6.5 Setup System - Setup Alarm Outputs
The Liqui-tect panel has six alarm outputs—three types for each zone:
• Digital alarm output for cable break detection - a change in state indicates a broken cable or con-
tamination on the cable
• Digital alarm output for leak detection - a change in state indicates a leak on the cable
• Analog alarm output for 4-20mA - the signal may indicate normal operation, the location of a
leak, a cable break or contamination
These outputs may have a wide variety of Liebert or other manufacturers’ equipment connected to
receive alarm notification.
To configure all alarm outputs:
Log In and Choose Setup System
• From the Main Menu, use the arrows ↑↓ to choose System and
Control, then press Enter ↵ (see 6.1 - Login for help) .
• Enter your password at the Login screen.
• From the System and Control Menu, use the arrows
↑↓ to choose
Setup System, then press Enter ↵ .
Select Setup Alarm Outputs
• From the Setup System Menu, shown at right, use the arrows ↑↓ to
choose Setup Alarm Outputs and press Enter ↵ .
Table 9 shows alarm output features and their default settings: you
may specify the maximum cable length of analog alarm outputs, define
digital alarm output relays as Normally Open or Closed, and set up
alarms as Latched or Unlatched.
To change the default settings, use the steps following Table 9.
