IDNet Addressable Device Control
Overview. The 4010ES with ESS provides dual IDNet
(IDNet 2) addressable initiating device Signaling Line
Circuits (SLCs) that supervise 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.
IDNet 2 Addressable Device Operation
Each addressable point on the IDNet 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 allow for "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 with
each device having its own 40 character custom label for
precise identification.
TrueAlarm Addressable Sensor Operation
Addressable initiating device communications
include operation of TrueAlarm smoke and temperature
sensors. Smoke sensors transmit an output value based on
their smoke chamber condition and the CPU maintains a
current value, peak value, and an average value for each
sensor. Status is determined by comparing the current sensor
value to its average value. Tracking this average value as a
continuously shifting reference point filters out
environmental factors that cause shifts in sensitivity.
TrueAlarm Addressable Sensor Reference
TrueAlarm Photo
Sensor with Base
Programmable sensitivity of each sensor can be
selected at the control panel for different levels of smoke
obscuration (shown directly in percent) or for specific
heat detection levels. To evaluate whether the sensitivity
should be revised, the peak value is stored in memory and
can be easily read (or downloaded as a report) and
compared to the alarm threshold directly in percent.
CO sensor bases combine an electrolytic CO sensing
module with a TrueAlarm analog sensor to provide a
single multiple sensing assembly using one system
address. The CO sensor can be enabled/disabled, and can
be used in LED/Switch modes and custom control. (refer
to data sheet S4098-0052 for details)
TrueAlarm Photo/Heat
Sensor in CO Base
TrueAlarm heat sensors can be selected for fixed
temperature detection, with or without rate-of-rise detection.
Utility temperature sensing is also available, typically to
provide freeze warnings or alert to HVAC system problems.
Readings can selected as either Fahrenheit or Celsius.
TrueSense Early Fire Detection. Multi-sensor
4098-9754 provides photoelectric and heat sensor data using
a single 4010ES IDNet address. The panel evaluates smoke
activity, heat activity, and their combination, to provide
TrueSense early detection. For more details on this
operation, refer to data sheet S4098-0024.
Diagnostics and Default Device Type
Sensor Status. TrueAlarm operation allows the control
panel to automatically indicate when a sensor is almost dirty,
dirty, and excessively dirty. The NFPA 72 requirement for a
test of the sensitivity range of the sensors is fulfilled by the
ability of TrueAlarm operation to maintain the sensitivity
level of each sensor. CO Sensors track their 10 year active
life status providing indicators to assist with service
planning. Indicators occur at: 1 year, 6 months, and end of
life.
Modular TrueAlarm sensors use the same base and
different sensor types (smoke or heat sensor) and can be
easily interchanged to meet specific location requirements.
This allows intentional sensor substitution during building
construction when conditions are temporarily dusty. Instead
of covering smoke sensors (causing them to be disabled),
heat sensors may be installed without reprogramming the
control panel. The control panel will indicate an incorrect
sensor type, but the heat sensor will operate at a default
sensitivity to provide heat detection for building protection
at that location.
IDNet Device Wiring Reference
IDNet Addressable Channel Capacity. The ESS
provides dual electrically isolated IDNet 2 signaling line
circuits (SLCs) that support up to 250 addressable monitor
and control points intermixed on the same pair of wires.
IDNet 2 SLCs are isolated from other system reference
voltages to reduce common mode noise interaction with
adjacent system wiring.
