FridgeAlert | Temperature Monitoring With Touch Screen

Engineering & Marketing International

Peace of Mind for Temperature Monitoring

  • FA100,FA100C

The FridgeAlert™ is purpose-built to monitor fridge and freezer systems. It offers smart monitoring to avoid false alarms and battery backup to continue logging temperature data while alerting of any power outages. FridgeAlert is easy to set up and features a large touchscreen display for at-a-glance information.FridgeAlert offers wireless capability with a built-in, low-power LTE-M cellular radio. Cellular models with an annual data plan include a dual SIM that provides combined coverage through AT&T and T-Mobile, automatically switching between the two for the best coverage.

  • 3.5″ Touchscreen Display
  • Up to 10 Temperature Sensors
  • 1 Digital Input
  • Cellular version available

The FridgeAlert is built for industrial-grade temperature monitoring of coolers and freezers in production facilities, warehouses, restaurants, c-stores, schools, arenas, hotels, event centers, grocery stores and more. This cloud-flexible solution keeps costs low and works with a variety of IT or industrial systems for data storage and analysis.

FridgeAlert Sensor Types

  • 10 1-Wire Temperature Sensors
  • 1 RTD Sensor
  • 1 Thermocouple
  • 1 Door Contact Sensor Input

Key Features

  • Ethernet, Wi-Fi or Cellular
  • Battery Backup
  • Logic and Alarms on Board
  • Touchscreen Display
  • Fast Setup
  • Smart Alert Notifications

Smart Alerts are perfect for typical issues in fridge/freezer monitoring:

  • Eliminate false alarms with highly customizable alert triggers
  • Custom-fit each alert to your fridge/freezer model and defrost cycle
  • Program exceptions for known restocking events
  • Save technician time

Avoid false alerts and make sure you’re only notified when there is a real concern. The FridgeAlert uses user-programmable temperature thresholds and timed delays to eliminate false alarms and quickly alert technicians as soon as a valid problem is identified.

Log Storage and History

Save your data logs onto a separate computer or server to keep an unlimited history. With an optional ControlByWeb Cloud subscription, a 30 day history is saved onto the cloud. Program your device to send log data via email or FTP.

Battery Backup Power

A 9-volt battery in the FridgeAlert allows the device to send you an alarm notification if main power is lost. It will then enter Power Save mode, where the touch screen will stay powered off. The device will continue to monitor and log temperatures for up to 5 days.

Multiple Connection Methods

The FridgeAlert can connect to the network via Wi-Fi, ethernet, or cellular (FA100C). The FA100C requires a data plan.
