This smoke detection system for fire alarms in buildings is compliant with the UL 268 standard, 8th Edition. There are two types of fire alarms: P-type and R-type. The P-type requires low power consumption, allowing the connection of more than 100 detectors to a single line. This system combines an MCU (RL78/G22) and a photoelectric smoke detector AFE to create a fire alarm with ultra-low power consumption and a simple configuration. Optionally, high-performance R-type and intelligent-type fire alarms that utilize power line communication (PLC) are available.
