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.

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 - 24 VDC.
