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.

• Microprocessor based 12 bit analog to

digital conversion resolution.

• Optional digital display for CO

level in PPM (parts per million).

• Automatic calibration.

• Selective to Carbon Monoxide.

GENERAL DESCRIPTION:

• Performance indicators

(LED’S) for:

- Power on

- System operating normally

- Automatic calibration

• UL listed components.

• Multiple ranges available.
