Ventlux Orange MCP Fireman switch for use with SVM, BTR, D&H, WindowMaster & Ferralux controllers (SVM only for smoke input)

The VSK321 was designed for easy installation in standard smoke control systems. The 
possibility of including the smoke detector connections from the call point also provide a more advanced scenario than most other systems.
No special key or tool required for gaining access to the call point for periodic service and 
maintenance testing, making this a more convenient product for service engineers for the future. Easy installation with clear marked connections, and numbering to match the SVM24 control panel.
