- The THM 440 has a spark suppression diode (free-wheeling diode) to protect switching elements against premature burnup or overvoltage peaks and a reverse polarity protection diode
Notice
Magnetic door holders are used as locking devices to hold open movable room partitions such as fire protection doors, smoke protection doors and other partitions. They must be linked to a smoke detection system which switches off the holding current in the event of a fire to close the door and prevent the spread of fire and smoke.
