Modern buildings are often equipped with lift shafts without a separate engine room. All technology is placed in the elevator shaft itself. However, this makes it necessary to provide a fire detection system in the elevator shaft. Commonly, it is often not possible or desirable to get into the elevator shaft after completion of the elevator, so that the fire detection system cannot be serviced. Another problem is that due to the moving elevator car, differences in air pressure occur, so that possible smoke will spread very unpredictably.
Because Stratos aspirating systems can be mounted in an adjacent, accessible space, commissioning and maintenance of such installations is possible without the technician having to be physically present in the elevator shaft. By mounting the aspirating pipe vertically in the elevator shaft, pressure differences due to the moving elevator car are eliminated and any smoke that may build up under the elevator car is also very quickly detected.
