Benefits of PointGard 3100

All-in-One
The PointGard ­3100 is the optimal solution for all those who need a gas detection system but who do not want to
go through the hassle of assembling all the necessary components. It contains the measuring function of a
transmitter, the assessment function of a controller and the necessary alarm equipment, such as flashing lights and
horn.
The Application
Use the PointGard ­3700 where gas concentrations need to be monitored locally. A typical application is the
measurement of hazardous gases in unventilated or closed rooms. For this, the PointGard ­3100 is installed outside
the room at the entrance and the sensor in the room where the substance is monitored.
The Measurement Technology
Inside the PointGard ­3100, you will find the proven electronics of our Dräger ­Polytron ­8100. Our electrochemical
DrägerSensors are used for the measurement.
The Integrated Alarm Equipment
The PointGard ­3100 includes visual and audible alarms. The bright and long-lasting flashing lights warn of danger
from a distance in orange (pre-alarm)and red (main alarm). If a distinction is made between safe and unsafe
conditions, there are combinations in green (safe) and red (unsafe) or green (safe) and blue (unsafe).
The Power Supply
The PointGard ­3100 contains a 120 … 230 VAC/ 24 VDC power supply. You can also order it with a power cable
and country-specific plug as an option. If a local 24 VDC supply is already available, a variant without power supply
unit is also available.
The Operability
The measured value, gas name and measuring unit are permanently shown on the display. If required, the
concentration history of the last 15 minutes can also be shown. The display has a backlight in red or green to
ensure readability even in poor lighting conditions.
The Interfaces
In addition to the integrated alarm means, the PointGard ­3100 also has potential-free changeover relays. This
enables additional automated switching measures. Relays are available for A1, A2 and faults. Moreover, an external
switching contact, for example a fault contact of neighbouring machines, can be read in and thus the green light
(safe status) on the PointGard ­3100 can be switched off. For
