IDNet 2 addressable device operation
Each addressable device on the IDNet 2 communication channel
is continuously interrogated for status condition such as: normal,
off-normal, alarm, supervisory, or trouble. Both Class B and
Class A operation is available. Sophisticated poll and response
communication techniques ensure supervision integrity and enables
T-tapping of the circuits for Class B operation. Devices with LEDs
pulse the LED to indicate receipt of a communications poll and can
be turned on steady from the panel. With addressable devices,
the location and status of the connected device is monitored,
logged, and displayed on the operator interface LCD. For precise
identification, each device has its own 40-character custom label.

The 4007ES Hybrid provides an IDNet 2 addressable initiating device
signaling line circuit (SLC) that supervises wiring connections and
the individual device communications status on the SLC. With 2
wire IDNet 2 SLCs, initiation, monitoring, and control devices such as
manual fire alarm stations, TrueAlarm sensors, control relays, and
sprinkler waterflow switches can communicate their identity and
status and receive fire alarm system control. Additional addressable
interface modules include circuit isolators, conventional IDC zone
adapters, and interface to other system circuits such as fans,
dampers, and elevator controls.
The CGM09090 and CGM04060 General Purpose
Application MS/TP Controllers (CGs) are equipment
controllers that run pre-engineered and user
programmable applications, and provide the inputs and
outputs required to monitor and control a wide variety of
HVAC and other facility equipment. CG series controllers
operate on an RS-485 BACnet® MS/TP Bus as BACnet
Advanced Application Controllers (B-AACs) and integrate
into Johnson Controls® and third-party BACnet systems.
CG series controllers include an integral real-time clock,
which enables the controllers to monitor and control
schedules, calendars, and trends, and operate for
extended periods as stand-alone controllers when offline
from the Facility Explorer® system network.
