Gas pressure proving

Merlin 2000GD Gas Proving & Ventilation Interlock - Brochure / Wiring Diagram
The Merlin 2000GD ventilation interlock & Gas Proving system. The Merlin 2000GD is for kitchens that dont have flame failure devices on the gas appliances therefore gas proving is required to meet BS 6173:2009. Monitor up to four fans using current monitors or pressure differential switches. Gas Detecors can also added if required.

Merlin 1500GD Ventilation Interlock - Brochure / Wiring Diagram
The Merlin 1500GD ventilation interlock system is designed specifically for use in commercial kitchens to meet BS6173: 2009 where kitchen appliances have full flame safeguards. Monitor up to four fans using current monitors or pressure differential switches. Gas Detecors can also added if required.

Merlin 1200S Ventilation Interlock - Brochure / Wiring Diagram
The Merlin CT1200S ventilation interlock system is designed specifically for use in commercial kitchens to meet BS6173: 2009. This system is a low cost alternative for meeting BS 6173:2009. The 1200S can monitor two fans. We can also offer a full interlock package including the valve please get in touch for further details.

Merlin 3000GD Energy Efficient Range - Brochure / Wiring Diagram
The Merlin 3000GD is an energy efficient method of interlocking the ventilation system with the gas solenoid valve. By ensuring the fans are only extracting the amount of air necessary for the amount of appliances being used the Merlin 3000GD panel minimizes the amount of heat being unnecessarily extracted from the kitchen. This provides reduced energy costs, due to reduced heat loss and fan running costs. The Merlin 3000GD also includes gas proving.

Merlin 2500GD Energy Efficient Range - Brochure / Wiring Diagram
The Merlin 2500GD is an energy efficient method of interlocking the ventilation system with the gas solenoid valve. By ensuring the fans are only extracting the amount of air necessary for the amount of appliances being used the Merlin 2500GD panel minimizes the amount of heat being unnecessarily extracted from the kitchen. This not only provides reduced energy costs, due to reduced heat loss and fan running costs.

Merlin CT1250 Ventilation Interlock - Brochure / Wiring Diagram
The Merlin CT1250 acts as an interlock between the ventilation system and the gas solenoid valve. The system has a built in power monitor which is a method used for interlocking a kitchens gas supply with the ventilation system.

PM2 Current Monitor - Brochure
The Merlin power monitor is a method used for interlocking a kitchens gas supply with the ventilation system. As an alternative to pressure differential switches the PM2 is designed to monitor the current going to a ventilation fan.

Air PD Switch - Brochure
Airflow or pressure differential switches are the most common way for interlocking with your ventilation. With easy calibration and high sensitivity our pressure differential switches are a reliable method of ventilation interlock.

Gas pressure proving

Merlin 1000GD Gas Proving System - Brochure / Wiring Diagram
The Merlin 1000GD gas pressure proving system is designed for use in School and University Laboratories. If there is a gas appliance open or a leak in the pipe work when the panel is turned on, the system will automatically detect a drop in pressure and will not allow the gas valve to open. Therefore preventing gas escaping into the classroom.

Merlin 1000GD-Plus Gas Proving & Electric System - Brochure / Wiring Diagram
The Merlin 1000GD-Plus is designed for use within a wide variety of applications including schools, colleges and university laboratories. There are many applications that gas pressure proving can be used. The Merlin 1000L-Plus system includes Key switch electrical isolation for bench sockets.

Merlin 1000GDW Plus Gas Electric & Water Control - Brochure / Wiring Diagram
The Merlin 1000GDW-Plus is designed for use within a wide variety of applications including schools, colleges and university laboratories. Not only is the Merlin 1000W-plus a gas pressure proving system but it also allows Key switch electrical isolation of bench sockets and the isolation of water solenoid valves.

Merlin CT500s Gas or Water Valve Control - Brochure / Wiring Diagram
The Merlin CT500S Safety panel is used in many applications The Merlin panel is designed to provide an effective means of isolating Gas, electricity, or water by means of a key switch on the panel, or in the event of an emergency, by operation of the emergency shut off button.

GSP-4 Four Channel Gas Detection System - Brochure / Wiring Diagram
The Merlin Gas Detection System GSP4 can be used in many applications such as factories, car parks, shopping centres and most commonly boilerhouses. The GSP4 can be used with up to four gas detectors, wiring back to the control panel is simple using four-core low voltage cable.

GSP-2 Two Zone Gas Detection System - Brochure / Wiring Diagram
The Merlin Gas Detection System GSP2 is most commonly boilerhousesor smaller commercail premisis. The GSP2 can be used with two remote gas detectors, wiring back to the control panel is simple using four-core low voltage cable for each detector.

GSP-1 Single Zone Gas Detector - Brochure / Wiring Diagram
The Merlin Gas Detection System GSP1 can be used in many applications such as factories, car parks, shopping centres and most commonly boilerhouses. The GSP1 can be used with one remote gas detector, wiring back to the control panel is simple using four-core low voltage cable.

FAB-1 Fire Alarm Bypass - Brochure / Wiring Diagram
The Merlin FAB 1 (Fire Alarm Bypass) system gives the user the ability to have use of the gas for a pre-set time whilst the fire alarm is being tested. Without a FAB-1 the Gas could be shut-off via the buildings BMS system. With prior notice to a fire alarm test, the user can turn the spring loaded key to the on position giving a un-interrupted gas supply between 10 and 45 minutes. During this time the system controlling the gas will ignore shut-off signals from the buildings fire alarm system.

CO2 Monitor & Controller (24V)
The CO2 Monitor & Controller is used to monitor room CO2 level, as well as room temperature and humidity. New building air-tightness standards that reduce air leakage into buildings can lead to a build-up of carbon dioxide in classrooms. Ventilation systems incorporating carbon dioxide monitors can be designed to provide optimum indoor air quality to keep the children awake. It provides one on/off volt-free relay output to control a ventilator with four CO2 levels preset and features both an audible alarm and a three colour backlit switching alarm display. 24V AC/DC supply voltage Three colour (green/yellow/red) LCD backlight indicating ventilation requirement based on CO2 measurement Non dispersive infrared sensing technology Volt-free relay output to control a ventilator Digital display of carbon dioxide levels (ppm) Temperature and humidity monitoring Dual alarm indication; audible alarm and backlight colour switch Easy touch button for operation Programmable setpoints.

CO2 Monitor & Controller (220V) - Brochure
The CO2 Monitor & Controller is used to monitor room CO2 level, as well as room temperature and humidity.
