iO64 Intelligent Life Safety System
The Edwards EST iO64 intelligent life safety system offers the power of high-end intelligent processing in a configuration that delivers an uncomplicated solution for small to mid-sized applications. With intelligent detection, electronic addressing, automatic device mapping, optional Ethernet® connectivity, and a full line of easily-configured option cards and modules, this flexible system offers advanced features that benefit building owners and contractors alike.
The iO64 provides one Class B analog device loop that supports up to 64 device addresses, and two Class B Notification Appliance Circuits (NACs). Optional Class A device wiring is available with the use of a module.
This life safety system features an attractive design that fits with any decor. Its distinctive doorfront offers a contemporary look that’s available with red or silver finishes. All LED indicators and its large backlit display remain easy to see at all times.
The iO64 supports a wide range of accessories and related equipment, including:
• Signature Series intelligent modules, detectors, and bases
• R-Series remote annunciators
• option cards that expand system capacity and extend system
capabilities.
