True Hybrid Fire Detection – Seamless Integration of Wired and Wireless Devices
The control panels support up to:· 1–4 addressable loops· 250 devices per loop, and· 250 wireless devices via up to 8 expandersThis hybrid infrastructure makes the system ideal for new installations, system upgrades, and retrofit projects where mixed wiring conditions exist. -
Comprehensive Communication Interfaces for Modern Fire Networks
The series offers rich connectivity options, including:· non-polarized two-wire bus for wired addressable devices communication· 868MHz for wireless devices communication· RS232, CAN/RS485 for multi-panel linking· LAN, 4G for cloud or remote monitoringThese interfaces allow easy integration with BMS, cloud platforms, and third-party fire monitoring systems. -
Long-range Communication — 2000 m Wired / 1500 m Wireless
Each wired loop supports a communication distance of up to 2000 meters, and the wireless network supports a communication range of up to 1500 meters.These distances meet the requirements of large or distributed building layouts and help ensure reliable signal transmission in both wired and wireless configurations. -
High-extensibility Alarm & Control Outputs for System Integration
The panels include multiple alarm outputs and programmable relay interfaces:· HM-921: 4 sounder circuits + 4 relays + 24V auxiliary power outputThis ensures compatibility with sounders, strobes, HVAC shutdown, door control, and evacuation systems, supporting comprehensive fire protection deployment. -
Optimized User Interface and Fast Response Performance
· <10 seconds system response time· 4 security access levels· numeric keypad + quick-access keys· Clear 3.5-inch LCD displayThese features improve operational efficiency for installers, firefighters, and facility managers, delivering a smooth and intuitive user experience.
