Page 3: Introduction
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. -
Page 4: A) Co2 Sensor Unit
The add-on module includes the PA warning unit and enables operating states to be forwarded internally as 230 V / 50 Hz or via a floating external power supply. The AM PLUS variant features a large integrated alarm light with horn and additional alarm equipment can be connected. The basic functions are identical to those of the CO2 CONTROL standard variant. Caution! -
Page 5: D) Distributor
CO2 CONTROL - assembly and operating instructions Distributor The distributor and control lines connect all of the components into a system. Switching unit The switching unit can actuate power consumption devices, such as fans or external signal devices, in the event of an alarm. -
Page 6: G) Alarm Unit
The 230 V version of the alarm unit is used to provide additional visual and audible alarms in hazard areas as well as in the entrances to hazard areas. When used in combination with the CO2 CONTROL AM version, these can be directly connected, supplied with power, and their alarms switched off directly on the add-on module. -
Page 7: System Configuration
Cooling unit In grocery stores, cold rooms, freezer rooms and machine rooms are mostly secured with CO2 CONTROL AM. Alarm and fault messages are controlled at the refrigeration control system. Alarms are acknowledged directly in a decentralised manner on the add-on module. -

Fault CO2 CONTROL AM / AM PLUS versions See CO2 CONTROL AM / AM PLUS assembly instructions 2.5 Setting the geographic height On the side of the warning unit, there is a rotary switch for setting the location height at which the detection system is installed. Ask the operator the height of the restaurant above sea level. -
Page 11: Installing The Am / Am Plus Add-On Module
CO2 CONTROL - assembly and operating instructions 2.6 Installing the AM / AM PLUS add-on module (see CO2 CONTROL AM / AM PLUS assembly instructions) 2.7 Installing the distributor The distributor housing is screwed to the wall using two screws/dowels. In order to seal the housing, the screw penetration points (1) are sealed with the included plugs. Alternatively, the distributor can also be attached to the wall using external brackets (2). -

CO2 CONTROL - assembly and operating instructions 2.8 Connecting cables to the distributor This accessory comprises four terminals (WAGO 221-415 / 5 poles) (6). There is a terminal for each wire color of the control line. The control cables can be connected to the terminals stripped in accordance with the diagram or using the standard wire end ferrule. Please ensure that the cables are only connected to cables of the same colour. -

System initialisation Once the complete gas detection system has been installed, the system must be initialised using the warning unit. For the CO2 CONTROL AM / AM PLUS versions, see the additional notes in the CO2 CONTROL AM / AM PLUS installation sheet. -
Page 14: System Check
When the sensor unit is swapped out, the gas detection system must be re-initialised (see 3.1 System initialisation and the additional notes in the CO2 CONTROL AM / AM PLUS installation sheet for the CO2 CONTROL AM / AM PLUS versions). -

4.4 Functional check A functional check (minimum requirement for the monitoring of detection devices in accordance with BGR 228) of the CO2 CONTROL is not required, and not necessary due to any maintenance replacement. Where desired, the system can be tested using CO at any time, and the alarm function checked. -

Page 18: Switching Unit
For the CO2 CONTROL AM / AM versions in a CO refrigeration equipment area, please observe the notes in the CO2 CONTROL AM / AM PLUS installation sheet! When the main alarm is triggered, no further access to the hazard area must be allowed! To eliminate the hazard, an extraction unit (where available) must be actuated or the local fire brigade must be called. -
Page 19: Warranty
Please ensure that the serial number of the installed device is entered on the postcard. KUNDOxT guarantees that the system requires no calibration and/or adjustments within 4 full years of operation. After 4 years of operation, a calibration will be performed at our plant at cost (see 4. -
