Liebert RCM4S Panel

The Liebert RCM4S is a professional-grade remote contact monitor designed for high-stakes environmental monitoring within data centers and industrial HVACR environments. Engineered as an OEM contact closure alarm panel, this unit provides critical oversight for up to four independent dry contact inputs, such as leak detection, UPS status, or precision cooling malfunctions. Operating on 24 VAC/DC power, the RCM4S features a Form-C common alarm relay rated at 3.0 amps, ensuring seamless integration into larger building automation systems or signaling external notification devices. Its wall-mounted chassis includes a Silence/Reset pushbutton and field-customizable labeling for each of its four red LED alarm indicators, allowing technicians to identify specific fault conditions instantly. Built for critical infrastructure, the panel supports both latching and non-latching modes, providing the flexibility needed to manage power levels and climate control alerts without unnecessary downtime.

Key Benefits

• Four-Point Monitoring: Simultaneously tracks four separate normally open (N.O.) contacts for comprehensive system visibility.
• Versatile Power Compatibility: Supports 24V AC/DC nominal voltage (+/-10%) for standard HVAC/R control circuit integration.
• Reliable Signaling: Equipped with an audible alarm and a Form-C relay output for remote monitoring and local notification.
• Simplified Installation: Features removable screw terminal connectors and standard conduit knock-outs for rapid field deployment.
• Latching Logic: Selectable hardware configuration allows for manual reset requirements, ensuring critical alarm conditions are acknowledged by personnel.

Common Questions

Can I use the RCM4S to monitor non-Liebert equipment?

Yes. While it is an OEM Liebert part, the RCM4S is designed to interface with any dry contact input, including generic sensors, leak detectors, or third-party HVAC controllers.

What is the maximum wiring distance for the contact inputs?

For optimal signal integrity, it is recommended to place the alarm panel within 300 feet (100 meters) of the signaling device using a minimum of 20AWG wiring.

Does the panel automatically reset when a fault is cleared?

The unit can be configured for automatic reset (non-latching) or manual reset (latching) via internal jumpers, depending on your facility's safety protocols.
