The WZ-400 indicator is used to indicate the selected events in the fire alarm system by LEDs. The events may involve:

• a single detector / a single side line module:
  • alarm triggered by detector / module
  • faulty detector / module
  • disabled detector / module
• zones:
  • alarm in zone
  • faulty device in zone
  • disabled device in zone
• groups:
  • activation of group sounders
  • faulty device in group
  • disabled device in group

The indicator is designed to operate in the detection line of the ACSP-402 addressable fire alarm control panel.

• optical signaling by LEDs
• signaling controlled by the control panel:
  • capability to link the indicator with a single detector, a single side line module, zone or group
  • selection of events to be indicated
• double-sided short-circuit isolator
• powered from the detection line
