Product Details

Flexible, modular panel for smoke and comfort ventilation
FlexiSmoke™ WSC 520 is the smallest panel in the WSC 5xx series of modular smoke ventilation panels to control ±24V DC and MotorLink® window actuators in large and medium sized buildings e.g. shopping centres, schools or sport/leisure facilities. By linking more panels the FlexiSmoke™ is also suitable for very large buildings.

All groups in the panel have been configured in the same way which means that each group can easily be set for smoke and/or comfort ventilation.

Touch screen
FlexiSmoke™ has a build in 3½” LCD touch screen which makes it easy to configure, commission and maintain the panel – also without the need for a PC. System errors are described precisely on the touch screen to facilitate troubleshooting and initialization.

Opening speeds
 FlexiSmoke™ gives the possibility of up to three motor speeds depending of the type on motor:
 a) ±24V DC standard motor - 1 speed (H&S)
 b) MotorLink® motor - 2 speeds (H&S / manually operated)
 c) MotorLink® motor and bus communication - 3 speeds
 (H&S / manually operated / automatically)

The different speeds
 - H&S: a fast speed with H&S ventilation and security functions. (H&S always has first priority)
 - Manually operated: a faster and audible speed when manually operated by comfort ventilation
 - Automatically: a slow and almost soundless speed, when controlled automatically by comfort ventilation

Ease of cabling
The use of bus technology for the break glass units means that the need for cabling in the building is significantly reduced. The break glass unit bus are initialized directly on the panel‘s touch screen.

Smoke ventilation based on wind direction
The smoke ventilation panel can be set so that opening and closing of windows are determined by wind direction and speed. This means that facades can be utilized efficiently as part of the smoke ventilation without acquisition of additional modules aside from a wind direction sensor.

Bus communication
Comfort ventilation also possible with KNX or BACnet IP due to bus technology together with eg. NV Advance®.

Approved according to EN 12101-10 and ISO 21927-9.

The WSA 5MC KNX module is certified and listed by BACnet Interest Group Europe.

Flexible system structure
The modular smoke ventilation panel can be composed as required and it is easy to extend and reconfigure – either by adding modules or by joining several panels.
