Firmware Change
This procedure outlines the mechanical installation steps required to install EPROMs in the MS-9200, MS-9200C
and MS-9200E.
Handling precautions for integrated circuits
Static electricity can destroy integrated circuits (ICs)! To prevent damage to the EPROM, a wrist strap and a
static-free IC insertion/extraction tool is highly recommended. The manufacturer cannot be responsible for
damage to the EPROM as a result of improper handling.
System Power Sources
Always remove primary and secondary power before working on the system!
1. Disconnect battery backup power before working on the system!
2. Proceed by disconnecting AC power to the panel at the main service circuit
breaker (not the circuit breaker at the alarm control panel's power supply).
3. Wait 60 seconds to allow for capacitive discharge before touching any of the
system's components.
4. Reverse the procedure for powering up the system - AC first - then batteries.
Integrated Circuit Pin Conversion
Observe proper orientation of any IC removed or installed! Note location of Pin 1 with respect to the notch in the
body of the IC. The replacement EPROM must be installed in the same manner as the EPROM removed. Failure
to observe this orientation will result in destruction of the EPROM. NOTE: Some ICs may have a small dot instead
of a notch for orientation purposes.

EPROM Replacement
Observe proper orientation of any IC removed or installed! To replace the EPROM, complete the following steps:
1. Make certain Software Revision and Circuit Board Revision are compatible (refer to table on page 4).
2. Once all power has been removed, disconnect any optional modules (if installed).
3. Locate EPROM U16 on newer boards or U14 on older boards (center right of the board).
4. Gently loosen and remove EPROM from the board.
5. Install replacement EPROM. Observe proper orientation! The notch or dot on the IC
should be positioned to the left for U16 in the newer boards or to the right for U14 in older boards as
shown below. Use care to insure that the EPROM's pins are not bent or broken during insertion.
6. Reconnect power supplies.
