and cable sleeves
• Very high fire classifications and protection up to 240 minutes for both integrity and insulation
• Safe, easy and quick to fire stop service penetrations
• Ideal for installations where it is likely that services will be inserted or replaced later on, and for installations in tight spaces where it will be difficult to install a normal fire seal at a later stage in the building construction
• A plug in the middle prevents penetration of cold smoke
• New patented fast expanding graphite material
• For cables, plastic pipes and cables inside plastic pipes (conduits)
• Classified for fire sealing all types of constructions; drywalls, masonry or concrete walls and concrete floors
• Can be fitted several ways; cast in concrete, friction fitted in concrete, masonry or gypsum, or inserted in larger apertures with Protecta FR Acrylic, FR Board and EX Mortar
• Certified for PVC-U, PVC-C, PE, LDPE, MDPE, HDPE, ABS, SAN+PVC and PP pipes plus all kinds of cables up to a certain diameter
• No emissions - environmentally and user friendly
• Unlimited storage time (under correct conditions) with 30 years working life guarantee

Application Instructions

Refer to the Application Guide for illustrations and more detailed drawings for the following fittings:

• Empty ST’s in gypsum, masonry or concrete walls (page 2)
• ST’s with cables in gypsum, masonry or concrete walls (pages 2-3)
• ST’s with pipes etc. in gypsum, masonry or concrete walls (page 3)
• Empty ST’s in masonry or concrete walls (page 4)
• ST’s with cables in masonry or concrete walls (pages 4-5)
• ST’s with plastic pipes etc. in masonry or concrete walls (pages 5-6)
• Empty ST’s in floors (page 6)
• ST’s with cables in floors (pages 6-7)
• ST’s with plastic pipes and conduits in floors (pages 7-8)

Minimum separations and limitations: Service Transits can be fitted as specified in the detailed drawings from page 2. Friction fitted: Minimum separation between Service Transits should be at least 30 mm.

Fitted with Protecta FR Acrylic: Minimum separation between a Service Transit and the edge of the seal should be 10 mm and minimum separation between apertures should be 30 mm.

Fitted within Protecta FR Board or EX Mortar: An aperture can include several services, and they may also be different. Minimum separation between Service Transits and also between Service Transits and the edge of the aperture should be 30 mm. The minimum permitted separation between adjacent apertures is 200 mm.

Supporting constructions: Flexible walls must have a minimum thickness of 75 mm and comprise steel studs or timber studs***  lined on both faces with minimum 1 layer of 12.5 mm thick boards. Rigid walls must have a minimum thickness of 75 mm and comprise concrete, aerated concrete or masonry, with a minimum density of 650 kg/m³. Rigid floors must have a minimum thickness of 150 mm and comprise aerated concrete or concrete with a minimum density of 650 kg/m³. The supporting construction must be classified in accordance with EN 13501-2 for the required fire resistance period.

*** Timber studs: no part of the penetration seal may be closer than 100 mm to a stud, and minimum 100 mm of insulation of class A1 or A2 according to EN 13501-1 must be provided within the cavity between the penetration seal and the stud.

Installation

1. Install the Service Transit centrally in the wall, floor or fire seal ensuring that the centre point of the transit is located mid-depth in the wall, floor or fire seal

2. Friction fitted or cast installation: Make sure there is a tight seal with no gaps around the Service Transit and that it is securely locked in position. If this is not the case, simply apply a bead of Protecta ® FR Acrylic on both sides.

   Installation with Protecta FR Acrylic, FR Board or EX Mortar: Follow the Technical Data Sheet and Installation Instructions supplied with the product selected together with installation instructions and detailed drawings in this document.

3. Before cables and/or plastic pipes are inserted through the Service Transit, remove the fibre plug from the middle of the Service Transit. After the insertion of services is completed, ensure that the fibre plug is refitted and positioned correctly around the services in the middle of the Service Transit, leaving no openings so a cold smoke barrier is achieved.
4. Make sure labels with retrofit instructions are placed near the Service Transit on both sides after installation, so future service installations are completed correctly by reinstating the fibre plug.

Test Standards

This Installation Instruction is based on the product’s European Technical Assessment, issued in accordance with regulation (EU) No 305/2011, on the basis of ETAG 026-2 and 3, edition 2011, used as European Assessment Document (EAD).

Sound Insulation

The sound insulation value is only valid for the Service Transit and not for other elements in the building construction.

The sound insulation has been tested by the accredited laboratory Exova BM Trada in Great Britain according to EN ISO 10140-2. Test report is available upon request.
