The Edwards SIGI-MM1I is a Signature Series single-circuit monitor module with an integrated isolator, for the Edwards EST4 life safety control platform (EN54) and other Edwards Signature analogue addressable systems.
It has a Class B normally open dry contact input, used to monitor devices such as fans, dampers and doors. When the input contact closes, an active signal is sent to the loop controller. The active condition is not latched at the module.
Key features
- One Class B normally open dry contact input
- Monitors fans, dampers, doors and similar equipment
- Non-latching active signal
- Integrated line fault isolator
- 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
