Function diagnostics (only H85/DEC)
If there is an error alert (red L2 LED lit or intermittent), check the functioning of the keypads, as shown below:
• PROG key on the H85/DEC interface. The green L1 and red L2 LEDs go out.
• With each successive press of the PROG
•
If the green L1 LED blinks, the keyboard is functioning correctly.
If the red L2 LED blinks, it means that:
– the keypad does not work
– the keypad is not stored in the interface;
–
• Once the keypads have been checked, press the PROG key to return to normal operation; the green L1 LED blinks
rapidly.

Initial testing
• On power on, the L1, L2, A, B, C, D LEDs on the H85/DEC interface (L1, A, B on the H85/DEC2 interface) should
light up in sequence.
• Check the outputs OUT_A, OUT_B, OUT_C, OUT_D are enabled (if connected, only OUT_C and OUT_D for H85/
DEC2), by pressing the 1/A, 4/B, 7/C, */D function keys after unlocking operation by entering one of the user codes
in memory.
• Check that, with the memorised keypads, the green L1 LED blinks rapidly and the red L2 LED remains off (L2 only
for H85/DEC).
• Check the keypad's 6-LED back-lighting. When not in use, the LEDs are dimmed. They should become brighter after
pressing any key.

Maintenance
Perform scheduled maintenance every 6 months.
Check cleanliness and correct functioning.
If any dirt, moisture, insects or other foreign matter is present in the unit, disconnect from mains power and clean the
board and the housing.
Repeat the initial installation test procedure after cleaning.
If any corrosion is found on the printed circuit board, evaluate if it is necessary to replace the board itself.
24
User code entered incorrectly 5 times in a row. Keypad locks for 20 s.
If multiple keypads are connected to the interface card: one of the keypads is
transmitting a command.
POSSIBLE CAUSE
No fault.
Keypad communication error.
H85/DEC2 only: one of the two keypads is not functioning properly or is disconnected.
Repeated, but not serious, error in communicating with keypads. Check that cables
are not routed close to sources of interference.
System tamper alarm
Attempt to connect a keypad that is not recognized by the interface.
Link cable disconnected for more than 40 s (from at least one keypad).
The ALRM contact is open.
To reset the alarm, press the PROG key for 1 s, the L2 LED goes out and the ALRM
contact closes. Verify which keypad triggers the alarm as described in the paragraph
FUNCTION DIAGNOSTICS.
L1 or red L2 LEDs.
