- Page 20 www.acornfiresecurity.com 2.3 Pump test Contents In the default configuration, a pumped Gas-Pro with a flow plate attached (see Fitting a flow plate page 12) will run a pump test during the start up process. A pump test will also be run whenever a flow plate is attached during normal operation.
- Page 21 www.acornfiresecurity.com 2.4 Detecting gas Contents When sampling an area that may contain water, use the ball float probe to reduce the potential for water travelling up the sample line. 2.4.1 Diffusion monitoring If you wish to monitor gases in ambient air for dangerous levels, the Gas-Pro can be worn by either clipping the strong alligator clip to clothing/overalls in the breathing zone or through the use of a chest harness.
- Page 22 www.acornfiresecurity.com 2.4.2 Pumped mode Contents Pumped operation requires the use of the pumped flow plate which automatically activates the pump (see Bump/Pump functionality page 33). Gas-Pro can either be worn or used with hoses and probes to sample from spaces prior to entry. The pump capacity in the Gas-Pro is 0.5l/m and will draw a sample of gas from 30m within 80 seconds.
- Page 23 (ie if the sample being tested is 30ppm – the expected result onscreen will show 32ppm. PC software If Gas-Pro is being used regularly for sampling, Crowcon strongly recommend the use of the internal Accessories pumped option to reduce time and potential for error.

- Page 36 www.acornfiresecurity.com 2.9.2.4 Confidence Tone Contents The Tank Check Mode confidence tone is different to other operational modes to give an audible indication of the operating mode. The Tank Check Mode confidence tone is four short ‘pips’ which are low pitch while in LEL range, and high pitch in VOL range.
- Page 37 Contents 3.1 Introduction Crowcon recommends regular gas tests (also known as bump tests) to confirm sensor operation. This involves applying a known composition of the correct gas to each sensor to verify sensor response and alarm function. Organisational specific Health and Safety regulations should be adhered to, and a number of flexible and simple solutions are available.
- Page 38 www.acornfiresecurity.com Contents From the 1st November 2010, EN60079-29 part 1 has been harmonised under the ATEX directive 94/9/EC. Therefore to comply with the ATEX directive, portable apparatus sensing flammable gases should have a functional check with gas before each day of use. Other testing regimes may be employed depending on local circumstances.
- Page 39 www.acornfiresecurity.com 3.2.1 Speedy bump Contents A speedy bump tests the Gas-Pro to first alarm level. Gas is presented across/over the sensor for a designated time (dependent on sensor gas type) during which alarm level one should be activated. This is deemed a pass if the detector goes into alarm and the detector is functioning (sounder, LED’s and vibrator, verified by the user).
- Page 40 Appendices In addition calibration should be performed as required by local or organisational regulations. In Warranty the absence of suitable evidence, such as a field assessment by a competent person, Crowcon recommend regular service and calibration every 6 months. Exit...
