M INILEC offers its unique alarmAnnunciator based on the latest single

chip micro-controller technology with serialcommunication facility. Available in 19 rack type

enclosure. MBAS 9700 annunciators have split architecturefor 16, 24, 32, 40, 48, 64, 80 ,96 ,112 & 128 windows. 24, 32,

48, 64, 80, 96,112, & 12 8 window m odels are housed in 19 racktype enclosures, separate for MCU & for PSU. Here choice of facia

(DFU) is of 3 types (a) Sm all size i.e. 30 x 30 m m and (b ) Big size is 30x 65 m m ( c) 5 0 x 70 mm. (on request) Facia is available in multiples of16 windows. In addition to all other standard features, MBAS 9700has additional facility of computer linking. A serial port(RS232/RS485) o utput is available which c an be supported by an

IBM compatible PC of minimum 386 configuration. Minilec cansupply the standard software with every model or can

develop suitable softw are as per custom er requirementsor can provide source coding / protocol details to

enable client to develop their own suitablesoftware.

CONSTRUCTIONAL DETAILSMBAS 9700 consist of fourbasic sections1) The Power Supply Unit (PSUModule).2) The Main Control Unit (CPU +IOU Mo dule).3) The Display Facia Unit(DFU Mo dule).4) Computer interface.

THE MAIN CONTROLUNIT (MCU)CPU module is the MainProcessing Unit of MBAS9700 which scans andprocesses the incoming faults i g n a l s f r o m t h e v a r i o u spotential free field contactsthrough IOU module, and drivesthe corresponding LED window s

and the audible device in order toannunciate the fault through IOUmodule. The IOU module is theinput & output interfacing unit.To each IOU mo dule 16 inputcontacts (potential free) & 16w i n d o w L E D ' s c a n b econnected.

THE DISPLAY FACIAUNIT (DFU)

T h e F a c i a b l o c k i saccessible from front (in

capsules. The sandwichedphoto film window inscriptionsare press fitted on the windowcapsules.

For 16 to 12 8 points system theDFUs are g iven sep arately.

OPTIONAL FEATURES Different colored LED's in eachwindow for easy differentiationof c ritical faults. Customized preprogramm ed

COMPUTER INTERFACE

The MCU unit transmits fault information to computer serially.

RS232/RS485 standard is used for ser ial communicat ion.

Communication protocol modbus ASCII / RTU can be offered. In

computer user-friendly software is written. This software offers on-

line Date & Time setting, Legend setting, Display window & also it

gives fault repor t with o n demand p rinting facility.
