Feature description

The versions of the Dräger PointGard 2000 product family are
stand-alone gas detection systems. Alarm conditions are
indicated by the built-in alarm devices. 2 versions of strobe
combinations are available.
– Amber and red strobes
The amber strobe indicates pre-alarm A1. The red strobe
indicates main alarm A2.
– Green status light and red strobe
The green status light turns off in a fault or alarm
condition. The red strobe indicates the main alarm A2 and
the pre-alarm A1.
An analog 4-20mA output allows the instrument to
communicate with a control unit. The instruments are
available with a DC or AC power supply. Gas concentrations,
status messages, and menu choices are displayed on a
backlit graphic LC-display and 3 colored LEDs. The backlight
color can be switched to red or green.
Alarm patterns of integrated alarm devices, such as flashing
modes of the strobes and horn tones, can be configured with
a DIP switch. The instruments can be equipped with dongles:
– Sensor test dongle activates the sensor self-test (only for
certain sensors)
– Diagnostic dongle activates the sensor self-test, the
display of the sensor vitality, and the sensor diagnostic
functions (only for certain sensors and functions)
3.3.1 PointGard 2100 EC
The instrument monitors concentrations of toxic gases or
oxygen in ambient air depending on the installed sensor. The
EC sensor has to be ordered separately and installed. An EC
remote sensor enclosure with a cable up to 100 feet (30m)
can be ordered as an accessory.
3.3.2 PointGard 2200 CAT
The instrument monitors concentrations of combustible gases
and vapors in ambient air depending on the installed sensor.
2 PointGard 2200 versions are available:
– With an already installed CatEx sensor
– CatEx remote for remote applications together with a
