MBAS 9900 Alarm Annunciator

Introduction: It is a Audio Visual Alarm Annunciator. It is best suitable for Control Panels & Switchboards of Diesel Powered Generators, AMF Controllers with trip interlocks, Engine driven Compressors, Fire Fighting Pumps etc. It functions as a complete Annunciator with Control Function to monitor Alarm conditions with both Audio Visual indications. It senses the 12V DC or 24V DC potential contacts & offers output trip contacts for interlocking purpose. It has a built in audible devise. Acknowledged & Reset by built-in push buttons. It consists of 3 basic sections (The Power Pack, The CPU & The Facia) but with an exception that unlike the conventional Annunciators the CPU card accepts 12V DC or 24V DC potential contacts as fault inputs instead of potential free contacts.

Features: · Powerful Microprocessor Circuit. · For 4,6,8 windows (faults) · Fully Integrated Construction. · Built-in System Watchdog LED. · Optically isolated input circuit. · 12V / 24V DC Potential Contact Inputs. · 2 CO Trip Relay Output. · Operates on 24V DC Auxiliary supply. · Built-in Push Buttons (NA for 8 Pt.Model) · Built in Buzzer · Super Bright LED’s · Lower Power Consumption. · AC / DC Auxiliary Supply. · Manual Reset · Auto Reset.

Application Areas: Firstly, where Electrical Control Circuits work on + 24 V dc supply. MBAS 9900 operates on 24V dc supply. Secondly, where the user has to monitor following Alarm conditions with both Audio & Visual indications. Lube. Oil Temperature Lube. Oil Pressure Gen. Over Speed Jacket Water Temperature High Low Fuel Level Spare MBAS 9900 is available in 4 or 6 window configuration which meets the Requirement. Thirdly, where volt free contacts are not available & separate auxiliary relays, control relays are required which adds to the costs. MBAS 9900 accepts + 24V dc contacts directly from the control circuit. Fourthly, external push buttons & audible bell or buzzers are needed for conventional Annunciator. MBAS 9900 comes with built-in Push Buttons & built-in buzzer. Fifthly, where the user needs trip contacts, which is achieved by separate auxiliary relays & interlocked with other control circuits. MBAS 9900 comes with built-in 2CO trip contacts which are interlocked until all fault inputs normalize. Conventional relay & lamp design is always a clumsy design & tedious to trouble shoot. Most would prefer to avoid it as the cost of wiring up the components & labor is not worth it. The aesthetics cannot be better either. Best suitable for Control Panels & Switchboards of Diesel Powered Generators, AMF Controllers with trip interlocks, Engine driven Compressors, Fire Fighting pumps etc. Minilec MBAS 9900 can be used for following applications: The Diesel Generator Sets Panels Auto Mains Failure or Panels Diesel Engine Driven Screw Compressor Panel Diesel Engine Driven Crane Control Panel Gas based Captive Power Generator Panels
