particular device is required. Some devices do not have more than
one sub-point, which means that their only valid sub-point number is 0.
For example, point 241.25.2 refers to the Battery Connection point
which registers the status of the battery connection. The parts of this
point number are as follows:
241 is the equipment number of the controller in the MX1,
25 is the Power Supply device number,
2 is the sub-point for the Battery Connection.
This is displayed and entered as 2 4 1 . 2 5 . 2
Point numbers for devices on the MX addressable loops can be readily
constructed if you know their addresses. Entering a point number of 1.A
will show the state of sub-point 0, by default, of device A on the first in-
built loop.
The inbuilt MX loop on the controller board is equipment number 1 and
the optional loops start at equipment number 2.
Use NEXTF3 to step through any other sub-points of the device, for
example, the photo and heat parts of a multi-sensor detector.
For MX loop devices, sub-point 0 represents the physical device, and is
responsible for logging to the history and printer the Device Fail and Type
Mismatch events. Note that when these events occur, all points for the
device will enter the fault state, but only sub-point 0 will log these events.
Disabling sub-point 0 will prevent the logging and signalling of fault by
only sub-point 0, but will not prevent the fault being indicated on the other
points.
For accessing a point on another MX1 panel in a networked system, the
SID of the other panel is multiplied by 1000 and added to the equipment
number. For example, to access point 1.23.0 on an MX1 panel with a
SID of 12 you would use a point number of 12001.23.0.
When disabling an MX device that is in Device Fail or Type
Mismatch, it will be necessary to disable all sub-points of the
device to remove the fault indication.
To access a point on another MX4428 panel in a networked system, the
SID of the other panel is multiplied by 1000 and added to the responder
number. Because MX4428 doesn’t have sub-points, the sub-point
number is left off. For example, to access point 64.5 on MX4428 SID 13
you enter 13064.5.
The device is represented by a number Eq.Dev and is used to perform
operator actions on all sub-points of that device, without performing
commands individually or requiring an operator to successfully enter the
point range. For example, entering a point number 1.1 at the Disable
