SENSOR
The TOXALERT INTERNATIONAL Model Tox-CO/ANA measures carbon monoxide concentrations
over its range of operation and provides a corresponding 4 to 20 milliamp linearized output signal.
The Model Tox-CO/ANA is the first sensor system to be priced well below laboratory type devices. This low
cost breakthrough opens a new set of applications previously unattainable. This is especially significant in
light of today’s growing concern regarding indoor air quality and increased costs of heating and cooling
energy.
The Model Tox-CO/ANA may be used in many applications. By monitoring gas concentrations, you may
control ventilation equipment and/or alarm at user defined levels of CO.
Because of potential energy savings, it is very advantageous to control the ventilation equipment of con-
fined spaces where CO is being produced (ie: enclosed parking garages, warehouses, etc.) In these types of
facilities, codes require the continuous running of ventilation equipment, unless a CO monitoring system is
employed (see background section).
The model Tox-CO/ANA supplies the carbon monoxide concentration information to any controller that
can utilize a 4 to 20 mA signal. The controller, whether automation, direct digital, or Toxalert contoller, may
be programmed to control the ventilation fans, trend log the concentrations, or alarm at user programmable
concentrations. The Tox-CO/ANA may be used with Toxalert’s Tox-4ANA’s and ToxControl analog input
controllers to digitally display the ambient CO level being sensed, operate ventilation equipment, and sound
an alarm on persistent high levels of CO. With the ToxControl controller a printer option is available to
record time and date of fan operation for each sensor, record alarm data and print out custom alarm mes-
sages.
