Connections and Configuration

3.2Connecting Alarm Outputs

The Zone 1 and Zone 2 alarm outputs, found in the top right corner of the Liqui-tect panel, provide a contact output for a leak and a cable break for each zone. As an example, the outputs may provide alarms to an auxiliary alarm panel or building management sys- tem. To determine the proper wire size, see Table 4 - Wiring spec- ifications.

A wiring key beside each terminal block indicates whether the con- nected output is wired for Normally Open (NO) or Normally Closed (NC).

An alarm relay wired as an unsupervised point (energized for alarm) must be wired to the Normally Open (NO) and Common (C) contacts.

An alarm relay wired as a supervised point (de-energized for alarm) must be wired to the Normally Closed (NC) and Common (C) con- tacts.

To connect an output:

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.

5.Tighten the screw until it holds the wire snugly.

3.3Connecting to a Building Maintenance System or External Alarm System

Two analog output connector blocks permit the user to connect aux- iliary notification equipment to monitor the distance of the leak and cable fault alarms. The terminal blocks are on the right side of the Liqui-tect panel printed circuit board, just above the leak detection cable connectors. To determine the proper wire size, see Table 4 - Wiring specifications.

To connect an input:

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.
