DG-22.EN/M

The economical, digital detector DG.EN/M is designed for continuous monitoring of gas concentration in enclosed spaces. Upon exceeding the preset gas concentration level:

• the optical alarm signalization turns on
• the alarm information is sent via network in RS-485 standard (MODBUS RTU protocol) to the control module (e.g. MDD-256/T).

DG.EN/M has an detachable sensor module with carbon monoxide, methane, propane-butane or HFC sensor. Interchangeable sensor module streamlines maintenance, simplifies calibration and reduces operating costs.

Scope of application

• industrial area or installations individual protection
• dispersed gas detection systems
• factories, logistic centers, public buildings
• garages and underground parking - ventilation control, and warning of the LPG/CNG discharge or CO presence
• rooms at risk of excess oxygen (oxygen therapy, HFNO)

Features

• communication, control and transfer of information through the RS-485 network with MODBUS RTU protocol;
• measurement of averaged concentration of carbon monoxide or threshold detection of explosive gases;
• semiconductor gas sensor in intelligent, exchangeable module;
• built-in microprocessor control provides reliability, stability, thermal compensation system, the history of alarm events, semi-automatic address control;
• 3 or 2 alarm thresholds for CO / explosive gas;
• robust, splash-proof housing with high impact ABS (option: polycarbonate or aluminum);
• all detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 (PCA accreditation No AP150).
