3.4 Status LED
3.4.1 RS485-TX/RX:
When the QIRF is connected to a Controller System through RS-485, the traffic of the
communication can be monitored visually through the two RS-485 indicators. One is RX
LED, which indicates the data stream received in the Controller. The other is TX LED,
which indicates the data stream out of the QIRF.
Note: If the TX LED or the RX LED is always ON, that means the communication
has a problem. See Troubleshooting for RS-485.
3.4.2 Relay1-3 LED:
Indicate the status of each relay. When the relay is actuated/closed, the Relay LED is ON.
When the relay is de-actuated/open, the relay LED is OFF.
Note: If you set the relay to be Normally Energized Relay (Fail Safe), the relay LED
will turn ON at non-alarm state and turn OFF at alarm state, because the LED
reflects the relay coil status.
3.5 Latched Relay Reset
To acknowledge a latched condition, press Key [ESC] for 3 seconds. All latched relays
for which the alarm condition has been removed will reset. If the alarm condition (e.g.
high gas concentration) is still present the relay(s) will not reset.

Press Key [ESC] to silence the buzzer and horn. Press the Key [ESC] again to remove the
