The Edwards EST SIGA-SDPCB is the factory replacement printed circuit board (PCB) for the SIGA-SD SuperDuct duct smoke detector. When an SIGA-SD unit fails at the board level, the SIGA-SDPCB allows technicians to restore full detector functionality by replacing only the PCB rather than the complete detector assembly, reducing both parts cost and installation labor.
As a genuine Edwards OEM replacement part, the SIGA-SDPCB ensures full compatibility with the Signature Series SLC loop protocol and maintains the original device address, sensitivity calibration, and diagnostic reporting capabilities of the SIGA-SD housing. This makes it the correct choice for maintaining SIGA-SD detectors in EST3, iO64, and iO500 installations.
