\n\n\n\n

If you purchased a Room Alert 12E in 2021, the behavior of the device’s built-in relay* may be reversed.

This means that when the device’s Status<\/em> page shows the built-in relay as ON<\/em>, its actual physical state is OFF<\/em>, and vice versa.<\/p>\n\n\n\n

* This behavior does not<\/strong> extend to external relays. If you have an external Relay Switch Sensor<\/a> connected to your Room Alert 12E through a Light Tower & Relay Adapter<\/a>, it should behave normally.<\/p>\n\n\n<\/div><\/div>\n\n\n\n

How To Check If Your Room Alert 12E Built-in Relay Behavior Is Reversed<\/h2>\n\n\n\n

One way to check if your Room Alert 12E’s relay behavior is reversed is to run a trace on the device. The beginning of the trace\u2014referred to as the “trace header”\u2014contains basic information about your device, including its PIC version.<\/p>\n\n\n\n

  1. To start a trace on your device, follow the instructions in this FAQ: How To Generate A Trace On A Room Alert Monitor<\/a>.<\/li>
  2. Once your trace begins, you should see “PIC: 0X” in the trace header.
