electroniccircuitryensuretrouble-free,long-termopera-
tion. There are no pumps, filters or chemical cells to
replaceormaintain. Exceptperiodic calibration to verify
the alarm setting, no attention is required after installa-
tion. The user may adjust the alarm level by using a
differentcalibrationgas concentration.

Remote Alarm Available
Ifaremotealarm is desired, theModel2102DualChan-
nelAlarm Panel can be connected up to 500 feet from
themonitors.
TheModel 200X Seriesare compact,solid-
state,fixed-installationsinglealarmmonitors
designed for continuous area monitoring of
CombustibleGas,HydrogenSulfide,orCar-
bonMonoxide.
The Model 200X Series consists of three separate gas
monitors, Model 2001 for Combustibles Model 2003
HydrogenSulfideandModel2006forCarbonMonoxide.
Ared LED (light-emitting diode) andaudible alarmacti-
vatewhentheconcentrationof gas exceeds thefactory-
set (and user-adjustable) level. A green LED indicator
on the monitor shows that power is connected and it is
asafe condition.
The standard configuration has a buzzer and normally
operatingopenrelay,afail-safenormallyoperatingclosed
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-monitorinstallationanda local alarm,theaccom-
panyingAC-to-DCpowersupply may be plugged intoa
standardAC source. The monitors accept 9 - 24 VDC.
