CAUTION System Reacceptance Testing after Software Changes - To insure proper system operation, this product must be tested in accordance with NFPA-72 requirements. The requirements for "Changes to all control units connected or controlled by the system executive software" include a 10-percent functional test of the system, which includes a test of at least one device on each input and output circuit to verify critical system functions such as notification appliances, control functions, and off-premises reporting. NOTI·FIRE·NETTM is a trademark of Notifier, 1994. www.PDF-Zoo.com firealarmresources.com K1 Document 15744 1/09/2004 Rev: P/N 15744:K2 ECN: 03-767 Installation Guidelines Handling Precautions for Integrated Circuits Static electricity can destroy Integrated Circuits (ICs)! To prevent damage to the ROMs being changed in this procedure, a wrist strap and a static-free IC insertion/ extraction tool is highly recommended. Notifier cannot be responsible for damage to ROMs or other integrated circuitry in the system as a result of improper handling techniques. Always keep ROMs on a static-free mat or surface. Static Control Wrist Strap 3M Series 2200 Charge Guard or equivalent Static-Free IC Insertion/Extraction Tool (select size & type suitable for use with the IC(s) which require extraction) Static-Free PLCC Extraction Tool (select size & type suitable for use with the PLCCs which require extraction) Static-Dissipative Work Surface 3M Series 8300 Charge Guard (or equivalent) connected to Earth Ground System Power Sources Always remove primary and secondary power before working on the system! 1) Disconnect battery backup power first by removing the Battery Interconnect Cable. 2) Proceed by disconnecting AC power to the panel at the main service circuit breaker (not the circuit breaker at the fire 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. WARNING! Failure to follow this procedure can result in a loss of program memory. Pin 1 Integrated Circuit Pin Convention Notch Pin 1 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 ROM must be installed in the same manner as the ROM removed. Failure to observe this orientation will result in destruction of the ROM. DIP PLCC www.P2DF-Zoo.com firealarmresources.com Field Change Procedure 15744:K1 1/09/2004 AM2020/AFP1010 ROM Replacement Compatibility Warning To ensure complete compatibility between AM2020, AFP1010 boards and NOTI·FIRE·NETTM system boards, all ROMs in the system(s) must be changed at the same time. The control panel will not function properly with a mix of ROMs from different software levels. In addition, all ROMs from the same software level are not necessarily compatible. They must comprise a valid software combination. Consult the factory to determine whether or not your particular software part numbers will function as a group. The affected ROMs are listed in the table below.

For example, AROM6-CPU is a CPU-2020 ROM containing Revision Level 6 software. ROM Installation 1) Disconnect secondary (DC) power. 2) Disconnect primary (AC) power. CAUTION! Remove AC power at the main service circuit breaker (not the circuit on the Main Power Supply) or all the programming information may be lost! 3) Replace each ROM as outlined in the respective sections. 4) Connect primary (AC) power. 5) Connect secondary (DC) power. 6) After all replacement ROMs have been installed, the entire system must be completely tested. Note: With the exception of new features, replacing the ROMs does not usually require re-entry of the system application program. 7) Please place all ROMs removed from the system into the static-protected boxes (provided with the replacement ROMs) and return them to the following address: ATTN: Software Engineering, Notifier, 12 Clintonville Road, Northford, Connecticut 06472-1653. www.PDF-Zoo.com Field Change Procedure 15744:K1 1/09/2004 3 firealarmresources.com AROM(n)-CPU / NROM (n) for CPU-2020 · Open the Display Interface Assembly (DIA) door. · Using an IC insertion/extraction tool, carefully remove ROM U2 from the CPU-2020 and place it on an antistatic surface. · Observe proper orientation and ensure that none of the pins are bent.
