简介

该烟雾探测系统适用于建筑物火灾报警,符合 UL 268 标准第 8 版。 火灾报警器有两种类型:P 型和 R 型。 P 型要求低功耗,可将 100 多个探测器连接到一条线路上。 该系统将 MCU(RL78/G22)和光电烟雾探测器 AFE 相结合,组成了功耗极低、配置简单的火灾报警器。 此外,还可选配利用电力线通信(PLC)的高性能 R 型和智能火灾报警器。

系统优势:

  • 通过在 MCU 上应用 SNOOZE 模式定序器(SMS)进行操作,实现超低功耗。
  • 简化了 MCU 和光电烟雾探测器 AFE IC 的配置,最大限度地降低了对外部元件的需求,减小了 PCB 尺寸。
  • 降低功耗,增加传感器数量,从而减少建筑内的子系统数量。 这有助于降低部署成本。
