Ground Connections Effective grounding is crucial to ensure stable Modbus communications and to limit the effects of radio frequency interference. Ground points are provided inside the back box. In order to prevent false readings or alarms as a result of ground loops, ensure that the shield of all cables are grounded at a single point, preferably at the controller.

Insert 50mm length of supplied adaptor flexible tubes to interface the inlet and outlet ports of the Calibration/Flow Cap to the VEA tubes. Ensure the flexible tubes are inserted over the full length of the nozzles.

  • Page 23: Commissioning

    Commissioning Note: The VESDA Sensepoint XCL gas detector is supplied from the factory pre-calibrated. However, it is strongly recommended that the detector response is checked and if necessary, re-calibrated before placing it into service. Refer to Calibration for details on the correct calibration procedure.

    6. Remove power and refit the detector module to the back box. 7. Apply power. The VESDA Sensepoint XCL will enter a warm-up mode during which time the status indicator will be steady yellow and the output (mA version) will be held in an inhibited state.
  • Page 25 VESDA by Xtralis VESDA Sensepoint XCL Installation Manual Inhibited: The indicator is on steady yellow when the user has placed the detector into the inhibit state for maintenance or repair. Alarm: The indicator flashes red when the gas concentration is beyond the alarm-level threshold.

  • Page 26: Maintenance

    Using the Control Buttons It is possible to perform basic maintenance functions on the VESDA Sensepoint XCL gas detector without the use of the mobile app. This is achieved through the use of two control buttons inside the detector. Familiarize yourself fully on the operation of these buttons before attempting to use them.

    4. Connect smartphone to the VESDA Sensepoint XCL detector via Bluetooth. 5. Place the VESDA Sensepoint XCL detector in inhibit mode by using the inhibit control on the mobile app. 6. Attach 100m (328ft) 4mm ID (0.16in ID) tube or equivalent reduced diameter tube length upstream the VESDA Sensepoint XCL Calibration/Flow Cap.

  • Page 30: Replacing The Sensor

    Attempting to use non-genuine sensors could result in malfunction of the product. CAUTION: Do not replace the sensor without first a) removing power to the VESDA Sensepoint XCL or b) placing the sensor into the sensor maintenance mode. 1. Disable the VEA smoke detector, disconnect both flexible tubes from the Calibration/Flow Cap nozzles and remove Cap.
