The IDNet options allow the use of addressable devices and TrueAlarm sensors with the
4100U-S1 FIP. Addressable devices communicate the exact location of an alarm to the system
operator interface panel, improving recognition of the condition and subsequent response. It
also pinpoints the precise location of fault conditions via the device custom label. Throughout
this section, operations described for IDNet are also applicable for Mapnet.
When a IDNet device changes to an abnormal condition, or the operator enters a IDNet
device address, the LCD display shows the current status of the IDNet device. After entering a
IDNet device address, press the <MORE INFO> key on the operator interface panel to display
additional device information.
Each IDNet device must have a point address in order to communicate with the 4100U-S1
FIP. These point addresses along with their custom labels are located in the Programmers
Report. The Programmers Report shows the address for each device, separated by hyphens.
Hyphens must be used when entering a IDNet address into the system. An example of a
IDNet device address is "M1-5". The "M1" portion of the address identifies the IDNet loop or
channel , loop 1 or channel 1. The "5" portion of the address, identifies the device number,
number 5.
Note:
New multipoint IDNet devices use
sub-point addressing
. These sub-points are
addressed as C-DD-S, where S is the sub-point. Example: A FRIAM device has a
relay at sub-point 1 & an input at sub-point 2 which would be accessed as M1-5-1 &
M1-5-2.
See Chapter 5, "Selecting Points for Status or Control" for IDNet operations.
If an IDNet device will not reset, you may decide to disable the point with the <DISABLE>
key. When the disable procedure is performed, a System Fault occurs to remind you that the
point is disabled. The disable procedure is the same for all system points (see section 2, "How
to Disable a Point"). Maintenance personnel must be called immediately to repair the
malfunction.
After the IDNet point is repaired, you can enable the point again.
Using the 4100U-S1 LCD and the display/action keys, the control panel can display various
status conditions for each TrueAlarm sensor, the sensor's present selected sensitivity level as a
percent of obscuration per foot. This selected sensitivity level is the value at which the FIP
will cause an alarm condition. Seven (7) sensitivity levels are available for the TrueAlarm
photo-electric sensor. The most sensitive setting is 0.2% OBS/FT (0.5% OBS/M) with the
least sensitive setting being 3.7% OBS/FT (12% OBS/M).
Other individual sensor status conditions that can be displayed on the LCD display are shown
below. These displays are accessed by either entering an IDNet device number for a normal
device using <IDNET> key, or by pressing the <FAULT ACK> key for an abnormal device.
To display each of the categories the <MORE INFO> key and the <NEXT> and
<PREVIOUS> keys are used as shown below.
