r L r [1 0 n u M11C slerra monitor corporation The Model 200X Series are compact, solid- state, fixed -installation single alarm monitors designed for continuous area monitoring of Combustible Gas, Hydrogen Sulfide, or Car- bon 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 acti- vate when the concentration of gas exceeds the factory - set (and user -adjustable) level. A green LED indicator on the monitor shows that power is connected and it is a safe condition. The standard configuration has a buzzer and normally operating open relay, a fail-safe normally operating closed relay is field selectable. All the electronic circuitry needed to operate the moni- tor, except the DC input power, is contained in a com- pact unit. It may be mounted in any orientation. For a single -monitor installation and a local alarm, the accom- panying AC -to -DC power supply may be plugged into a standard AC source. The monitors accept 9 - 17 VDC. Features ■ Self -check feature signals sensor failure ■ Optional normally operating close relay ■ No chemical cells to replace, no periodic maintenace toher that routine claibration ■ All the electronic circuitry needed to operate the monitor contained compact unit, power suplly plugs into standard AC source il I I 1 9 of 0 4 - Semiconductor -Type Sensor A solid-state semiconductor -type sensor and associated electronic circuitry ensure trouble-free, long-term opera- tion. 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 installa- tion. The user may adjust the alarm level by using a different calibration gas concentration. A sensor self -check feature will flash the LEDs on and off alternatively and sound an interrupted tone as a warn- ing should the sensor fail (open circuit). Remote Alarm Available If a remote alarm is desired, the Model 2102 Dual Chan- nel Alarm Panel can be connected up to 500 feet from the monitors. Benefits ■ Reliable operation ■ Fail-safe configuration ■ Maintenace free operation ■ Quick easy installation and connection to alarm panel Sierra Monitor Corporation 1991 Tarob Court Milpitas, CA 95035 (408) 262-6611 (800) 727-4377 Fax: (408) 262-9042
