Programming data

When you program data, you set numerical data or feature selection data.
Numerical data. Use the numeric keys of the system keypad with a number from 0 to 255. The system
uses a binary process, so to view the data, look at the LEDs for zones 1 through 8 and see which ones are
illuminated. When you add the illuminated LEDs together, you get the programming location. The numeric
equivalents of these LEDs include the following:
Zone 1 LED = 1
Zone 2 LED = 2
Zone 3 LED = 4
Zone 4 LED = 8
For example, if you want to program 66 in a location, press 6, 6 on the keypad. The LEDs for Zone 2 and
Zone 7 will illuminate, which indicates 66 is in that location (2 + 64 = 66). Once you program the data,
press the * key to enter the data and advance to the next segment for that location. After the last segment of
a location is programmed, you can press the * key to exit that location and turn the Ready LED off and the
Armed LED on. You can now enter another programming location. If you attempt to program a number
that is too large, the keypad sounder will emit a triple-beep and will await a valid entry.
Feature selection data. Feature selection data will display the current condition (on or off) related to the
eight features associated with the programming location and segment you selected. Press a button on the
touchpad (1 to 8) that corresponds to the feature number within a segment you require. That feature
number will illuminate (feature on). Press the number again, and the LED will extinguish (feature off). You
will see that you can select numerous features from within one segment. For instance, if you require all
eight segments, press 1, 2, 3, 4, 5, 6, 7, 8. LEDs 1 through 8 will illuminate as you press the keys, to
indicate that those features are enabled.

Using an LCD keypad

The steps to programming using an LCD keypad are identical to
difference is that the LCD keypad will prompt you for the data required. In programming mode, the number in
parentheses is the location you previously changed. For example, if the display reads Enter location,
then # (2), the system is telling you that Location 2 was the last location you programmed. In feature
selection data, the numbers of the enabled features are displayed. The features not enabled will include a
hyphen (-).
Zone 5 LED = 16
Zone 6 LED = 32
Zone 7 LED = 64
Zone 8 LED = 128
