When no alarms or faults exist on the SmartWireless® CXT, the Main Display will show the status of all
the sensors in the gas detection system. When the SmartWireless® CXT is in alarm, the LCD display will
stay on the channel group with the channel in alarm. If multiple alarms/faults exist, the CXT will cycle
through group pages with alarms/faults including the transceiver, RL-4/alarm station, and AO-4 group
pages. At any time the user can manually cycle to any group page using the arrow switches. After a time
out period (15 seconds), the CXT will resume page cycle protocols based upon the existence of
alarms/faults.
Four LED indicators on the front panel show alarm and fault alarm output status. The LEDs represent
ALM 1 (yellow), ALM 2 (yellow), ALM 3 (red) and FAULT (blue).

The CXT only cycles through sensor group pages when no alarms/faults exist.
