Fire-Lite FCPS-24FS6(C/E Installation

This procedure outlines the mechanical installation steps required to install a PROM in the Power Supplies
listed in the title block.

Handling precautions for integrated circuits

Static electricity can destroy integrated circuits (ICs)! To prevent damage to the PROM, a wrist strap and a
static-free PLCC IC insertion/extraction tool is highly recommended. The manufacturer cannot be responsible
for damage to the PROM 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 on the fire 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 flattened
corner and dot on the body of the IC and the relationship to the flattened corner on the IC socket. The re-
placement PROM must be installed in the same manner as the PROM removed. Failure to observe this
orientation will result in destruction of the PROM.
