Enhance Safety and Save Energy with Advanced Door Monitoring
The Modularm® DAC-55™ is a robust refrigerator and freezer door alarm and monitoring system engineered for OEMs who need reliability, efficiency, and safety in commercial kitchen environments.
Designed for walk-in coolers and freezers, the DAC-55 not only provides visual and audible alarms to ensure doors are not left ajar but also integrates seamlessly with refrigeration systems.
This unit actively reduces coil icing, improves energy efficiency, lowers maintenance costs, and protects stored products by maintaining proper temperatures. For enhanced safety, the DAC-55 supports an optional IP-1 Illuminated Pushbutton that doubles as a panic/entrapment alarm for personnel working inside compartments.
With user-selectable configurations, field-adjustable alarm delays, and automatic control of lights, fans, and solenoids, the DAC-55 replaces conventional switches and transforms walk-in cooler/freezer safety and energy management.
ETL-listed and tested in leading retail chains, it is a proven solution for OEMs requiring durability, compliance, and long-term value.

Refrigeration Control: Automatic fan and solenoid shutoff with user-selectable timing reduces energy waste and equipment wear.
Entrapment Safety: Optional add-on IP-1 Pushbutton provides panic/entrapment alarms for personnel protection.
Lighting Automation: Automatically controls compartment lights, eliminating the need for separate switches.
Field-Adjustable Settings: Door ajar delay (5–45 minutes) and refrigeration shutoff pre-delay (1–120 seconds) to match manufacturer application needs.
ETL Listed: Safety and performance compliance for commercial refrigeration applications.
Optional Accessories & Compatible Products
The 75LCT Touchscreen Multi-Monitor safeguards perishables with alarms for temperature fluctuations, power outages, and door-ajar.
The 75LC Multi-Monitor for walk-in coolers & freezers saves energy & maintenance costs, protects perishables, and increases operator safety.
The IP-1 Illuminated Push Button Panic/Entrapment Alarm provides light control and auto-panic from inside the unit to ensure employee safety.
Benefits of the DAC-55™ Door Alarm Monitor
Lower Energy Costs: Reduces compressor run-time and unnecessary light usage.
Improved Product Integrity: Maintains consistent temperatures, minimizing spoilage and ensuring consistency.
Reduced Maintenance: Decreases coil icing and system wear for longer equipment life.
Faster ROI: Case studies show dramatic reductions in door-open hours, leading to measurable cost savings.
Challenges the DAC-55™ Helps Solve
Energy Waste
Doors left ajar lead to skyrocketing energy costs. The DAC-55 reduces open-door time by up to 85% in pilot tests, directly lowering utility bills.
Coil Icing
Uncontrolled airflow causes icing and downtime. The DAC-55 reduces icing by managing fans and solenoids during door-open conditions.
Equipment Wear
Excessive compressor cycling shortens equipment life. Adjustable refrigeration shutoff delays reduce unnecessary cycling and increase lifespan.
