Description
The SHEVS Control Centre RWZ 5f delivers a total output current of up to 20 or 40 A as 24 V version and up to 10 or 20 A as 48 V version. It allows the configuration of one or two SHE groups and of up to four ventilation groups. The Control Centre has two signalling lines per SHE group.
Besides the detectors, ventilation buttons with indication of position and an external wind and rain control of the type WRS are connectable. As an alternative, the option WRM is available as internal wind and rain control.
General information about SHEVS and Control Centres
A smoke and heat exhaust system is an integral part of a fire protection system. Since by far the most fire victims are due to asphyxiation, smoke and heat exhaust ventilation systems make a decisive contribution to saving human lives.
The simultaneous opening of windows and flaps at the bottom and top of buildings ensures that fresh air can flow into the building at the bottom and smoke and toxic fumes can flow out of the building at the top.
Since they form part of a safety system, our products must meet the highest standards. To ensure that the system functions reliably even in the event of a mains failure, accumulators provide the emergency power supply for at least 72 hours.
Control centres form the centrepiece of a SHEV system. They offer numerous connection options for detectors, buttons, sensors and fire alarm control panels. All signalling lines are monitored for wire breakage and short circuits. The incoming signals are processed by the control centre and, depending on the configuration and programming, converted into travel commands, warning messages and fault messages.
In addition to the life-saving function in the event of a fire, our control centres, controls and actuators are also suited for the natural ventilation in buildings. For the daily opening and closing of windows, roof flaps and domelights, our actuators are designed to be particularly low-noise, maintenance-friendly and durable.
