1: Security Features - Honeywell NOTIFIER SFP-5UD Series Manual

Transferring a Program
While the control panel is communicating with the remote Service Terminal, one of the DACT's red phone line active LEDs and the
green Kissoff LED will remain on steady.
In order to download the panel (whether initiated at the jobsite or remotely), the following must be true:
 The control panel must be in the Normal Mode of operation. Downloading is not possible if the panel is in any other mode
 There cannot be any active communications ongoing with a Central Station receiver
 All active events must be successfully 'kissed-off' by the Central Station(s). The communicator must be in a standby state with
no new information waiting to be transmitted to a Central Station
6.2.1 Security Features
Upload and download with the control panel have been carefully designed to include key security features to ensure proper functionality.
Any time a transfer is initiated, the control panel and the Service Terminal will communicate and transfer data before contacting a Cen-
tral Station. When the data transfers are completed and the control panel disconnects from the Service Terminal, the control panel will
call the Central Station and report one of the following conditions:
• Upload/download request received
• Upload and/or download request successful
• Upload/download failed
The key features are listed and explained in the following sections.
Secret Code Verification
A secret code is stored in the control panel by a Service Terminal to prevent unauthorized access. The secret code is created at the Ser-
vice Terminal by the master user and cannot be viewed or changed by anyone other than a master user. Viewing of the secret code is pro-
hibited at the control panel. Prior to allowing an upload or download of data, the control panel will verify the secret code transmitted by
the Service Terminal.
Time-out at Control Panel
Upon answering an incoming (modem) call on the primary Central Station phone line, the control panel will listen for a modem connec-
tion signal. If this signal is not received within 50 seconds, the control panel will disconnect the call. Upon successful connection (secret
code verified), if no communication occurs within 30 minutes, the panel will disconnect the call. Upon time-out, transfer activity will be
reported to the Central Station (if enabled) and the connection will be terminated.
Error Checking
As each block of data is received by the control panel, it is checked for accuracy. If an error is detected, the block is retransmitted until
correct, up to a maximum of four times. If the Secret Code is not verified and four errors occur, the call is disconnected and the report
that the upload/download was not successful is called to the Central Station(s).
Central Station Data Protection
The primary and secondary Central Station phone numbers, communications format, account code, test time and programmable event
codes are vital Central Station information. These blocks of data are protected from partial programming due to faulty phone connec-
tions, line noise and other errors. This prevents the panel from being confused due to a wrong phone number, account code, test time and
most critical formatting errors.
