DEX-A72/N Ex

Device model: DEX-A72/N
Device type: DEX/A

DEX/A detectors are designed to detect dangerous concentrations of explosive gases indoors. They signal exceeding of two alarm thresholds (A1, A2) set in a replaceable sensor module (thresholds set at the production stage). They have a 3-wire interface type 4-20mA (passive).

DEX/A detectors are compatible with MDP or MDA type alarm modules. They can also work with any other control panels accepting the 4-20mA input line standard (and passive devices), after using the MDPL1 type power limiter (optional).

All detectors are calibrated in our own GAZEX Calibration Laboratory operating in accordance with PN-EN ISO/IEC 17025 standard (PCA accreditation no AP150).
