Edwards EST SIGA-SDPCB Replacement PCB and Sensor Kit

The Edwards EST SIGA-SDPCB replacement PCB and Signature sensor kit restores the intelligent addressable electronics of existing duct detectors in the SIGA-SD SuperDuct housing, without changing the installed box, sampling tubes, or conduit. It includes a factory-assembled circuit board, sensor package, and replacement rubber seals so you can refresh both the electronics and critical air-sealing components in one service visit. Key Specifications: Type: Replacement PCB and Signature sensor kit for SIGA-SD duct smoke detector Core Function(s): Replaces the original SIGA-SD electronics and sensing head to restore intelligent photoelectric duct smoke detection and auxiliary relay control Loop/Protocol: Signature SLC via the host SIGA-SD duct detector Power: 15.2 to 19.95 VDC from SLC, same operating current ratings as the original SIGA-SD detector Indicators/UI: Uses the existing SIGA-SD housing LEDs and magnet test switch once installed Compatible Devices & Accessories: SIGA-SD – SuperDuct intelligent duct smoke detector housing and base System Compatibility: Restores Edwards Signature loop compatibility for existing SIGA-SD duct detectors on Signature Series fire alarm control panels.
