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 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.
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".
