Acorn Controls Automatic Temperature Monitor
February 28, 2022
The Acorn Controls Automatic Temperature Monitor (ATM) is a microprocessor based controller ideal for sensing and alerting of abnormal temperature conditions. Target applications for this device are in health care and nursing facilities but can be used anywhere a temperature alarm is required. The ATM is factory preset as a high temperature alarm adjustable between 60 and 180 degrees Fahrenheit. It also provides two levels of alarm modes: The first provides a visual indication that temperature is above the normal limit (but not yet considered unsafe), and the second provides an additional audible buzzer warning of a potentially unsafe condition.
