3.4 RS422 SiteScan Web Connector
The Liqui-tect panel will interface with Liebert’s SiteScan Web enterprise
monitoring system. SiteScan can be used to monitor the Liqui-tect panel from
a host computer and silence the audible alarm. The terminal block connector,
TB8, is on the bottom edge of the board, near the left corner.
To connect the SiteScan Web to the Liqui-tect panel:
1. Disconnect electrical power to the Liqui-tect panel.
2. If necessary, remove a conduit knockout to permit wire entry into the
Liqui-tect panel enclosure.
3. Bring the wire(s) into the Liqui-tect panel enclosure through a conduit
knockout or access slot.
4. Loosen the appropriate screw and slip the stripped end of the wire into the
terminal block. Note that the wires are polarity sensitive.
5. Tighten the screw until it holds the wire snugly.
3.5 Disable the Audible Horn
The panel’s audible horn is enabled by default. You may disable it as follows:
1. Set DIP switch 1, the first switch, to the ON position (up) to disable the audible horn.
2. Press the reset button to initiate the change.
To re-enable the horn, set DIP switch 1, the first switch, to the OFF position (down) and press the
reset button.
