2. Unscrew the two screws (where the black arrows are) and remove the plastic cover in a direction towards you 3A. Assembly of the detector directly to the wall (without utilising the DEGA KD mounting plate) The uncovered base can be installed, using a pair of dowels or screws, at the location recommended in accordance with the type of gas detected.
Page 13 3B. Assembly of the detector on the mounting plate. Remove the spanner from the central part of the mounting plate and retain it (you will need it for the disassembly of the detector); using four screws or dowels, attach the mounting plate in accordance with the type of gas detected and install the detector onto the mounting plate.

6. Attach the connector in the upper part and slide it to the central part. The assembly of the compact detector is then completed. Disassembly of the detector In the variant that does not require using the mounting plate (DEGA KD) Disconnect all the cables and then dismantle the transmitter by unscrewing the lower part of the DEGA05 from the wall.
Page 16: Sending The Detector For The Calibration
Sending the detector for CALIBRATION At least once a year it is necessary to calibrate the detector and, in the case of choosing the calibration of the detector without any physical intervention in the area of its application, it will be necessary to send the detector to the manufacturer or to an authorised service centre for calibration.
Page 17: Functions Of The Compact Detector
The compact detector remains in this mode during most of its operation. The information displayed on the LCD display is related primarily to the actual sensor that is inside the compact detector. If the external DEGA NBx-yL II transmitter is installed, displaying data from it, can be achieved by pressing .
Page 18: Detection Of Critical Temperatures
EXTERNAL GAS DETECTION TRANSMITTER One external transmitter of the DEGA NBX-yL II type can be connected to a device, communicating through an analogue 4-20 mA current loop. When purchasing a compact detector with an additional transmitter the function of the additional sensor is activated and the “[CHANNEL]”...
Page 19: Operation
THE STATUS OF THE REQUIRED SERVICE INTERVENTION (CALIBRATION OF TRANSMITTERS) The compact detector is provided with automatic monitoring of the calibration periods of the gas transmitters. Following the expiration of 12 months since the last calibration of the internal transmitter or the external sensor the user is alerted to the necessity of recalibration.
