Versions Software Versions proceeding with the EPROM installation check to confirm that the software EPROM installed in MS 9200 C E is compatible with the LCD 40 software If software with either the Part Number 73750 or 73829 is installed in the MS 9200 C the Series Annunciator must have software with a Part Number of 73779 or 73879 to with the FACP Fire Alarm Control Panel If software with a Part Number of or higher is installed in the MS 9200 C the LCD 40 Series Annunciator must software with a Part Number of LCD40V20 or higher to operate with the FACP If software with a Part Number 73846 is installed in the MS 9200E the LCD 40 Series Annun must have software with Part Number 73779 or 73879 to operate with the FACP If with Part Number M9200EV20 or higher is installed in the MS 9200E the LCD 40 Annunciator must have software with a Part Number of LCD40V20 or higher to with the FACP Handling precautions for integrated circuits Handling precautions for integrated circuits Handling precautions for integrated circuits Handling precautions for integrated circuits Handling precautions for integrated circuits electricity can destroy integrated circuits ICs To prevent damage to the EPROM a wrist strap and static free IC insertion extraction tool is highly recommended The manufacturer cannot be responsible damage to the EPROM as a result of improper handling EPROM Access and LCD 40 Removal EPROM Access and LCD 40 Removal EPROM Access and LCD 40 Removal EPROM Access and LCD 40 Removal EPROM Access and LCD 40 Removal Remove the upper and lower retaining screws from the trim ring and remove the trim ring Remove the mounting screws along the outer edge of the LCD 40 flange Pull the LCD 40 out of the 3 gang electrical box to gain access to the connectors in the System Power Sources System Power Sources System Power Sources System Power Sources System Power Sources remove primary and secondary power before working on the system to disconnecting power from the LCD 40 be sure to note the orientation of the seven power connector P2 and the four terminal EIA 485 connector P1 on the rear of the These plug in type terminal connectors are utilized for ease of serviceability When SURE SURE these plug in connectors BE SURE SURE to align the rounded groove on both the plug SURE connector and mating connector on the LCD 40 Printed Circuit Board Enough force can be placed on these connectors to make them fit in the reverse direction 1 1 1 1 Disconnect power from the LCD 40 by removing the seven terminal power connector P2 the back of the LCD 40 This should ONLYONLYONLYONLYONLY be done while power is still removed from MS 9200 C E For ease of serviceability the four position EIA 485 terminal connector should also be removed Reverse the procedure noting proper orientation for powering up the LCD 40 and reinstall the EIA 485 connector 1 Circuit Pin Conversion Circuit Pin Conversion Circuit Pin Conversion Circuit Pin Conversion Circuit Pin Conversion proper orientation of any IC removed or installed Note of Pin 1 with respect to the notch in the body of the IC The EPROM must be installed in the same manner as the removed Failure to observe this orientation will result in of the EPROM NOTE Some ICs may have a small dot of a notch for orientation purposes of 4 of 4 of 4 of 4 of 4 50373 Rev D 12 9 98 P N 50373 D EPROM Replacement EPROM Replacement EPROM Replacement EPROM Replacement EPROM Replacement ensure that power is disconnected and the LCD 40 is removed from the wall mounting Observe proper of any IC removed or installed To replace the EPROM complete the following steps Unscrew the three retaining screws holding the printed circuit board to the metal flange Be careful to twist the membrane switch ribbon cable while the printed circuit board and flange are separated Disconnect the two wire key switch connector from header P6 Locate the EPROM on the printed circuit board For EPROM location refer to illustration below Gently loosen and remove the EPROM Install the replacement EPROM Observe proper orientation The notch or dot on the IC should be toward the center of the board as illustrated below Use care to insure that the EPROM s pins not bent or broken during installation Reconnect the printed circuit board to the flange using the screws from Step 1 Make sure that both membrane switch connector and the two wire key switch connector P6 are both properly Reconnect the power P2 and EIA 485 P1 connections to the rear of the LCD 40 printed circuit After reconnecting the power and EIA 485 connections apply power to the MS 9200 C E and ensure the LCD 40 display matches the MS 9200 C E LCD display If no problems are encountered remount the LCD 40 with the screws from Step 2 of Section III Access and
