Model 200X Series
Gas Sensor Monitors
Model 2001 - Combustible Gas
Model 2003 - Hydrogen Sulfide
Model 2006 - Carbon Monoxide
The Model 200X Series are compact, solidstate, fixed-installation single alarm monitors designed for continuous area monitoring of
Combustible Gas, Hydrogen Sulfide, or Carbon Monoxide.
The Model 200X Series consists of three separate gas monitors, Model 2001 for Combustibles Model 2003
Hydrogen Sulfide and Model 2006 for Carbon Monoxide.
A red LED (light-emitting diode) and audible alarm activate when the concentration of gas exceeds the factoryset (and user-adjustable) level. A green LED indicator on the monitor shows that power is connected and it is a safe condition.
Semiconductor-Type Sensor
The standard configuration has a buzzer and normally operating open relay, a fail-safe normally operating closed relay is field selectable.
A sensor self-check feature will flash the LEDs on and off alternatively and sound an interrupted tone as a warning should the sensor fail (open circuit).
All the electronic circuitry needed to operate the monitor, except the DC input power, is contained in a compact unit. It may be mounted in any orientation. For a single-monitor installation and a local alarm, the accompanying AC-to-DC power supply may be plugged into a standard AC source. The monitors accept 9 - 24 VDC.
A solid-state semiconductor-type sensor and associated electronic circuitry ensure trouble-free, long-term operation. There are no pumps, filters or chemical cells to replace or maintain. Except periodic calibration to verify the alarm setting, no attention is required after installation. The user may adjust the alarm level by using a different calibration gas concentration.
Remote Alarm Available
If a remote alarm is desired, the Model 2102 Dual Channel Alarm Panel can be connected up to 500 feet from the monitors.

Model 2001 Combustibles Gas Monitor
The Model 2001 can detect a wide range of combustibles. Typical applications include combustible gas monitoring in basements near waste dumps, manhole, tanks, parking garages and vehicle maintenance facilities, laboratories, chemical plants, and more.
Model 2003 Hydrogen Sulfide Monitor
The Model 2003 can be used in such typical applications as waste water treatment plants, laboratories and chemical plants.
Gas Sensor Monitors
Model 2006 Carbon Monoxide Monitor
The Model 2006 Carbon Monoxide Gas Sensor Module can be used to provide an early warning of CO accumulation in tanks, laboratories, chemical plants, parking garages, vehicle test facilities and more.
