Recommendations for Reducing False Alarms

Program Option CL Program Function Comments

Arming/Combination 09 (2) Combination This feature is enabled to prevent unauthorized users from

Options Command 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).

Arming/Combination 09 (4) Chirp Alert This option minimizes the possibility of creating an error when

Options 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.

Loop Control 1F - 26 (2) Loop Response This option determines the response time of the loop itself. It acts

Time as a buffer on the loop to minimize the possibility of fast acting

sensors, such as swingers on window foil, producing false alarms.

Loop Control 1F - 26 (3) Loop Restore This option is used in conjunction with CL 17 - 1E Digit Positions

Type (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.

Loop Control 1F - 26 (4) Loop Arming There may be occassion where it is desirable to program all doors

Type 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.

Event Reporting 2A (5 & 6) Cancel Report This feature should always be enabled on reporting systems,

Code/Cancel especially if the system does not send Opening and Closing

ReportReceiver Reports. A Cancel Report is sent to the monitoring station in the

Select 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.
