The detector is intended for use exclusively in a non-explosive environment
Detectors DEGA NSx-yL II (ZONE 2) and NSx-yL III (ZONE 1) are designed for use in potentially explosive environment.
Do not disassemble the product and ensure against the contact of its internal components with water
Contact of internal components of the product with water may cause an electric shock. In case of any malfunction 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 damage to property or personal injury.
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 detector 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 responsiveness of the sensor, checking the
functionality of the detector) 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 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 competence or by the manufacturer. See section "Monitoring the calibration periods".
