The recommendations contained in this section are designed to assist you in reducing false alarms. The first column
contains the Command Locations and Digit Positions in parentheses ( ). The second column is the recommended program
option followed by a brief explanation.

This feature is enabled to prevent unauthorized users from
activating certain keypad functions. When activated, this
command will require a valid User Combination to perform such
functions as Bypassing a Zone, Group Bypassing, Keypad
Activated RPS, Central Station and Bell Testing, and Instant
Arming. For additional assistance with commands requiring User
Combinations, see page 21 (Command Summary).
This option minimizes the possibility of creating an error when
exiting. The system is armed in the normal manner and the user
exits through the delayed exit door. If the door does not close
properly (returning the loop to the normal state), the system will
transition from the Exit Delay to the Entrance Delay upon the
completion of the Exit Delay time the Bell will chirp , alerting the user
to the error in arming the system.
This option determines the response time of the loop itself. It acts
as a buffer on the loop to minimize the possibility of fast acting
sensors, such as swingers on window foil, producing false alarms.
This option is used in conjunction with CL 17 - 1E Digit Positions
(3 & 4), Restore Reporting Code, and CL 2A (2), Restore Receiver
Select. The panel can be programmed to send a Restoral Report
only when the loop is normal and the system is disarmed. With this
arrangement, any loop which is triggered multiple times while
armed will only send one alarm report until the system is disarmed.
This prevents the system from tieing up the central station receivers
and the phone line with continuous alarm and restoral reports.
There may be occassion where it is desirable to program all doors
and interior points as delayed. Or you may need to program
interior zones to be delayed only during the Entry/Exit Delay
Time. This Command Location allows a variety of Arming Types
to help minimize false alarms.
This feature should always be enabled on reporting systems,
especially if the system does not send Opening and Closing
event that an Authorized User clears the alarm while the bell is
still active. The Cancel Report Code (Digit Position 5) is actually
a two-digit code with the first digit being programmed by the
installer and the second digit being the User ID # when the report
is sent. Digit Position (6) determines which receiver gets the
Cancel Report.
