Section 13: Downloading

NOTE: DLS-3 v1.3 or higher is required. Downloading is not to be enabled on UL Listed systems.

13.1 Downloading Options

Automatic Upload of Event Buffer when %75
full
Ref #: [000300]
This option allows the installer to choose if the panel will
automatically call the downloading computer when the
Event Buffer %75 full event occurs. This option is indepen-
dent of the actual transmission of the Event Buffer %75
full event (the event does not need to be transmitted for
the panel to perform the automatic upload). The panel
will first transmit the Event Buffer %75 full event (if
enabled) and then perform the automatic download.
Downloading Telephone Number
Ref #: [000302]
Enter the telephone number for the downloading com-
puter (only applies if the User Call Up, Periodic DLS, or
DLS Callback option is enabled). For instructions on pro-
gramming telephone numbers, see 12.1 'Telephone Num-
bers'.
Panel ID Code
Ref #: [000303]
The 4-digit panel identifier code will identify the panel to
the downloading computer. The panel ID code must be
different for each panel if either User Call Up, Periodic
DLS or DLS Callback is used. The default setting is 4921.
Panel Downloading Access Code
Ref #: [000304]
This 4-digit code must be programmed the same as the
downloading access code in the computer file. If the codes
are different, the panel will NOT allow any uploading or
downloading to take place. The code is used to help ensure
the security of the system. The default setting is 4920.
Double Call Timer
Ref #: [000305]
This is the maximum time between two telephone calls
when the 'Double Call' option has been enabled. Valid
entries are between 000 and 255 seconds. The default set-
ting is 060 (see 'Downloading Toggle Options – Double
Call' below to enable the Double Call feature).
Number of Rings
Ref #: [000306]
This is the number of consecutive rings the panel must
detect before answering the call for downloading. Valid
entries are between 001 and 255 rings. The default setting
is 008.
Downloading Toggle Options
Ref #: [000300]
Downloading to the panel is not enabled by default. Select
one or more of the following options to allow the com-
puter to communicate with the control panel. Use the [*]
key to toggle between [Y]es and [N]o to enable or disable
each option. Use the [<][>] keys to scroll through the avail-
able options.
• DLS Enabled: If enabled, the panel will answer an
incoming call for downloading after the programmed
number of rings. The panel can also be programmed to
answer using the double call feature (see 'Double Call'
in this section). If disabled, the panel will not answer
any incoming calls (default=No).
• User Call Up: If enabled, the user can make the panel
call a remote computer by entering the [*][6][Master
Code][12] User Call Up command (default=No).
• Double Call: If enabled, the panel will follow the dou-
ble call procedure. If the panel detects one or two rings
on the first call and then is called again within a pro-
grammed time, the panel will answer the second call
on the first ring. To program the Double Call Timer, see
'Downloading Options – Double Call Timer' above. If
disabled, the panel will only answer after the pro-
grammed number of rings (default=No).
• DLS Callback: If enabled, both the computer and the
panel will hang up after a connection is made. The
computer will then wait for the panel to call. If dis-
abled, the downloading computer will have immedi-
ate access to the control panel once accepted as valid
(default=No).
NOTE: If more than one computer is used for down-
loading, callback should be disabled.
• Periodic DLS: This feature can be used to have the
panel periodically call the downloading computer.
Upload/download
advance (batch files) will be executed. See 13.2 'Peri-
odic Call-up' for programming the time and days
when this will occur. The computer must be waiting
for a call in order for this feature to work (default=No).
• User Enabs DLS: If enabled, the user will be able to
activate the ring detect feature for 60 minutes in order
to allow downloading to occur. If the DLS Enabled
option is on, this option will not apply (default=No).

13.2 Periodic Call-up

Ref #: [000301]
This option programs the time and number of days
between periodic downloads:
• Periodic TX Days (00): Program the number of days
between periodic downloads. Valid entries are from 001
to 255 days. The default setting is 030.
• Periodic TX Time (01): Program, in military time, the
time of day the panel will call the computer for periodic
downloading. The default setting is 00:00 (midnight).

13.3 PC-Link

Ref #: [000307]
The PC-Link is an adapter that connects the control panel
to a computer to provide on-site downloading. With the
PC-Link, no modem is required. The time that is required
to complete a successful download is significantly
reduced. A serial cable is used to link the computer with
the control panel.
For instructions on using the PC-Link, please consult your
DLS-3 Software Manual ('Connecting Via PC-Link').
