Kingspan STG module control unit MZ3 Basic 32 A

Compact modular standard control center based on the MZ3 for RWA and ventilation

• Compact RWA standard control center based on the MZ3
• Features Preconfigured at the factory, meaning it can be used directly in the field
• With one RWA and two ventilation groups, depending on the size of the control center
• divided into 3 motor outputs
• Equipped as standard for activation by RWA control points, smoke detectors and BMA systems
• Connections for two ventilation buttons and a wind/rain detector
• If necessary, the two ventilation groups can be combined into one group by setting a bridge
• Energy supply tested according to EN 12101-10

Areas of application:

• Natural smoke extraction (NRA)
• Natural ventilation and ventilation
