SYSTEM REAL-TIME-CLOCK (Location 55)
This 24 hour real-time-clock provides the daily time base for starting and stopping the function of
inhibition to relay output 1 (mainly for electric door lock strike).
No real-time-clock setting is required if daily start-stop inhibition at Location 56 is not
enabled.
(1) LOCATION
Key in Location
(2) CURRENT REAL TIME
– The current time in Hour and Minute. The allowed time figure is 00:00 – 23:59
The time setting is based on 24 hours daily with the first two digits for hours and
the last two digits for minutes. The time in second always starts at 0 0.
(3) VALIDATION
Press key once.
Two-beep confirms the setting and the clock starts to count in 24 hour basis from the programmed
current time.
Programming Examples:
a) Set the current time of “10:30” (AM) to the keypad ----
b) Set the current time of “6:45” (PM) to the keypad ------
IMPORTANT NOTE:
1) The real-time-clock stops after power failure, which makes the real-time inhibition loses
its time base. It is necessary to re-program the system’s real-time-clock unless the
keypad is back up with UPS.
2) The keypad gives warning beeps of 3 fast beeps / 5 seconds continuously after
power failure until the real-time-clock is re-programmed.
3) No “after power failure warning beep” will be given if Location 56 is not programmed
with Start/Stop times.
4) Suggest to program the clock every 3-6 months to keep time accuracy; or when time
deviation is found.
