SIL-1200 Commercial Kitchen Ventilation Interlock System Compliant Gas Safety Panel

Blauberg SIL-1200 Ventilation Interlock System

Gas Safety Compliance with BS 6173 for Commercial Kitchens and Catering Environments

The Blauberg SIL-1200 is an intelligent ventilation interlock system specifically engineered for commercial kitchens. It ensures safe operation by interlocking the kitchen’s mechanical ventilation system with its gas supply, preventing gas flow unless adequate airflow is verified.

The SIL-1200 is designed to help kitchens meet regulatory obligations under the British Standard BS 6173, which requires that gas appliances must not operate unless mechanical extraction is proven. Whether you're installing in a new build or retrofitting a catering facility, the SIL-1200 provides complete peace of mind and full compliance with BS 6173 and DW/172 standards.

Key Features

• Fully compliant with BS 6173:2009 – mandatory for gas appliance safety.
• BMS and Fire Alarm Integration for automatic gas isolation.
• Emergency Gas Shut-Off (local and remote)
• Fan Proving Logic to verify both extract and supply airflow.
• Real-time LED Status Indicators.
• Failsafe Gas Valve Control.
• Service Mode for controlled override during maintenance.
• Compatible with air pressure differential switches and fan current monitors.

How It Works

The SIL-1200 ensures that gas is only supplied when ventilation fans are operational, in line with BS 6173 requirements. If a fault is detected—such as fan failure, fire alarm trigger or emergency stop—the unit will cut off the gas supply immediately, helping to eliminate risks of gas leaks, asphyxiation and fire.

This is essential for:

• Gas interlock systems.
• BS 6173 compliant kitchen installations.
• Mechanical extract system monitoring.
• Fan-failure gas shutdown compliance.

Wiring and Integration Terminals:

• Power In: 100–240VAC with 3A external fuse.
• To Valve: 100–240VAC gas solenoid valve control.
• To BMS: Volt-free contacts (N/C, COM, N/O) for integration.
• EM Remote: Volt-free inputs for fire alarm and emergency buttons.
• Fan PD Switches: Inputs for both extract and supply fan proofing devices.

LED Status Indicators:

• Power: Illuminates with mains connection.
• Gas On: Green = Gas enabled, Off = Gas disabled.
• EM Stop: Amber = Emergency stop activated.
• Supply Fan: Green = Operational, Flashing = Fan not detected.
• Extract Fan: Green = Operational, Flashing = Fan not detected.
• Fan Fault: Amber = Shutdown due to ventilation failure.
• Service Mode: Green = Override active, Flashing = Timeout.

Warranty:

• 3-Year Limited Manufacturer’s Warranty.
• Covers manufacturing defects.
• Does not cover misuse or tampering.
• Replacement at manufacturer’s discretion.

Applications:

• BS 6173:2009 compliant commercial kitchens.
• Catering facilities, school kitchens, hospitals, care homes.
• Installations requiring gas interlock and ventilation monitoring.
• Environments subject to Gas Safe and DW/172 guidelines.
