Multiplied action mechanisms with thermal glass bulbs, for application in smoke outlets
Made of 3mm thick galvanized steel, these reduction mechanisms are compatible with 20x5mm thermal glass bulbs. Their huge multiplying coefficient reduces the force applied to the thermal glass bulb to only 15% of that applied to the mechanism. The replacement of the glass bulb is simple and can be done without special tools. They withstand the 300 DaN overload during 5 minutes, and a minimal load of 0.4 DaN.
