Use appropriate cable types

 

 

To ensure compliance with the parameters of the product, only use the recommended cable types described in this manual. 

Dispose of used products and tra

n

smitt

e

r sensors with respect to the environment

 

 

Transmitter sensors contain hazardous substances. Dispose of them in accordance with the current legislation on 

environmental protection. 

Use the transmitter only with the appropriate certified DEGA products

 

 

The device is certified as functionally and technically qualified only with original "DEGA" accessories. In case of using the 

device with any other products the manufacturer is not liable for any damages that may occur.  

Undertake regular functional checks and calibrations of the transmitter

 

 

Perform regular "CALIBRATION" (setting the detection limits, checking the responsiveness of the  sensor, checking the 

functionality of the transmitter) and "OPERATIONAL AND FUNCTIONAL CHECKS" of the entire detection system (sensor 

excitation with subsequent control of optical and audible alarms, triggering fans, shutdown technology, etc.). Perform 

calibration and operational and functional checks only at certified service centers with a valid certificate of competence or at 

the manufacturer. 

 

Warning: The transmitter automatically checks it's calibration period - the period of validity of it's calibration. After 12 months since the 

last calibration (max. calibration period) the transmitter will transmit this fact to the host system. The transmitter must be calibrated 

immediately at a certified service center with a valid certificate of competence or  by  the manufacturer. See section "Monitoring the 

calibration periods".
