    • A power saving wireless fire alarm system has a master station and a plurality of battery-powered fire detecting terminals linked for wireless communication with each other. Upon detection of a fire occurrence at one of the fire detecting terminals, the fire detecting terminal transmit a fire detection message to a master station which in turn transmit a wake-up message to the other fire detecting terminals and thereafter a fire information message which starts a multiple synchronous communication between the master station and the fire detecting terminals. Each fire detecting terminal has a power controller which selects an intermittent reception mode of activating its own receiver only intermittently until receiving the wake-up message or information indicative of the fire occurrence, and select a constant operation mode thereafter to make the fire detecting terminals be ready for the multiple synchronous communication commenced by the fire information message from the master station.
    • 省电无线火灾报警系统具有主站和多个电池供电的火灾检测终端,用于彼此无线通信链接。 在火灾检测终端中的一个检测到火灾发生时,火情检测终端向主站发送火灾检测消息,主站又向其他火情检测终端发送唤醒消息,之后发送起火信息消息 主站和火灾检测终端之间的多重同步通信。 每个火灾检测终端具有功率控制器,其选择间歇地激活其自己的接收机的间歇接收模式,直到接收到唤醒消息或指示火灾发生的信息,并且此后选择恒定操作模式以使火情检测终端为 准备好从主站的火灾信息消息开始的多个同步通信。

    • An air intake passage system includes an external air intake port provided in a rear portion of a top cover and a passageway section projecting upwardly from the engine cover for directing taken-in external air to the engine. The top cover is provided over the engine cover with a gap therebetween such that the taken-in external air is allowed to flow into the passageway section and a water discharge section is provided between the engine cover and the top cover. Water, having entered together with external air, flows along the upper surface of the engine cover, bypasses the passageway section and is then discharged via the water discharge section.
    • 进气通道系统包括设置在顶盖的后部的外部空气进气口和从发动机盖向上突出的用于将引入外部空气引导到发动机的通道部分。 顶盖设置在发动机罩上方,其间具有间隙,使得吸入的外部空气被允许流入通道部分,并且在发动机罩和顶盖之间设置有排水部。 与外部空气一起输入的水沿着发动机盖的上表面流动,绕过通道部分,然后经由排水部排出。
