The RMZ smoke detector in the Contur design supplies connected hold-open devices with 24 V DC voltage. In the event of smoke detection or an alarm, it trips the devices, thus releasing the door to close under spring power. Connections for further smoke detectors, as well as for external manual release and a floating change-over contact are also available.
