NOTIFIER AFP-200 ROM Field Software Change Procedure
Field Software Change Procedure
Document #15632 Rev. B 5/20/93 ECN 93-119 P/N 15632:B
Firmware Change
This procedure outlines the mechanical installation steps required to install EPROMs in the AFP-200.
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!
- Disconnect battery backup power before working on the system!
- 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).
- Wait 60 seconds to allow for capacitive discharge before touching any of the system’s components.
- 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 # | Release # | Summary of Changes |
|---|---|---|
| 73354 | 1.0 | Initial Release |
| 73397 | 1.1 | Increases 4-wire smoke detector reset time and changes the |
operation of releasing zones 93-94
73441| 1.2| Changed AFP-200 operation to: 1) limit maximum alarm verification
time setting to 30 seconds (CSFM requirements) and 2) delay “loss of AC” for
DACTs (new UL/NFPA requirements). Add: 1) global acknowledge for ACS
annunciators, 2) trouble tone for terminal mode LCD-80s and 3) style D
operation for MMX-1 and MMX-2 modules. Software refinements were made in Auto
programming, Up load/down-load, detector sensitive programming, obscuration
display, detector testing, default setting,
EPROM Replacement
Observe proper orientation of any IC removed or installed! To replace the
EPROM, complete the following steps:
- Once all power has been removed, disconnect any optional modules (if installed).
- Locate U9 (bottom right of the board).
- Gently loosen and remove U9 from board.
- Install replacement EPROM in location U9. Observe proper orientation! The notch or dot should be on the right-hand side of the IC. Use care to insure that the EPROM’s pins are not bent or broken during insertion.
- Reconnect power supplies.
Programming and Testing
Reprogram and test the AFP-200 after EPROM replacement.
