SmartWireless® CXT Controller
The Detcon SmartWireless® CXT controller is a multi-channel mobile gas detection control system
mounted on a tripod or a suitable stand. The CXT can be utilized as a self-contained gas detection,
display/alarm system package or wirelessly connected to the main network. The CXT is equipped with an
auto configure system to automatically search for Detcon equipment associated with the controller.
SmartWireless® CX Sensor Station
The SmartWireless® CX Sensor Station is an accessory to the SmartWireless® CXT. The CX wirelessly
transmits the data from up to 4 wired sensors back to the CXT and includes a battery that powers the radio,
alarm devices, and the attached sensors.
Alarm Stations
Alarm stations can be used as part of the gas detection system. Class I Division 1 and Class I Division 2
alarm stations are available. The stations are battery powered and controlled wirelessly by the CXT. The
strobe and horn installed on the CX are activated by the CXT when the alarms levels are reached.
Alarm options are as follows:
1. Integral audio visual mounted on the CX (Class 1; Division 2 only)
2. Standalone audio visual alarm station (Class 1; Division 2)
3. Standalone audio visual alarm station (Class 1; Division 1)
Gas Detection Sensors
Gas sensors with a 4-20mA output can be connected directly to the CX. The Model CX sensors from
Detcon are designed specifically to work with the SmartWireless® CX.

1.2 Optional Components
Options for the SmartWireless® CX Sensor Station are as follows:
 strobe
 horn
 external ‘Wet’ or ‘Dry’ alarm port
1.3 Alarms and Fault Condition
The CX Sensor Station includes an optional strobe and/or a piezoelectric horn and an external alarm
connector. The strobe is associated with Alarm 1, the horn is associated with Alarm2 and the external alarm
connector utilizes all alarm outputs (alarm 1, 2, 3 and fault) for connection to external alarm devices. The
external alarm outputs can be used to control annunciating devices or as signal inputs to other control
devices. The CX permits alarm and fault conditions to cause an assigned relay to fire, triggering external
alarm devices. When the alarm level is reached either the devices mounted to the box or attached to the
external alarm connector are activated, or both. The assigned relay outputs will return to normal state when
a gas alarm or a fault condition clears. The Alarm Relay Output can be either ‘Wet’ or ‘Dry’ determined
