The Edwards SIGA-RB Relay Detector Base is a Signature Series intelligent mounting base with an integrated relay. It accepts any Signature Series detector head and provides a Form C dry-contact relay output for auxiliary control. Therefore, the SIGA-RB combines detector mounting and a programmable supervised relay in a single ceiling-mounted assembly.
Edwards SIGA-RB relay operation
The dry contact is rated for 1 amp pilot duty at 30 VDC. Furthermore, Normally Open or Normally Closed operation is selected during installation. The relay position is supervised to detect accidental disturbance out of position. In addition, the SIGA-RB can be operated as a control relay if programmed at the control panel.
Wiring terminals
Terminal 1: Normally-Open. Terminal 2: DATA IN/OUT (+). Terminal 3: Common. Terminal 4: DATA IN (-). Terminal 5: Not used. Terminal 6: Normally-Closed. Terminal 7: DATA OUT (-). However, the SIGA-RB relay base does NOT support the SIGA-LED Remote LED. For remote LED indication, use the SIGA-SB or SIGA-SB4 Standard Detector Base instead.
Compatible electrical boxes
North American 1-gang box. 3-1/2 in by 1-1/2 in (38 mm) deep octagon box. 4 in by 1-1/2 in (38 mm) deep octagon box. European 1-gang (75 mm) box with 60.3 mm fixing centers. BESA box. In addition, max wall-mount distance from ceiling is 12 in (305 mm).
Wiring
The base accepts 12, 14, 16, or 18 AWG wire (2.05, 1.5, 1.0, 0.75 sq mm). Sizes 16 and 18 are preferred. Furthermore, break the wire run at each terminal — do NOT loop signaling-circuit field wires around terminals. Write the assigned detector address on the supplied label and apply it to the inside rim of the base.
