Alpha Communications RCB2100SR Refrigerator Call Box

Product Description

The ALPHA COMMUNICATIONS RCB2100SR is a surface-mount refrigerator call box designed for use in walk-in cooler and freezer environments where workers need a reliable way to signal for assistance. Built from stainless steel, this unit is suited for cold and damp conditions typical of commercial refrigeration spaces. It operates on 24 volts, making it compatible with standard low-voltage intercom and call systems. Installers working in food service, grocery, or cold-storage facilities will find this unit appropriate for code-compliant safety communication setups in confined refrigerated areas.

This call box is intended for commercial refrigeration applications, including walk-in coolers and walk-in freezers in restaurants, grocery stores, food distribution facilities, and cold-storage warehouses. It is surface-mounted, which simplifies installation on wall panels and door frames common in these environments. The 24-volt operating voltage allows it to integrate with existing low-voltage intercom and emergency call systems already present in many commercial facilities.

Installation Notes

Installation should be performed by a licensed low-voltage or intercom technician familiar with commercial refrigeration environments. Disconnect and de-energize the call system before making any wiring connections. Ensure all conduit and wiring penetrations into refrigerated spaces are properly sealed to prevent moisture intrusion and condensation issues. Verify compliance with applicable local codes and OSHA confined-space safety requirements for worker communication systems in walk-in units.
