Alpha Communications RCB2100SFR Refrigeration Call Box

Product Description

The ALPHA COMMUNICATIONS RCB2100SFR is a flush-mount refrigeration call box designed for 24-volt intercom systems in commercial refrigeration environments. This unit allows personnel inside walk-in coolers, freezers, or cold storage rooms to signal for assistance, supporting safety protocols in facilities where workers may become trapped or need help. The stainless steel construction resists moisture and corrosion, making it well-suited for the wet, low-temperature conditions typical of refrigerated spaces. It is installed by commercial intercom or low-voltage technicians as part of a broader facility communication or safety system.

The RCB2100SFR is intended for use in commercial and industrial refrigeration applications, including walk-in coolers, walk-in freezers, food processing facilities, cold storage warehouses, and similar environments. The flush-mount design integrates cleanly into wall surfaces, keeping the call box accessible without protruding into the work area. It operates on a standard 24-volt supply, which is common in commercial intercom and low-voltage control systems.

Key Features

• 24-volt operating voltage compatible with standard commercial intercom infrastructure
• Flush-mount form factor for clean, low-profile wall installation
• Stainless steel housing resists corrosion and moisture in refrigerated environments
• Designed for refrigeration safety applications including personnel distress signaling
• Sold as a single unit (each)

Compatibility

Designed as an OEM-style component for use within compatible ALPHA COMMUNICATIONS intercom and call systems operating at 24 volts. Verify system compatibility with your existing intercom infrastructure before installation.

Installation Notes

Installation should be performed by a licensed low-voltage or commercial intercom technician familiar with NEC requirements for communication circuits. Disconnect and de-energize the intercom system power supply before wiring or mounting the call box. The flush-mount design requires a suitable wall box or rough-in opening sized to the unit before surface finishing. Confirm polarity and voltage at the terminal connections before restoring power to the system.
