7.3 General connection of alarm detectors "Z-wiring"
Z-contacts → Detectors that are powered by an external voltage source and are looped into the detector
group using a zero potential relay contact, and simple contacts without external power supply,
e.g. magnetic contacts.
Z-Sensors → Detectors that draw their supply voltage from the voltage of the detector group.
When a detector is activated, the detector group voltage is loaded such that the control panel
can carry out an evaluation.
