The 300 series Zone Display Units are transparent module directly connected to the Control Panel and requires no external power supply. The ZDU works with the 300 series detector range. When a detector goes into Alarm the panel will indicate the status. The ZDU then keeps the panel latched in alarm, and disconnects the detectors from the panel in order to communicate with them.
