If the code entered is the same as the previous one, then
the procedure has been successful and the green LED LV
lights up for 2", the buzzer will remain on until the LED
turns off.

Advanced features: masking the code

CAUTION! This feature is automatically enabled when
using 6-digit user codes.
To increase the level of security of the installation, a
masking function provides you the ability to "hide" the
actual code in the middle of randomly keyed digits, of any
desired quantity. The code that will be considered will be
composed of the last 6 digits entered before the asterisk
key *.
If you press the asterisk key * you will not receive any
signal from the LEDs or buzzer.
We use <previous random digits> and <following random
digits> to indicate the random number sequences typed
by the user before the <6 digit user code>, and after having
pressed the asterisk key *, respectively; the typing sequence
with masking code will therefore be the following:
<previous random digits>
<6 digit user code> *
<following random digits> *
If the <6 digit user code> is present in the memory then
the green LED LV lights up, at this point you can press a
function button (provided it is matched to the stored user
code) to activate the interface relay.
For example, to activate the 6-digit code 245672 you can
type the following sequence:
294862...308236 245672 * 057986...791964 *
and finally the function keys A, B, C, D output contact.
NOTE: The numbers are irrelevant and not necessary.
Activation can be done by simply typing 245672 * *.

Keyboard error message

Any time the typed sequence is not correct the error signal
will be given, by emitting 5 quick flashes of the red LED LR,
accompanied by the intermittent activation of the buzzer.
An error signal can occur for the following reasons:
• The entered number is not recognized (for example, you
typed an incorrect password or a user code that is not
present in the memory).
• You are trying to enter a code or password with more
than 6 digits (only in programming) or less than 3 digits
(in all modes).
• In the deleting of a user code mode or during the
password change mode if there is a difference in the
first number inserted and the confirmation number.
• If you are trying to store a code already present in the
memory
• If a begun sequence has not been completed; for
example, if you enter a code, but you do not press the *
character after a few seconds the keypad will signal an
error message
• When running a storage or cancellation operation and
the # key is typed instead of the asterisk *.

Keypad lock message

If you enter an incorrect user code 5 consecutive times,
the keyboard will start to flash the red and green LEDs (LR
and LV) in an alternating manner and then shuts down for
20 seconds. Pressing any key within those 20 seconds will
only show the lockout signal again.

Interface messages

The H85/DEC interface includes a green LED L1 and red
LED L2 which give out signals communicating normal
operation, or of anomalies that occur while communicating
with the keyboards.
• L1
flashes quickly:
communication with keyboards
• L1 is flashing slowly: non-repetitive errors in
communicating with the keyboards
• L2 off: no alarm detected
• L2 turns on for 3 seconds: reveals a repetitive non-critical
error in communication with keyboards. Check that the
cables connecting the keyboards do not pass through
interference sources (e.g. power switching devices)
• L2 turned on: system tamper alarm; an attempt to
connect a keyboard that is not recognized by the interface
was detected, or there was a disconnection of the
communication cable (from at least one keyboard) for
more than 40 seconds. The ALRM contact terminal is open.
To reset the alarm, press the PROG key for 1 second, the
LED L2 turns off and the ALARM contact closes.
To check which of the keyboards caused the alarm
(temporary or permanent), proceed as detailed in
paragraph 9.1 COMMUNICATION FAILURE DIAGNOSTICS.
9.1

Communications failure diagnostics

If you see that the red LED L2 flashes from time to time, or
lights up steadily (alarm), then it is possible to check which
keyboard caused the problem.
Proceed as follows:
• briefly press the PROG key: the green LED L1 and the red
LED L2 will switch off;
• every time you press the PROG key a verification of
the keyboards 1 through 4 is made; the number of the
keyboard in question is indicated by the number of
consecutive flashes of the green LED L1 or the red LED L2:
if the green LED flashes, this means that for that keyboard
number everything is functioning properly, if the red LED
flashes than this means that there is an error for that
keyboard (E.g. keyboard 3, three flashes of the green LED
that recur after a brief pause indicates that the keyboard
3 is communicating correctly with the interface).
• After verifying the 4 positions, another press of the
PROG key returns you to normal operation: the green
LED will blink quickly again
