Selection Recommendations
Choose IS200KSPAH1BAA when both enhanced hardware reliability and specialized keypad/serial firmware are required. Verify “BAA” firmware matches your specific keypad and interface requirements before commissioning.
Precautions and Important Notes
Use ESD-safe handling. Verify field wiring and keypad/serial connections. Confirm “BAA” firmware supports your specific keypad and serial requirements. Never interrupt firmware updates. Board draws 2.0A – verify rack power capacity. Document all configurations. Store spares in anti-static packaging. Do not mix IS200KSPAH1BAA with other variants in redundant pairs without verifying identical firmware. Allow 30 seconds boot time. Test all keypad, serial, and highway functions during commissioning. The improved “B” hardware may require updated firmware in other system components. The IS200KSPAH1BAA is critical for local operator interface – ensure all settings are verified before placing in service. Ensure serial cabling does not exceed maximum recommended length. Regular verification of keypad and serial communication is recommended. If replacing another variant, verify all configurations are compatible with the new firmware before installation.
