Control Centre RWD 2

The RWD 2 Control Centre is designed for setting up a decentralised SHEV system. For this purpose, up to 60 Control Centres can be organised in a monitored bus system with up to nine SHE groups. The decentralised arrangement allows the Control Centres to be placed close to the windows or flaps. As a result, the power cables between the Control Centre and the actuator are significantly shorter, which considerably reduces the costs for the system cabling.

To ensure that the system can still be operated centrally, the SD 2 operating unit is required as an accessory. It is connected either directly to any Control Centre or to a junction box. Via a four-line display and a keypad, it shows the status of the bus system and enables the system to be set and operated.

The RWD 2 is available in two versions: depending on the number and type of actuators, it can provide a total output current of 10 A or 20 A. Select the desired output current in the following drop-down menu.

    Description

    The SHEVS Control Centre RWD 2 is designed to set up a decentralised SHEV system in a bus system with up to 60 controls. Up to nine SHE groups with up to nine ventilation groups each can be configured. In the first SHE group, up to 19 ventilation groups are possible. Thanks to the decentralised design of the system, the distance between Control Centres and actuators is shorter, which considerably reduces the cable lengths and cross-sections.


    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.
