Abstract

The invention relates to an aerosol can containing a mixture of carbon dioxide and nitrogen gas. This aerosol is used for testing carbon monoxide detectors.

Description

2342097 Page 1 CARBON MONOOME DETECTOR TEST AEROSOL The invention relates
to an aerosol type can in various sizes containing a gas mixture to test the function and performance of carbon monoxide detectors.
Carbon monoxide detectors for domestic use have been available for approximately five years to the time of this application.
Such devices have a life expectancy of five years due to the gradual deterioration of the sensor incorporated in each device.
Unlike the situation with smoke alarms there is not a readily available source of carbon monoxide available to test that the device is still ftmetioning in accordance with manufacturers specification.
The object of the invention is to provide a source of carbon monoxide to test such devices.
The percentage of carbon monoxide in nitrogen is critical. Too high and it would destroy the sensor embodied in the device by over contamination as well as create a hazardous product for the consumer. Too low and it would not be sufficient to make the device alarm.
The mixture of gas will be 1% carbon monoxide in nitrogen. This is not a hazardous mixture for general consumer use but sufficient to cause carbon monoxide detectors manufactured to BS 7860 1996 to go into alarm mode with detriment to the sensor.
The gas will be packaged in a variety of canisters, typically 75 mI for private domestic use and 500 mI for use by plumbers, gas service engineers etc.

Claims (2)

1. An aerosol can containing a mixture of carbon monoxide and nitrogen gas used for testing carbon monoxide detectors.
2. The concentration of carbon monoxide in nitrogen, as claimed in claim 1, to be at a specified concentration to allow the device under test to alarm but to non destructively test the sensor.
