However, this is a preventable tragedy and the key to success is ensuring our response to impaired driving is swift, certain and significant.

  • Page 4: Physiology Of Breath Testing

    This principle is used in all breath test instruments and screening devices operated in North America, including the Alco-Sensor FST®. It should be noted that this ratio is lower than the actual ratio (2300:1) and so the results obtained through breath testing tend to underestimate the actual blood alcohol concentration.

  • Page 5: Operating Principles

    Theory and Design of the Alco-Sensor FST ® The Alco-Sensor FST® contains a fuel cell sensor and an electrically operated sampling system. A pressure sensor in the device monitors breath flow and volume to determine when to capture a breath for analysis.

  • Page 8: Conducting A Subject Test

    Each operator must confirm the next annual inspection date of the Alco-Sensor FST® prior to use. An ASD must not be used after the service expiry date (next annual inspection date) that is indicated on the tag.
  • Page 9 The sealed, rounded end should be inserted into the mouthpiece channel on the top of the Alco-Sensor FST®. In addition to the breath inlet hole, there are three additional holes in the mouthpiece. One larger hole, on top of the mouthpiece toward the sealed end of the mouthpiece, is the exit port for the subject’s breath flow.
  • Page 10 The battery strength indicator and temperature in °C (for example, 22c) will be displayed momentarily after the Alco-Sensor FST® is powered On. The battery strength indicator has 3 bars to indicate the battery strength. If the Alco-Sensor FST® does not have sufficient battery power to perform a test, either the display will not power on or “BAT”...
  • Page 11 In each of these examples, the subject is allowed three attempts to provide an adequate sample before the test is aborted with an E06 message on the display and the Alco-Sensor FST® turns itself off. Instruct the subject to provide a continuous sample with a moderate rate of breath flow. If the subject is to be given the option to attempt another breath sample (after the 3 failed attempts), it is suggested that the mouthpiece be replaced with a new one.

  • Page 12: Test Recall (Rcl)

    After the test result has been calculated the Alco-Sensor FST® will display the result for approximately 15 seconds, after which the Alco-Sensor FST® will power off. If the operator wants to review the result again, while the device is OFF, momentarily press the OFF button and the ON button at the same time.

  • Page 13: Error Messages

    Error Messages The Alco-Sensor FST® has a number of other error messages that may be displayed. If any error message is received other than E06 (improper breath sample), E09/E10 (temperature errors), E11 (blank test not successful) or E12 (RFI detection), then Authorized Service Personnel should be contacted.
  • Page 14 approved for use. For court purposes, the operator must know exactly which device and model was used and should always state that it was an “Approved Screening Device”. The sections dealing with ASD demands are listed below: Section 320.27(1)(b) – to immediately provide samples of breath into ASD , if police officer has reasonable suspicion that the suspect has alcohol in their body.
  • Page 15 the peace officer may use the results from the ASD test taken under Section 320.27(1)(b) or 320.27(2). Remember that reasonable grounds to believe a person’s ability to operate a motor vehicle is impaired by alcohol can be formed without resorting to an ASD. Where an ASD is used and the result is a “FAIL”...
  • Page 16 7. If the accused provides a “FAIL” response on the ASD, always explain to the court that you have been instructed that this means the accused's blood alcohol concentration is in excess of 100 mg% and that the accused’s ability to operate a motor vehicle is therefore impaired. This is the basis of your Reasonable and Probable grounds for an arrest.
