AlTstFail (Alarm Test Fail)
–
the component has previously
undergone an alarm test and has failed. This state clears after a
successful alarm test.
As well as having a state, some points can also have values. For a
smoke detector, one point could have a value to represent the smoke
level. For a heat detector, one of its points could have a value to
represent the current temperature. For an internal system point for
battery status, one value might represent the battery voltage.
MX1
uses points to represent most of its internal and external
components. The system configuration controls the way these points
interact to provide the required system operation. Point information can
be accessed from the
MX1
front panel.
Used when networking
MX1
panels. The SID is a unique number in the
range 1-254 (address) allocated to each panel or device on the network.
A point number has the form
Eq.Dev.Sub
which consists of three parts:
Eq
is the equipment number, which indicates which equipment part of
the system is involved.
Dev
is the physical device number within the particular equipment
part, which will usually relate to a specific part of the system such as a
detector or power supply.
Sub
is the sub-point number, which indicates which part of the
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

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
NEXT

to step through any other sub-points of the device, for
example, the photo and heat parts of a multi-sensor detector.
