The unique PMA fire barrier adapters allow termination of a cable protection system to a fire wall. The adapter uses intumescent material to seal all cavities in the event of a fire and can be attached directly to the fire wall. It ensures that cables and wires can be fed through the fire barrier while retaining an E30 rating and above according to EN45545-3. These adapters are available in sizes M16 to M63 and can be adapted to any wall structure to ensure simple and safe assembly.
In the event of a fire, the intumescent material ensures that two areas remain separated from each other for at least 30 minutes (E30) in accordance with EN 45545-3. The intumescent material is fixed within the adapter to block the transport of fire, heat and fumes. The material expanding to fill the cavities between the cables within the adapter. Intumescent materials (typically sodium silicate or graphite) swell as a result of heat exposure to many times their original volume. The PMA adapter use this material very effectively to seal cavities preventing heat, fire and gases from passing through.
The Intumescent material within the PMA adapter solution blocks transport of fire heat and fumes up to 30 minutes in accordance to EN45545-3.
PMA will be showcasing various fire barrier solutions according to EN 45545 for the rail industry at the forthcoming InnoTrans 2016 exhibition in hall 15.1, stand #212
