PROGRAMMING DATA TYPES
Programming data is always one of two types. One type of data is numerical and can take on values from 0 to 15 or 0 to 255 depending on
the location's segment. The other type of data is a feature selection type. Feature selection data is used to turn features on or off.
Examples are shown on page 10. Use the following procedures when working with these two data types.
NUMERICAL DATA
Numerical data is programmed by entering a number from 0-255 on the numeric keys of the system keypad. To view the data in a
location, a binary process is used. With this process, the LEDs for zones 1 through 8 are utilized, and the numeric equivalents of their
illuminated LEDs are added together to determine the data in a programming location. The numeric equivalents of these LEDs are as
follows:
Zone 1 LED =
1
Zone 2 LED =
2
Zone 3 LED =
4
Zone 4 LED =
8
Zone 5 LED =
16
Zone 6 LED =
32
Zone 7 LED =
64
Zone 8 LED =
128
Example: If the numerical data to be programmed in a location is "66", press [
6
]-[
6
] on the keypad. The LEDs for Zone 2 and Zone 7 will
become illuminated indicating 66 is in that location (2 + 64 = 66). See this example on page 10. Once the data is programmed, press [
r
] to
enter the data and advance to the next segment of that location. After the last segment of a location is programmed, press [
r
] to exit that
location, turn the "Ready" LED off and the "Armed" LED on. As before, you are now ready to enter another programming location. If an
attempt is made to program a number too large for a particular segment, the keypad sounder will emit a triple beep, indicating an error, and
remain in that segment awaiting a valid entry. On the LCD keypad, the number in the location will be displayed. For locations with a
maximum of 15, the hexadecimal equivalent will be displayed in parenthesis. Example:
11 (B)
or
14 (E)
.
FEATURE SELECTION DATA
Feature selection data will display the current condition (on or off) of eight features associated with the programming location and segment
selected. Pressing a button on the touchpad (1 thru 8) that corresponds to the "feature number" within a segment will toggle (on/off) that
feature. Pressing any numeric key between [
1
] and [
8
] for selection of a feature, will make the corresponding LED illuminate (feature ON).
Press the number again, and the LED will extinguish (feature OFF). You will see that numerous features can be selected from within one
segment. For instance, if all eight features of a segment are desired, pressing [
1
]-[
2
]-[
3
]-[
4
]-[
5
]-[
6
]-[
7
]-[
8
] will turn on LED's 1 thru 8 as you
press the keys, indicating that those features are enabled.
LCD Keypad Note:
The numbers of the enabled features will be displayed.
However, the features not enabled will display a hyphen (-). After the desired setting of features is selected for this segment, press [
r
].
This will enter the data and automatically advance to the next segment of the location. When you are in the last segment of a location and
press [
r
] to enter the data, you will exit that location. This will now turn the "Ready" LED off and the "Armed" LED on. As before, you are
now ready to enter another programming location.
