Why Your Room Alert 12E Built-in Relay Behavior May Be Reversed

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.

1. To start a trace on your device, follow the instructions in this FAQ: How To Generate A Trace On A Room Alert Monitor.
2. 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.

1. To access your device’s JSON data, follow the instructions in this FAQ: Where To Find Room Alert Monitor JSON Data.
2. 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.
