The Edwards SIGI-IOI is a Signature Series input/output module with an integrated isolator (international version), for the Edwards EST4 life safety control platform (EN54) and other Edwards Signature analogue addressable systems.
It is an intelligent device offering three modes of operation: output with monitor input, input with programmable output, and input with direct output.
Key features
- Three modes: output with monitor input, input/programmable output, input/direct output
- Integrated line fault isolator
- Function set by an installer-selected personality code downloaded from the Signature loop controller
- All decisions are made at the module, giving very fast control panel response
- Signature Series intelligent device with on-board microprocessor (distributed intelligence)
- Self-diagnostics and history log stored in non-volatile memory
- Automatic device mapping by the Signature loop controller
- Fast, stable digital communication - shielded or twisted wiring is not required
Technical specifications
- Model: SIGI-IOI
- Type: input/output module with integrated isolator
- Data sheet reference: E85001-2004
- Signature loop controller: 3-SSDC2-E (single) or 3-SDDC2-E (dual) on the EST4 panel
