MC 240 universal magnetic contact with NC function and built-in resistors for a balanced loop that can be used both in alarms and access systems for monitoring e.g. doors, windows, doors and gates against unauthorized opening.
With built-in resistors, a lot of time is saved during installation with fewer connection points in the junction box and thus also fewer sources of error. You can also choose to connect the magnetic contact directly to the central unit and thus no junction box is needed. Choose between having only a parallel resistor across the reed switch or having parallel resistors and series resistors mounted with the reed switch.
