Control Panels The MGD 32 Main Annunciator is a 32 Circuit Annunciator which may be expanded with up to four AGD 048 Adder Chassis to a maximum of 224 Circuit Display Points The MGD 32 has no button LEDs on the board Each Circuit Output will drive off board Indicators such as LEDs or on a GRAPHIC DISPLAY to form a graphic annunciator The drivers may be mounted using the metal plate included in the package to any of the approved backboxes or within graphic display It is intended that the MGD 32 and the AGD 048 are combined with a DISPLAY to make a graphic annunciator These graphic drivers have individual supervision circuitry which helps to identify burned out lamps Features Enclosure Models Steel enclosure finish painted semi gloss off white Material BB 5008 16 GA 0.060 thick CRS GA

needs to be Shielded Pair shown in the The wire may be AWG up to ft AWG up to ft RS 485 wiring the Fire Alarm Panel to the must point to point from FA Panel to the Annunciator then next Annunciator so on No star or T tapping allowed FROM FIRE ALARM OR PREVIOUS TWISTED SHIELDED PAIR TO NEXT ANNUNCIATOR SHIELDED PAIR VDC POWER FROM FIRE ALARM CONTROL PANEL PREVIOUS ANNUNCIATOR ONE PAIR VDC POWER TO NEXT ONE PAIR All circuits are power limited and use type FPL FPLR or FPLP power cable 4 RS 485 and 24V DC Power Wiring DC Power Wiring MGD 32 Annunciator Driver module has a 120 ohm End of Line Resistor on its RS 485 terminals This is removed on all except the last wired Module 24 V DC field wiring needs to be of an appropriate gauge for the number of annunciators the total wiring run length Refer to section 7.0 on page 21 to calculate the maximum for all annunciators summed together then use chart below to calculate size of wire for length of wire run Instruction Loop 1 Annunciator 24V DC Power Wiring Table Maximum Current all Annunciators Accidentally connecting any of the 24 VDC wires to the RS 485 wiring will in damage to the annunciator and or to the fire alarm control panel to it is connected Switch Settings Cabling Master Graphic Driver MGD 32 needs to be assigned a unique sequential Address via Main Chassis DIP Switch SW1 The AGD 048 does not require addressing Annunciator address refer to the manual for the specific fire alarm control panel being is set according to the table below 2 MGD 32 Annunciator Addresses Switch A0 A1 A2 A3 Address when used with FX 2000 version 2 X X or higher FX 350 MR 2350 MR 3500 FleX Net MMX and SFC 500 16 bit checksum when used with FX 2000 FA 1000 FA 300 MR 2300 FR 320 FA 200 and SFC 200 8 bit checksum Annunciators on a common RS 485 connection must be numbered sequentially 1 2 3 4 and not randomly such as 5 3 2 1 all Annunciator addresses are valid for all fire alarm control panels Address all switches off is not allowed and will generate an annunciator remote trouble Refer to the Fire Alarm Control Panel Manual for further information Switch Settings Cabling BOARD Cabling for the AGD 048 Annunciator Connects to the MGD 32 Main Chassis or to the AGD 048 Adder Chassis The AGD 048 its power from the Master Driver Connects to the next AGD 048 Annunciator Chassis Terminals L1 to L48 are zones Cabling for the
