Overview
EDWARDS brand intelligent life safety systems offer the power
of high-end intelligent processing in configurations that deliver
uncomplicated solutions for small to mid-sized applications. With
intelligent detection, electronic addressing, automatic device

mapping, optional Ethernet® connectivity, and a full line of easilyconfigured
option cards and modules, these flexible systems offer
versatility that benefits building owners and contractors alike.
The iO64 provides one Class B intelligent 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.
The iO1000 provides one Class A or Class B intelligent device
loop that supports up to 250 device addresses. Loop controller
modules may be added in combination to expand total system
capacity in 250-point increments to up to 1,000 device addresses.
The iO1000 panel includes four NACs that may be wired for either
Class A or Class B operation.
The RZI16-2 module adds even more capacity to iO installations
by adding up to 16 conventional device circuits and two additional
notification appliance circuits. This makes them an ideal retrofit

solution that can accommodate new intelligent detectors, as well
as existing conventional devices.
