  • Page 13: Safety Information

    • The lid on Xgard IR must be kept tightly closed until power to the detector is isolated oth- erwise ignition of a flammable atmosphere can occur. Before removing the cover for main- tenance or calibration purposes, ensure the surrounding atmosphere is free of flammable gases or vapours.

  • Page 14: Overview

    Note: if no certification label is fitted to the junction box, the detector is not certi- fied for use in hazardous areas. Each version of Xgard IR is identified by a label fitted on the junction box body. Please quote the ‘model number’, ‘gas range’ and ‘sensor type’ when contacting Crowcon for advice or spares.

  • Page 15: Introduction

    Xgard IR is a flameproof gas detector, designed to detect hydrocarbon gases or CO Xgard IR is powered by 24 V dc (nominally) and provides a 4-20 mA signal (sink or source) proportional to the gas concentration. The detector is certified...

  • Page 16: Installation

    The following points should be noted when locating gas detectors: • To detect gases which are lighter than air, such as methane, detectors should be mounted at high level and Crowcon recommend the use of a collector cone (Part No. C01051).
  • Page 17 Xgard IR requires a dc supply of 10-30 V, at up to 100 mA. Ensure there is a minimum of 10 V at the detector, taking into account the voltage drop due to cable resistance. For example, a nominal dc supply at the control panel of 24 V has a guaranteed minimum supply of 18 V.
  • Page 18 Note: The internal grounding terminal (see diagram 4) shall be used as the grounding means of the Xgard IR gas detector. The external grounding terminal is only to be used where local authorities permit or require such a connection. Where possible, to limit radio frequency interference, the junction box and cable armour should be grounded at the control panel (safe area) only to avoid earth loops.

  • Page 19: Operation

    8. Apply calibration gas (concentration should ideally be at least 50% of full scale concentration) to the detector at a flow rate of 0.5–1 litre/minute via a flow adaptor (Part No. C03005). Contact Crowcon for the supply of calibration gas. www.acornfiresecurity.com...
  • Page 20 See the ‘Spare parts and accessories’ section for the part numbers of replacement O-rings. The sensor used in Xgard IR should provide in excess of 5 years trouble-free operation. In the event of a sensor failure, the sensor module should be replaced.
  • Page 21 Xgard IR uses a modular design, which makes replacement of sensors, or sinters extremely simple. Replacement sensors are supplied fitted to a sensor PCB to allow simple plug-in installation. An exploded view of Xgard IR is given in Diagram 3. The following procedure may be followed when servicing a Xgard IR detector.
