6. PROGRAMMING
The SABL has ten numbered keys and an “E” key which is used for several functions. Each of
these keys is read separately by the unit, so the SABL is a true 11 digit access device. This
provides excellent security against a code being guessed. Also, the SABL employs non-volatile
EEPROM memory so that all programming is retained in a power failure and during battery
replacement.
Another point to note is that all SABL codes will operate the unit when their sequence is entered
regardless if other incorrect digits were entered before. For instance, if the correct code is 2-2-
6-7, the unit will operate if 8-2-2-6-7 is entered. An exception to this is if a total of 16 wrong
digits are entered. In that case, an alarm function comes into play. The keypad will lock itself
out for 15 seconds and the beeper will sound continuously. This feature discourages attempts to
guess the code.
Before learning all programming options for the SABL, you should decide how you want the
unit to be used. Then learn only the appropriate programming for that use. This simplifies the
task of operating the unit and cuts down on unneeded service calls.
The programming questions to ask are: do you want a “fixed” code that will either never be
changed or changed only rarely? Or do you want regular code changes from the keypad?
This issue depends on the amount of security called for in the application. Finally, do you want
multiple codes? The SABL supports 55. The purpose of multiple codes is to assign different
codes to individuals or groups. Then if a code needs to be changed, the other individuals or
groups need not go to the trouble of learning a new code. This is a convenience issue.
6.1. Fixed Programming
Employ fixed programming in a situation where the end user is not likely to ever change the
code, or at least that changes would be rare. Fixed programming can be used in lower
security "traffic control" applications, as the longer the code remains unchanged, the greater
the risk that an unauthorized person will be able to learn it.
The SABL makes it simple for you to program the unit in this “fixed” way. You will utilize a
push button set, single code called the “Hard Code”. With power applied to the unit, note
that the yellow LED is on and will remain on for 5 seconds (after the last pressed
key). This signals that all code memories are empty. This is important as you don’t want
any unknown codes present in the unit. If the yellow LED does not illuminate after a key is
pressed, see Section 6.5 for the procedure to clear any (and all) existing codes.
Once you have confirmed the yellow light indication on the keypad, remove the battery cover
and press the button on the CPU board marked “HARD” for about one second. Returning to
the keypad, you will see the yellow LED flashing slowly (about once per second). This
indicates “hard programming mode”. Within 30 seconds, simply enter your code from two
to seven digits (you can’t use the “E” key but repeating digits are OK). If you wait longer
than 30 seconds to start your code entry, the “programming window” will terminate and you
will have to press the “HARD” button again. In general, longer codes provide more security
but are less convenient to remember and enter. However, many users prefer seven digit
codes as they can be phone numbers, which are easy to remember. Do not pause while you
are entering the code as any time there is more than a five second gap between keys
being pressed, the unit will stop reading the sequence. Note that a successful button
press is echoed by a beep and a flash of the green LED. When you have completed entering
your code, hit the “E” key and you should see the red LED display two pulses within a
second. If you don’t hit the “E” key, your code will be accepted anyway but it will take five
seconds to see the two red flashes. If you have selected a seven digit code, the two red
flashes will occur immediately as the digit limit has been reached. The two pulses signal that
your code has been accepted. If you get a single one second long red pulse, your code
has not been accepted. Pressing one key and waiting for over 5 seconds, for example, would
be interpreted as a disallowed single digit code.
If you get the single red flash, press the Hard Code button again and you can attempt to re-
enter a successful code. Once you get the two red flashes, re-enter your code and the door
should open. “Fixed” programming is complete. Should you ever want to change the code,
