The Edwards SIGI-CT2I is a Signature Series dual-input Class B input module with an integrated isolator, for Edwards EST4 (EN54) analogue addressable systems. It connects Class B normally open alarm, supervisory or monitor dry contact initiating circuits to the Signature data loop, with the module's function set by one of four installer-selected personality codes.
Key features
- 2 Class B input circuits for normally open dry contacts
- Alarm, supervisory or monitor operation
- Four personality codes available
- 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
