Typical Wiring <br />The detector mounting bases accept #18 AWG (0.75mm'), #16 <br />(1.0mm2), #14 AWG (1.5mm'), and #12 AWG (2.5mm2) wire sizes. <br />Sizes #16 AWG (1.Omm2) and #18 AWG (0.75NNm2) are preferred <br />for ease of installation. <br />Standard Detector Base, SIGA-SB, SIGA-SB4 <br />This is the basic mounting base <br />for EDWARDS Signature Series <br />detectors. The SIGA-LED Re- <br />mote LED is supported by this <br />Base. <br />Tern Doe'dEdon <br />1 Not Used <br />2 DATA Ed on <br />3 Not Used <br />4 DATA IN (-) <br />4 Remote LED (-) <br />6 Remote LED (+) <br />6 NotUsed <br />7 DATA OUT O <br />Remote LED <br />per wire <br />_ must not exceetl <br />to Ohms <br />)ATA IN n 0 0 0 DATA OUT (-1 <br />DATA IN hir DATA OUT LA <br />From Signature Con[rdler To Next Device <br />or Previous Device <br />Isolator Detector Base, SIGA-IB, SIGA-1134 <br />This base includes a built-in line fault isolator for use on Class A <br />circuits. A detector must be installed for it to operate. The isolator <br />base does not support the SIGA-LED Remote LED. <br />The isolator operates as follows: <br />- a short on the line causes all iso- <br />lators o ° o O <br />to open within 23 msec e <br />- at 10 msec intervals, <br />beginning on one side °� <br />of the Class A DATAIN(- �z DATAOUTO <br />circuit nearest the loop <br />controller, the isolators <br />close to provide the DATA IN DATA car a) <br />next isolator down the From Slgnalure Controller To Next DenI <br />or Prel Device <br />line with power Term D:IN/OUT <br />1 No <br />- when the isolator next 2 DAto the short doses, it reopens within 10 3 DA4 Nomsec. 6 No6 DAThe process repeats beginning on the T No <br />other side of the loop controller. <br />Relay Detector Base, SIGA-RB, SIGA-RB4 <br />This base includes a relay. Nor- <br />mally Open or Normally Closed <br />operation is selected during in- <br />stallation. The dry contact is rated <br />for 1 amp (pilot duty) @ 30 Vdc. <br />The relay's position is supervised <br />to avoid accidentally jarring it out <br />of position. The SIGA-RB can be D^T' <br />operated as a control relay if pro- <br />grammed to do so at the control DATAIj <br />panel. The relay base does not F aec°r�i�a.;D` i.
