The HONEYWELL HOME INTRUSION 4100SM is a serial interface module designed to extend communication capabilities within security control panel systems. It provides a serial data connection between compatible control panels and peripheral devices or subsystems, enabling structured data exchange across the installation. The 4100SM is typically installed by licensed security system technicians working on commercial or residential intrusion detection systems. Its role as an interface component makes it a critical link in panel-to-device communication architectures.
The 4100SM is suited for use as a control panel accessory in structured security installations where serial communication between the main panel and additional hardware is required. It is intended for professional installation in systems that demand reliable, low-latency data transfer between the control panel and connected modules or peripherals.
Designed as an OEM-style serial interface accessory for compatible security control panel systems. Consult system documentation to confirm compatibility before installation.
Installation should be performed by a licensed security or low-voltage technician in accordance with applicable local codes and the control panel manufacturer's wiring guidelines. Power down the control panel and disconnect backup battery before handling any panel accessory module. Follow all ESD precautions when handling the board. Verify serial port assignments and termination settings in the panel programming before bringing the system back online.
