Except periodic calibration to verify the alarm setting, no attention is required after installation. The user may adjust the alarm level by using calibration gas with concentration equal to the alarm level. Features Model 20X Series Gas Sensor Monitors Model 201 - Combustible Gas Model 203 - Hydrogen Sulfide Model 206 - Carbon Monoxide Remote Alarm Available If a remote alarm is desired (required for 20X-00), the Model 2102 Dual ChannelAlarm Panel can be connected up to 500 feet away from the monitors. Model 201 - Combustible Gas The Model 201 can detect a wide range of combustibles. Typical applications include combustible gas monitoring in manholes, tanks, natural gas fields, parking garages and vehicle maintenance facilities, sewage treatment plants, laboratories, chemical plants, and more. Benefits ■ Explosion-proof enclosure Can operate continuously in work areas where hazardous gases could be present ■ No chemical cells to replace, no periodic Maintenance free operation maintenance required other than routine calibration ■ All the electronic circuitry needed to operate Quick easy installation and connection to alarm panel the monitor contained in a compact unit Sierra Monitor Corporation 1991 Tarob Court Milpitas, California 95035 (408) 262-6611 (800) 727-4377 Fax: (408) 262-9042 Model 203 - Hydrogen Sulfide The Model 203 can be used in such typical applications as wastewater treatment plants, laboratories and chemical plants. Model 206 - Carbon Monoxide The Model 206 Carbon Monoxide Gas Sensor Module can be used to provide an early warning of Carbon Monoxide accumulation in tanks, laboratories, chemical plants, parking garages, vehicle test facilities and more.
