M 1/10/08 ECN 08-019 P/N 50053:M 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. Pin 1 Notch 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.
