2.2 Sensor Installation
Only FLEXsense™ sensors provided by United Electric Controls are compatible with this device.
Do not attempt to disassemble the sensor as this could damage the sensor and void hazardous location
approvals, and manufacturer warranty.
Sensors must be activated after installation.
Ensure base unit has a sensor installed at all times when mounted outdoors to prevent damage to connectors
due to ambient moisture.
Sensors are packaged fully assembled and require simple installation into the base unit. Toxic sensors are comprised of
an electrochemical sensor packaged into a stainless steel housing. Combustible sensors are comprised of an infrared
sensor packaged into a stainless steel housing. These are consumable, field replaceable parts (see Section 4.1, Sensor
Replacement).
1. Remove FLEXsense™ sensor from packaging.
2. Retract the sensor locking pin and twist 90 degrees to lock in retracted position.
3. Align the locating pins (see Figure 9) on the FLEXsense™ sensor to the keyed positions on the sensor housing (see
Figure 10).
4. Insert the sensor. A click will be felt and heard, ensuring the sensor has been inserted correctly.
5. Twist the sensor locking pin 90 degrees and release to engage the sensor locking pin.
6. Push button to activate sensor.
For Combustible Sensor Only
7. Once the button is pushed, the base transmitter initializes the sensor activation process. During this activation, the
screen in Figure 11 will be displayed. This activation may take up to 2 minutes.
