MD-1.A/T

Control Unit type MD-1.A/T is designed to work with gas detector types DEX/F, DG/F or DG.EN produced by GAZEX. It is used to build large Gas Detection Systems.

Application scope

• local toxic, oxygen or explosive gas detection systems
• individual protection installations in individual areas
• dispersed gas detection systems

Features

• one gas detector input for DEX/F, DG/F or DG.EN type (power supply with current limitation and connection control)
• status control of the wired connection to the detector (signals interruption of any wire)
• visual alarm states and control outputs (without memory)
• A1, A2 – 12 V DC alarm outputs for the external signaling devices
• separated relay outputs (one for each threshold) for the external signaling devices or fans steering
• case for mounting in standard cabinets (35mm DIN rail)
• outputs functionally compatible with control units outputs type MD-2 (4,8,16) (but no FAILURE output and no remote control input)
• 12 V DC supply (with LED signalization)
