Some AcuRite Weather Stations, and Multi-Sensor Stations feature Programmable Alarms that sound an alert to notify you when a value (for temperature, humidity, etc.) has been reached or exceeded. When an alarm is triggered, the display unit emits an audible beep and some units show flashing data or an icon in the affected category. You can customize the alarms by turning ON or OFF the alarms you'd like activated or deactivated, and most alarms allow you to input your own values to trigger the alarm.
Some of the alarms that may be included with a product are listed below. For the complete list of alarms included with a particular model, please read the user manual for the product.
