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. When the fan is turned on the PM2 monitors the electrical current going to the fan motor, when there is sufficient current going to the fan monitor the PM2 sends a signal back to the Merlin system indicating the fan is running. Gas can now be introduced into the kitchen.
The Merlin PM2 carries a 3 Year OGS warranty and is fully supported by our technical team.
