20. 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.

Key in Location 55
(2) CURRENT REAL TIME
HH : MM – The current time in Hour and Minute. The allowed time gure is 00:00 – 23:59
The time setting is based on 24 hours daily with the rst 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 conrms 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 ---- 55 1030 #
b) Set the current time of “6:45” (PM) to the keypad ------ 55 1845 #
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.
The keypad gives warning beeps of 3 fast beeps / 5 seconds continuously after power failure until the
real-time-clock is re-programmed.
No “after power failure warning beep” will be given if Location 56 is not programmed with Start/Stop
times.
Suggest to program the clock every 3-6 months to keep time accuracy; or when time deviation is found.
