Area of application
1.1
Use in accordance with BGR 228
The CO2 CONTROL gas detection system was designed in accordance with the requirements of the former TRSK 313 (Technical Requirements for Gas Detection
Devices), the current DIN6653-2 and the former TRSK 403 (Requirements for Installation, Operation and Repair), and today in accordance with BGR 228, and
complies with all statutorily required functions. However, this is only applicable to CO2 CONTROL security systems which are calibrated for 1.5% CO2 preliminary
alarm and 3% CO2 main alarm signals!
Since 07/05/1996, the legislative authority requires special protective measures in order to be able to prevent hazards due to gas leaks (Betr.Sich.V.).
A specific protective measure requires premises 1.5 m below ground level to be fitted with permanent ventilation/floor extraction, or alternatively, a gas
detection system. Walk-in cold chambers must always be secured, regardless of their installation location!
1.2
Use in refrigeration systems with CO
2
coolant
Special safety system requirements, in
CO2 CONTROL PA, CO2
CONTROL AM
and
CO2 CONTROL AM PLUS
versions, are installed for the monitoring of
refrigeration systems (DIN EN 378) with CO
2
coolant, mainly in the food trade and processing industries.
Normally, the machine room, freezers, cold chambers and partially refrigerated access ways are monitored. In supermarkets, staff rooms are also monitored
when these come into contact with the coolant lines.

System description
Method of measurement:
CO
2
is detected using an infra-red measurement system in the
sensor unit
.
System structure:
As a base system, the CO2 CONTROL basic package consists of a
sensor unit
, a
warning unit
and a
distributor
. Where multiple spaces are at risk, the system can
be expanded to include a second
sensor unit
.
Optionally, the system can also be expanded to up to 2 devices (any combination of
signal units / switching units
).
Caution! Observe the instructions in the manual!
