Section 6: Programming
duration of the double call timer (section [405]), the alarm system answers on the first ring.
OFF : Incoming calls are not answered using the double call routine unless the user enables the DLS window.
Note: This feature controls the DLS window for PSTN connections only.
2 – User Enables/Disables DLS
ON : The [*][6][Master Code][05] command enables a 6-hour window where, on power-up, downloading calls are answered
if a successful double call routine is detected.
OFF: The user cannot enable a downloading window.
3 – DLS CallBack
ON : When a downloading call is answered, both the computer and the alarm system hang up. The alarm system then calls
the downloading computer back using the downloading telephone number and begins the DLS session.
Note: Disable this option if using more than one downloading computer.
OFF : After successful validation, the downloading computer gains immediate access to the alarm system.
4 – User Call-Up
ON : A single call attempt can be made to the downloading computer using [*][6][Master Code][06].
OFF: [*][6][Master Code][06] does not allow initiation of a downloading session.
6 – Panel Call-Up and Baud Rate
ON : When a DLS/SA session is initiated by the user, the initial header is sent at 300 baud.
OFF: When a DLS/SA session is initiated by the user, the initial header is sent at 110 baud. The alarm system will then
switch to 300 baud in order to receive the response from the DLS computer.
7 – Alternate Communicator DLS
ON: When this feature is enabled, the alarm system responds to DLS requests through the alternate communicator IP or cel-
lular paths at any time, regardless of whether the DLS window is active or not.
However, if a pre-defined number of consecutive incorrect DLS access codes is detected (See "Remote Lockout DLS" on
page 95) while trying to establish a connection, alternate communicator DLS access is locked out until the next hour roll-
over.
OFF: When this feature is disabled, the alarm system only responds to DLS requests through the alternate communicator IP
or cellular paths when the DLS window is active.
The DLS/SA window is active following a power up or if enabled using [*][6][maser code][05] (System Service/DLS).
Note: This option controls DLS over alternate communicator only.
[402] PSTN DLS Phone Number Programming
This section is used to program the telephone number for DLS downloading over PSTN. This phone number is used for User
Call Up, Periodic DLS and DLS Call back. If no phone number is programmed, the system attempts to use the alternate com-
municator IP path (if configured).
The maximum number length is 32 digits.
[403] DLS Access Code
This 6-digit hexadecimal code allows the alarm system to confirm the identity of the downloading computer.
If the code does not match the computer, the alarm system does not allow DLS access.
Once a DLS connection is established, the operator is allowed three attempts to enter the correct access code. If these
attempts are unsuccessful, the alarm system disconnects and a new attempt must be made.
