CLOCK ADJUST
Clock Adjust
Number of seconds to adjust (speed up/slow down) the clock each day must be be-
tween 0-55 seconds.
Note: Repeated use of these Functions are not "cumulative" (this means, for example,
if the clock has already been set to speed up 10 seconds per day, and then is found to
need an additional 10 seconds, then program 20 seconds using Function 43).
Example 1: Clock is losing 13 seconds every day, enter:
; 4 3 ; 1 3 :.
This example assumes that the Clock Adjust setting was at the factory default of zero.
Function 57 can be used to print the current Clock Adjust setting.
Example 2: Clock is gaining 13 seconds every day, enter:
; 4 4 ; 1 3 :.
This example assumes that the Clock Adjust setting was at the factory default of zero.
Function 57 can be used to print the current Clock Adjust setting.
Example 3: To set the clock adjust setting back to the factory default of zero, enter
; 4 3 : or ; 4 4 :
43. Speed Up Clock
(This Function enabled through keypad only)
44. Slow Down Clock
(This Function enabled through keypad only)
PASSAGE MODE
Passage Mode Enable/Disable - Schedule will Override
•
Function 45 allows passage through the door without the need for a User Code. Re-Lock using Function 46.
•
Programmed Schedules will override the state of the lock when Functions 45 and 46 are used. If it is required that pro-
grammed schedules do not override Passage Mode, enable/disable Passage Mode using Functions 48/49. Note: Because
of the temporary nature of these features, Functions 45-47 can only be enabled using the keypad.
45. Enable Passage Mode
(This Function enabled through keypad only)
46. Disable Passage Mode
(This Function enabled through keypad only)
47. Timed Passage Mode
(This Function enabled through keypad only)
•
Hours must be between 1 - 999.
Function 47 allows passage through the door without the need for a User Code for the programmed amount of time.
•
For example, if you wish your office door lock to be unlocked (unlocked = "Passage Mode") for the next 3 hours,
enter Program Mode and press: ; 47 ; 003 :
Programming Functions (cont'd)
Clock Accuracy
The internal oscillator is factory calibrated to an accu-
racy of ±5 minutes/year. Changes in ambient tem-
perature may affect accuracy. If necessary, the ac-
curacy of the internal clock may be adjusted by first up-
dating the correct time via Function 39. After an interval
of about 1 month, re-set the correct time via Function 39
and then print an Audit Log via Function 55. Because
the Audit Log displays both the "New Clock Time" and
the "Old Clock Time", a daily accuracy (in seconds) can
be determined by taking the difference in seconds be-
tween the "Old" and "New" times divided by the number
of days between the two Function 39 entries. Note:
Because the minimum available adjustment is 1 second
per day, the inaccuracy of the clock must exceed about 6
:
minutes per year before adjustment is necessary.
