BOSCH FPD-7024 ROM Installation

As discussed in a previous post, we showed you how to confirm your current ROM version on the Bosch FPD-7024 fire alarm control panel.  Now we will tell you how to install the ROM version 1.01 if necessary.

Important!

• Before removing the D7039 Mux Expander Module and replaceing the ROM, remove all AC and battery power to the Bosch FPD-7024.
• Failure to follow the instructions in this procedure can damage the FACP.
• The D7039 and FPD-7024 have static sensitive components and must be handled with care.  Follow the anti-static procedures when handling these modules.

Steps:

1. Disconnect the power sources to the Bosch FPD-7024
2. Carefully remove the D7039 Mux Expander Module by disconnecting it from the FPD-7024 and lifting it off of the standoffs.  It is not necessary to disconnect any of the wiring to the D7039 including the ground.

3. The ROM is located under the D7039 Mux Expander Module to the left of the display.  See picture.
4. Use a flat-head screwdriver.  Place the end of the screwdriver in the slot at the end of the chip.  (I actually perfer to use a chip puller tool)
5. Gently pry the chip from the board by lifting it straight up.
6. Discard the old ROM chip.
7. Place the new ROM version 1.01 over the socket.  Ensure that the notched end of the ROM aligns with the notched end of the socket.
8. Slowly push straight down on the ROM until all pins are correctly seated.  The pins on both sides of the ROM should enter the socket at the same time.
9. Reinstall the D7039 by aligning the mounting holes with the standoofs and press the module to seat it securely into the connector on the Bosch FPD-7024.
10. Reconnect the AC and battery power to the Bosch FPD-7024.
