Electrical Cut Off Systems.
In many cases, if a fire does occur, as well as the valve closing, an electrical signal is required to notify a BMS, close an additional solenoid valve, or set off an audible alarm.
We offer 3 kits for this eventuality:
Kit 1 contains a mercury switch which sits on the lever of the free fall fire valve, & a manual quick release.
Kit 2 contains an electro thermal link, a contactor & a knock off button. This would be used in conjunction with a solenoid valve to stop the oil flow.
Kit 3 is for outside where low voltage is required & contains an electro thermal link, a knock off button, & a panel with 24V DC PSU.
