Typical Wiring <br /> The detector mounting bases accept#18 AWG(0.75mm2),#16 Audible Sounder Bases, Fire Mode <br /> (1.Omm2), 414 AWG(1.5mm2), and#12 AWG(2.5mm2)wire sizes. AB4GT1 A134G,A134G-LF sounder bases <br /> Sizes#16 AWG(1.Omm2)and#18 AWG(0.75mm2)are preferred <br /> for ease of installation. <br /> Standard Detector Base,SIGA-SB,SIGA-SB4 SIGA-AB4GT, o O SIGA-AB4G-LF: <br /> SIGA-AB4G, ®Jumper cut® Output Mode <br /> This is the basic mounting SIGA-AB4G-LF: Default=Fire <br /> base for EDWARDS Signature I(-)) <br /> Volume Setting Cut/remove jumper <br /> g Default=High for Fire plus CO <br /> Series detectors.The SIGA- resistance Cut/remove <br /> er wire jumper for SIGA-AB4G: <br /> LED Remote LED is supportednot exceed low dB ® ® Tone Setting <br /> bbh 0 Ohms Default=Temporal <br /> y this Base.
