GENERAL DESCRIPTION:

The GVU-CO carbon monoxide sensor is designed

to interface with Toxalert Internationals GVU series

control. (It is not a stand alone sensor). The sensor is

microprocessor based and is temperature and humidity

compensated for stability. It has a range from 0 to 250

ppm. The transducer utilizes a tin-oxide sensing

element that is cleaned and sampled by the

microprocessor. The GVU-CO indicates its status with

a two color LED (light emitting diode). When the LED

is ﬂashing green, operation is normal and not in alarm.

When the LED is ﬂashing red, the unit is in alarm (high

CO). A continuous red or green indicates sensor failure

and an extinguished LED indicates power failure.

FEATURES:

GVU-CO

• Microprocessor based • Humidity & Temperature compensated

• Power On Indication • Sensor Failure Indicator
