Vertiv WSCK-10 10ft Dry Contact Leak Detection Sensor

Overview

The Vertiv WSCK-10 is a 10-foot (3-meter) dry contact leak detection sensor designed to extend water intrusion monitoring reach in data centers, server rooms, and critical infrastructure environments. When fluid reaches the sensing cable, the dry contact output changes state — triggering an alert through whatever monitoring appliance or environmental management unit it's wired into. If you're running a raised-floor data hall, a UPS battery room, or a mechanical room adjacent to CRAC/CRAH units, a water event that goes undetected for even a few minutes can cascade into hardware loss measured in six figures. The WSCK-10 exists to prevent that.

This sensor fits squarely into the Vertiv environmental monitoring ecosystem, pairing with Vertiv Liebert and Geist monitoring units that accept dry contact inputs. If you're already deploying Vertiv infrastructure management hardware, the WSCK-10 drops into that architecture without requiring additional protocol translation or software licensing.

Key Features

• 10ft (3m) Sensing Cable: The WSCK-10's full 10-foot reach lets you run the sensor cable along the perimeter of a raised-floor panel, under a CRAC unit, or across the width of a battery cabinet room — covering the linear run where water first collects before it spreads. A shorter sensor forces you to guess the highest-risk spot; 10 feet gives you coverage across a realistic leak path.
• Dry Contact Output: The sensor uses a simple dry contact interface — no proprietary protocol, no powered transducer, no firmware. That means it wires directly into the dry contact input terminals found on virtually every environmental monitoring unit, PDU with sensor ports, or building management system relay input. If the monitoring appliance has a contact closure input, this sensor speaks its language natively.
• Passive, Low-Maintenance Design: Dry contact sensors carry no active electronics at the sensing end. There's nothing to calibrate, no batteries to replace, and no firmware to update in the cable itself. Once installed and confirmed functional, the sensor requires essentially zero ongoing maintenance — appropriate for a device you're depending on in an unmanned equipment room.
• Vertiv Ecosystem Integration: Deployed within a Vertiv monitoring environment — Liebert SiteScan, Geist rPDUs with sensor ports, or Vertiv Avocent appliances with environmental inputs — the WSCK-10 integrates without adapter hardware. Alarm thresholds, notification routing, and alert escalation are handled at the monitoring unit level, not in the sensor itself.
• Physical Reach for Under-Floor Runs: In a raised-floor data center, water that enters from a pipe leak or condensation drip pools at the subfloor — often out of sight until it wicks up to tile level. A 3-meter cable routes from a wall-mounted monitoring port down through a tile cutout and across the subfloor surface, covering the horizontal distance where that water actually sits.
• Compatibility with Third-Party Dry Contact Inputs: Because the output is a standard dry contact closure, the WSCK-10 isn't limited to Vertiv equipment. BACnet controllers, Modbus relay modules, and third-party DCIM platforms with contact input expansion cards can all accept this sensor — useful in hybrid-vendor environments where the monitoring layer isn't exclusively Vertiv.

Integration and Compatibility

The WSCK-10 connects to any monitoring device or controller with a dry contact input terminal block. Within the environmental monitoring product family, it pairs with Vertiv Geist rack PDUs and environmental monitoring units that include dedicated sensor ports. Outside the Vertiv stack, it is compatible with building automation systems, third-party DCIM platforms, and BMS relay input cards that accept normally-open or normally-closed dry contact signals.

For data centers running a structured power and infrastructure management architecture, the WSCK-10 feeds water event alerts upstream into the same notification chain as temperature, humidity, and power alarms — giving the operations team a single pane of glass for all environmental exceptions. If you're planning a larger sensor deployment across multiple racks or zones, consider pairing with a managed network switch infrastructure that supports your monitoring unit's IP connectivity requirements.

Installers working in data center infrastructure projects should note that the sensor's dry contact output is polarity-agnostic on most monitoring inputs, but confirm your specific monitoring unit's wiring diagram before termination — some units distinguish NO from NC on the input terminal and require a specific wiring orientation to alarm correctly on a wet event versus a cable-cut fault.

Frequently Asked Questions

Q: What type of output does the WSCK-10 use, and what monitoring equipment is it compatible with?

A: The WSCK-10 uses a dry contact output — a simple contact closure with no active electronics or proprietary protocol. It is compatible with any monitoring unit, PDU, BMS controller, or DCIM appliance that accepts a dry contact input, including Vertiv Liebert and Geist monitoring hardware as well as third-party building automation systems.

Q: How long is the sensing cable on the WSCK-10?

A: The WSCK-10 sensing cable is 10 feet (3 meters) in length. This gives enough reach to run the sensor under a raised floor panel, along the perimeter of a CRAC unit drain tray, or across the floor of a UPS battery room.

Q: Does the WSCK-10 require any configuration or firmware updates?

A: No. The WSCK-10 is a passive dry contact sensor with no active electronics in the cable. There is no firmware, no calibration, and no software configuration required at the sensor level. Alert thresholds and notification logic are configured in the connected monitoring appliance, not in the sensor itself.

Q: Can the WSCK-10 be used with non-Vertiv monitoring systems?

A: Yes. Because it outputs a standard dry contact closure, the WSCK-10 is not restricted to Vertiv equipment. It can connect to third-party DCIM platforms, BACnet or Modbus relay modules, and any building management system with a contact input terminal — making it useful in mixed-vendor infrastructure environments.

Q: What is the WSCK-10 (often searched as WSCK 10) best used for?

A: The WSCK-10 is designed for water leak detection in critical infrastructure environments: raised-floor data centers, server rooms, UPS battery rooms, and mechanical spaces adjacent to cooling equipment. The 10-foot cable covers the horizontal distance where water pools at subfloor level before it becomes visible at floor tile height.

Q: Where should the WSCK-10 sensor cable be physically positioned for best coverage?

A: Position the sensing cable at the lowest point of the monitored area — the subfloor surface in a raised-floor environment, along the drain path under a CRAC or CRAH unit, or at the base of a battery rack. Water follows gravity, so the cable should intercept it at the first collection point, not at tile level where it would already be spreading.

Jerry Tildsen

I've specified the WSCK-10 on a number of data center build-outs specifically because its dry contact output removes the integration question from the conversation entirely. Every monitoring appliance I've encountered — Vertiv or otherwise — has a contact closure input, and that universality is genuinely useful when you're commissioning a mixed-vendor infrastructure and don't want sensor compatibility to become a procurement issue.

Technical Highlights:

• 10ft (3m) Cable Length: Three meters is long enough to run from a wall-mounted monitoring port through a floor tile cutout and across a typical subfloor bay — covering the water collection zone without requiring an extension or a second sensor drop point.
• Dry Contact Interface: No powered transducer, no driver, no protocol stack. The contact closure wires directly to the terminal block on the monitoring unit. Integration time is measured in minutes, not hours.
• Passive Sensor Architecture: Nothing in the cable degrades, calibrates out, or needs a firmware cycle. In an unmanned equipment room, that passive reliability matters more than any feature list.

Deployment Considerations:

• Confirm whether your monitoring unit's contact input is configured to alarm on open or closed state before terminating the sensor — an inverted alarm logic configuration will suppress the alert on a real leak event rather than trigger it.
• The WSCK-10 detects water at the cable surface only — it does not report location along the cable. If pinpointing the leak source matters for your facility, a zone-based leak detection rope system is the appropriate upgrade path.

For a raised-floor colocation environment where a chilled-water pipe or CRAC condensate leak could reach server equipment before staff notice, the WSCK-10 deployed at each floor bay under cooling infrastructure is the lowest-friction way to close that monitoring gap.
