For your safety 

Beware of static electricity 

 

Electronic components are sensitive to static electricity. Do not touch them directly - they may get damanged. 

The device is intended to be installed by a trained person 

 

The  product  is  designed  for  installation  only  by  a  certified  technician.  The  manufacturer  is  not  liable  for  damages  resulting 
from incorrect or improper handling. 

In case of malfunction, immediately unplug from the power supply 

 

If you notice an unusual smell or smoke emitting from the product, unplug it from the power supply, battery backup and all 
other  attachments.  Continued  operation  could  result  in  injury  or  property  damage.  After  disconnecting,  have  the  device 
inspected at an authorized dealer or manufacturer. 

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

 

Opening the cover and replacing the sensor in the detector 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 

 

Detector sensors contain hazardous substances. Dispose of them in accordance with the current legislation on environmental 
protection. 

Use the detector 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 detector 

 

Perform  regular  "CALIBRATION"  (setting  the  detection  limits,  checking  the  responsivness  of  the  sensor,  checking  the 
functionality  of  the  detector)  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 detector 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 detector will transmit this fact to the host system. The detector must be calibrated immediately at 
a certified service center with a valid certificate of competance or the manufacturer. See section "Monitoring the calibration peridos".
