Sierra Monitor Corporation Carbon Monoxide Alarm 2001 User Manual

Model 200X Series  
Gas Sensor Monitors  
Model 2001 - Combustible Gas  
Model 2003 - Hydrogen Sulfide  
Model 2006 - Carbon Monoxide  
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.  
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.  
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 warn-  
ing should the sensor fail (open circuit).  
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-  
panyingAC-to-DC power supply may be plugged into a  
standard AC source. The monitors accept 9 - 24 VDC.  
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.
