MZ3 Basic modular control panel 24 A

Compact modular standart control panel based on MZ3 for SHE and ventilation

Benefits/Features

• Compact SHE standard control panel based on MZ3
• Pre-configured at the factory and therefore ready for immediate use
• With one SHE and two ventilation groups assigned to 3 to 6 motor outputs, depending on the size of the control panel
• Standard equipped for activation by manual SHE control points, smoke detectors and fire alarm systems
• Connections for two vent switches and one wind/rain sensor
• Option for bridging both ventilation groups to form a single group
• Energy supply tested to EN 12101-10

Applications

• Natural smoke extraction (NSE)
• Natural aeration and ventilation
