The US-3-R / US-6-R roof access switch (changeover switch, latching) is connected to the automatic detector line of a SHEVS Control Centre. When activated, the control panel's alarm function is triggered to open the SHEV. The roof domes opened as a result can then be used as roof exit. The alarm function can only be reset by turning the roof exit switch back to the off position. The domes can then only be closed manually via the ventilation button or by activating the "Auto-Close" function of the Control Centre.
Triggering and monitoring resistors are already integrated.
