Edwards SIGI-CC2I Dual Input Signal Module w/ Isolator

The Edwards SIGI-CC2I is a Signature Series dual input signal module with an integrated isolator, for the Edwards EST4 life safety control platform (EN54) and other Edwards Signature analogue addressable systems.

On command from the loop controller, a signal module connects supervised Class B signal or telephone circuits to their power inputs. The power inputs can be polarised 24 Vdc to operate audible and visual signal appliances, or 25 and 70 Vrms to operate audio evacuation speakers and firefighters' telephones. Three personalities are available.

Key features

• Two power inputs for supervised Class B signal or telephone circuits
• Drives 24 Vdc sounders and beacons, or 25/70 Vrms speakers and firefighters' telephones
• 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
