Abstract—Fire Alarm Control Panel (FACP) components work together to detect fires, with IoT integration improving network connectivity. Standardization in IoT implementation in FACP systems is key to ensuring interoperability, security, and adequate data availability. Standardization is necessary to meet regulatory requirements and norms related to security. Until now, there are no international standards, as well as national standards in Indonesia, or specific technical recommendations for the selection and configuration of IoT systems in FACP systems. This research aims to recommend IoT standardization for FACP based on the results of technical tests for implementing the IoT system on FACP in terms of IoT Devices, IoT Networks, IoT Platform protocol, and IoT Applications. Based on the test results, it explores the connectivity options of IoT gateways, emphasizing their ability to interface with FACP via third-party interfaces with a validation rate of 100%, installing dual power sources, and increasing battery capacity. Cable networks are prioritized with backup internet connections, with Ethernet favored for its lower latency. The study suggests using HTTP or MQTT protocols for IoT platforms, aligning with established standards. For the IoT Application, comprehensive fire alarm status information, including location and detector status, is recommended. Usability testing validates these suggestions with high scores (Validation: 100%, SEQ: 5.4 – 6, SUS: 82, NPS: 100%), ensuring effective implementation of FACP IoT applications.
