Exception Reports
•
This option allows the reporting of openings and closings to the central station only if the
arming and disarming occurs outside of the predetermined opening and closing time
windows.
•
This option is set in partition-specific field 2*09.
•
The system can be programmed to send No Opening and No Closing reports if the
partition is not armed or disarmed by the end of the corresponding time window.
Time-Driven Events
•
By using the time windows, the system can automatically activate and de-activate relays
at predetermined times to turn lights or other devices on and off.
•
The time-driven events can be activated at different times in relation to the time window:
1. At the beginning of a time window
2. At the end of a time window
3. During a time window active period only (on at beginning of window, off at end)

The system can perform the same actions on a daily basis, or can be made to perform an
action only once (i.e., turn on the porch light this Wednesday at 8:00 pm).
•
The system also provides up to 20 programmable "timers" available to the end user for
the purpose of activating output devices at preset times and on preset days.
Limitation of Access of Users by Time
•
A user's access can be limited to a certain time period, during which he can perform
system functions. Outside this time, that user's code will be inactive.
•
The system provides up to 8 access schedules, each consisting of two time windows
(typically one for opening, one for closing) for each day of the week and two time windows
for holidays.
•
The access schedules are programmed in the #80 Menu Mode, and enabled for a given
user when that user's access code is added to the system.
•
If a user tries to operate the system outside of the schedule, the alpha keypad will display
"Access Denied."

Time Window Definitions

which an event may take place.
•
A time window is defined by a "Start" time and a "Stop" time.
•
The system supports up to 20 time windows.
•
The windows are shared by all 8 partitions, and are used when programming the various
schedules (open/close, limitation of access), as well as for time-driven event control.
