Edwards 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 <br /> Compatible Electrical Box <br /> Cover Release Compatible Electrical Box <br /> Cover <br /> Release <br /> — <br /> Screw <br /> o <br /> 9 m� <br /> a <br /> Back Back ' <br /> Q Plate O Plate I <br /> 0 <br /> Toggle Toggle <br /> ° Switch ° Switch _ <br /> O'5, <br /> NOR,A <br /> Glass Rod d <br /> Glass Rod <br /> Release Lever <br /> OPEN <br /> 1111 / <br /> Figure 1.
