Specifications

D2: D2 displays on the Backup Type menu if Host/Net is selected under Communication Type.

Select D2 to supervise a second telephone line using an optional Model 893 or 893A Dual Phone

Line Module.

RS-232: On XR500 Series version 118 or higher, RS-232 displays on Backup Type menu if Network

is selected under Communication Type.

Messages are sent using RS-232 after they have failed to communicate with the programmed

Primary NET IP and Backup IP. Select RS-232 when using DB-9 backup communications by directly

connecting to the RS-232 port on the panel. Set the panel J23 jumper to R and briefly reset the

panel using the J16 jumper to activate RS-232 operation. Refer to the XR500 Series Installation

Guide.

When Net Backup is YES and a Modem String is programmed, an Automatic Recall Test is sent

using the RS-232 line based on the normal programming selections in Test Frequency, Net Fail

Time, Defer Test Time, and Test Time options just as they do for DD. When the RS-232

Automatic Recall Test fails to communicate, a Warning: Panel Backup Communications Fail (S12)

report is sent using the Primary NET IP. The next time the panel successfully sends a report over

the 2ND LINE, a Backup Communication Line Restore (S04) report is sent.

None: When you select None, the panel does not send signals on the second (backup)

communication line.

Digital Dialer (DD): Select Digital Dialer when you are using DMP SDLC format for communication

over standard telephone lines to an SCS-1, SCS-1R or SCS-105 receiver.

Main Account Number: This is the account number that the panel uses to report all system troubles,

fire alarms, supervisory alarms, and automatic recall tests.

For the iCOMsl enter an account number between 1 and 65535. In input mode, the account number

entered here is reported to the receiver.

In keypad mode, the account number reported to the receiver originates from the panel attached to

the iCOMsl. The account number entered here, when in keypad mode, is used for programming with

Remote Link only. The iCOMsl and the panel have separate account numbers.

Transmission Delay: Enter the length of time that you want the panel to wait before sending burglary

reports to the central station. Select a time from 1 to 60 seconds. Alarm bells and relay outputs are

not delayed during this period. Enter 0 (zero) to disable transmission delay.
