Manusa, a leading company in automatic doors and access con­trol systems has manufactured and installed three large dimen­sion tunnel partitioning doors for section II of Line 9 in Barcelona Metro.

The three identical doors, 4 me­tres wide by 3,7 metres high ap­proximately, withstand a pressure greater than 2.000 Pa and have smoke-resistant properties with a maximum resistance to fire of 120 minutes. Each door is equipped with a fire-resistant EI120 pedes­trian door to allow people pas­sage in the event of fire, when the tunnel partitioning doors will close to prevent smoke and fire spread in the tunnel.

The metal structure supporting the doors consists of a series of telescopic adjustments that al­low easy and quick adaptation to the irregularities always present in construction works, respect­ing the demanding applications required in these type of installa­tions.

Regarding control, the doors in­teract with the track signalling and the stations and tunnel fire-prevention system, meeting a SIL3 safety grade, allowing them to guarantee Siemens UTO sys­tem reliability (without driver and without conductor) that governs the circulating convoys in this metro line.

The three tunnel partitioning doors have been tailor-made manufactured under turnkey pro­ject in the record time of three months, in which Manusa has completed both fabrication and installation thanks to its techno­logical and engineering capability.
