The keys described above will be referred to in this manual by the names shown in the left-hand
column on the previous page. The cursor is normally a flashing /\ symbol. In normal operation,
when the cursor is pointing up, the number or phrase in the centre of a key is chosen when that
key is pressed. If the SHIFT/DELETE key (generally referred to as the SHIFT key) is pressed
once, the cursor changes to a < symbol and the upper, left-hand letter or character of each key is
available. For example, in the case of the NO key, this is a "B" and, in the case of the RETURN
key, it is a space, designated by the space bar symbol. This cursor mode is called LEFT SHIFT.
Pressing the SHIFT key a second time will change the cursor to a > symbol and the upper,
right-hand letter or character is then available. This is a ":" in the case of the NO key and "%" in
the case of the RETURN key. This cursor mode is called RIGHT SHIFT. Pressing the SHIFT
key again will return the cursor to a /\ symbol and each key will have its original meaning. In
text- entry mode, when the cursor is pointing up, the bottom character on non-numeric keys (e.g.,
+) becomes available instead of the operating phrase (e.g., FULL DISARM). If you examine the
layout of the keys, you will see that the letters used most often are available in left shift. This is
convenient for zone-description entry as most descriptions can be completed without having to
shift between characters. Because the keyboard has non-tactile keys, an audible feedback (a short
beep from the piezo-sounder) confirms each operation of a key.
All keys have an auto-repeat capability. If a key is pressed for longer than one second, the panel
will generate about four duplicate characters a second until the key is released. The SHIFT key
operates differently. If pressed for longer than one second, it will delete characters at about half
the normal repeat rate. This is used when editing to delete errors made during zone-description
entries, name entries, etc. To correct an error, ensure that the flashing cursor is pointing up.
Press the BACKSPACE (²) key to position the cursor over the error. Press and hold the SHIFT
key to delete the incorrect character or characters, reposition the cursor and enter the correct
character or characters (these will appear on the display, automatically moving the rest of the
entry to the right), and use the YES key (in normal shift) to move the cursor right (forward
space) to continue.
To summarize the editing functions:
- BACKSPACE: Cursor in normal shift; press BACK SPace key.
- DELETE: Press and hold SHIFT/DELETE key.
- FORWARD SPACE: Cursor in normal shift; press YES key.
- SPACEMAN: Cursor in left shift; press RETURN key.
The keyboard, made from high-grade polycarbonate, is very durable and can easily be cleaned
with a damp cloth. Although firmly attached with contact adhesive, the keyboard can be peeled
off if it is damaged without having to replace the cabinet.
