THE MERLIN RANGE CT2000S SYSTEM
The Merlin 2000S ventilation interlock system is specifically designed for use in commercial kitchens to meet BS6173.
This panel is designed for use when the kitchen appliances do not have flame failure devices fitted, therefore gas proving is a requirement.
The Merlin 2000S System acts as an interlock between the ventilation system and the gas solenoid valve. The system is compatible with both current monitors and air pressure differential switches in order to interlock with up to 4 fans.
The Merlin 2000S is fitted with CO2 Mode which suits new Gas safe bulletin TB140 and allows the kitchen to have access to their gas supply for up to 24 hours in the event of a fan fault as long as they have a CO2 Monitor fitted and the air quality is at a safe level. The Merlin 2000S can also work in conjunction with natural gas, carbon monoxide and LPG sensors.

MERLIN CARBON DIOXIDE MONITOR
The Merlin CO2 Monitor is designed specifically for use in commercial kitchens and also suits Gas Safe Bulletin TB140.
The Merlin CO2 Monitor gives a LED display reading to show the user a clear and precise reading of the CO2 level in the room and also uses a traffic light colour system to show the customer whether the air quality in the room is at a safe, adequate or dangerous level.
The Merlin CO2 Monitor is 230V powered and can be used independently or can work in conjunction with one of our Merlin gas interlock systems. In the event where the CO2 levels rose to a dangerous level the Merlin CO2 Monitor would sound an audible alarm to alert the customer of the danger, and send a signal to the gas interlock system which will in turn close the gas solenoid valve.
Key Features Of the Merlin CO2 Monitor
- Clear digital readings of the CO2 levels
- Can work independently or in conjunction with Merlin Gas Interlock Systems
- Audible alarm alerts user of dangerous levels
- Can be easily wall mounted
