The Edwards SIGA-CC1SI is a Signature Series synchronisation output module for Edwards EST4 (EN54) analogue addressable systems. It connects a supervised output circuit to a 24 Vdc riser on command from the Signature loop controller, operating polarised audible and visual appliances that have an adjustable resynchronising feature. The output wiring is monitored for open and short circuits, and a short circuit causes the panel to inhibit activation so the riser is not connected to the wiring fault.
Key features
- Connects a supervised output circuit to a 24 Vdc riser
- Drives polarised audible/visual appliances with resynchronisation
- Output wiring monitored for open and short circuits
- Short circuit inhibits activation to protect the riser
- 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
- Riser input: 24 Vdc
- Output: 1 supervised audible/visual signal circuit
- Data sheet reference: E85001-0704
- Signature loop controller: 3-SSDC2-E (single) or 3-SDDC2-E (dual) on the EST4 panel
