Do not open the transmitter and do not replace the sensors in the transmitter in a potentially explosive atmosphere 

 

Opening the cover and replacing the sensor in the transmitter in a potentially explosive atmoshpere can cause an explosion. If 
service  is  necessary,  first  unplug  the  device  from  the  power  supply.  After  that  the  device  may  be  disassembled  and  the 
sensors may be replaced (certified partner or manufacturer). 

Do not disassemble the product and ensure against it's contact with water 

 

Contact with internal components of the product may cause an electric shock. In case of any malfuction entrust the servicing 
of  the  product  exclusively  to  a  certified  service  centre.  Contact  with  water  can  create  a  short  circuit  in  the  product  and 
consequent damange to property or personal injury. 

Use appropriate cable types 

 

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

Dispose of used products and trasmitter 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  responsivness  of  the  sensor,  checking  the 
functionality  of  the  transmitter)  and  "OPERATIONAL  AND  FUNCTIONAL  CHECKS"  of  the  entire  detenction  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 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  competance  or  the  manufacturer.  See  section  "Monitoring  the 
calibration peridos".
