Kidde recommends that these fire alarm <br /> stations be installed according to latest recognized edition of national and local fire alarm codes. <br /> Electronic Addressing: The loop controller electronically addresses each manual station, saving valuable time during system com- <br /> missioning. Setting complicated switches or dials is not required. Each station has its own unique serial number stored in its on-board <br /> memory.The loop controller identifies each device on the loop and assigns a"soft"address to each serial number. If desired,the stations <br /> can be addressed using the SIGA-PRO Signature Program/Service Tool. <br /> Key-Latch Compatible Electrical Box <br /> Compatible Electrical Box Cover Release <br /> Cover <br /> v - y Release <br /> Screw <br /> ° Back ff0� aBack <br /> O Plate o O Pate <br /> 0 <br /> Toggle Toggle <br /> ° Switch Switch <br /> O QRMAL O NORMa o` <br /> 0 <br /> Glass Rod O <br /> a® Glass Rod <br /> Release Lever <br /> OPEN <br /> O <br /> Figure 1.
