Frequently Asked Questions
Why Your Room Alert 12E Built-in Relay Behavior May Be Reversed
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 page shows the built-in relay as ON, its actual physical state is OFF, and vice versa.
* This behavior does not extend to external relays. If you have an external Relay Switch Sensor connected to your Room Alert 12E through a Light Tower & Relay Adapter, it should behave normally.
How To Check If Your Room Alert 12E Built-in Relay Behavior Is Reversed
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—referred to as the “trace header”—contains basic information about your device, including its PIC version.
- To start a trace on your device, follow the instructions in this FAQ: How To Generate A Trace On A Room Alert Monitor.
- Once your trace begins, you should see “PIC: 0X” in the trace header.
- If your trace shows “PIC: 04” as shown in the screenshot above, then your device’s relay behavior is reversed.
- If you see “PIC: 03” or a lower value, then your device’s relay behavior is normal (not reversed).
Alternatively, you may check your Room Alert 12E’s PIC version by accessing its JSON data in your web browser.
- To access your device’s JSON data, follow the instructions in this FAQ: Where To Find Room Alert Monitor JSON Data.
- In the JSON data, you should see “picvers”:”0X.”
- If your trace shows “picvers”:”04″ as shown in the screenshot above, then your device’s relay behavior is reversed.
- If you see “picvers”:”03″ or a lower value, then your device’s relay behavior is normal (not reversed).
What To Do If Your Room Alert 12E Built-in Relay Behavior Is Reversed
If you confirm that your Room Alert 12E is running PIC v04, then you should configure your relay settings* to be the opposite of the desired behavior.
* This is true whether you are configuring your relay settings through the device’s local web interface, Room Alert Manager software, or a third party SNMP program.
- For example, if you want the built-in relay to be OFF when the device first boots up, set its Boot Profile to ON, as shown below.
- In the above example, when our device first boots up, its built-in relay will physically be off, even though the Status page will show it as On.
- Similarly, if you want the built-in relay to turn ON when an alert is triggered, set its Alarm Profile to OFF, as shown below.
- In the above example, when an alarm associated with Profile 1 gets triggered, our Room Alert 12E’s built-in relay will physically turn on, even though the Status page will show it as Off.
