Section 22. REMOTE PROGRAMMING

AND CONTROL (DOWNLOADING)

General Information

The AM100 can be remotely programmed from an IBM compatible Personal

Computer (PC), a HAYES modem, and Ademco's V-LINK® Software (as

specified below).

Downloading may only be performed if a technician is at the site.

Programming the control from a remote location is protected against

compromise by someone attempting to defeat the system, using multi-levels

of security protection:

1. Security Code Handshake: An 8-digit download ID code must be matched

between the control and the downloader .

2. Site Initiated Remote Programming: The installer or subscriber initiates

the callback from the subscriber premises (by entering Installer code + # + 1)

while disarmed. All parameters can then be downloaded via the phone lines

using a personal computer.

3. Station Initiated Remote Programming: The operator calls the site from

your office to initiate the download call. The control hangs up and then calls

back the PC via the preprogrammed telephone number. The unit can then be

uploaded, downloaded, or controlled from your office .

4. Telco Hand-off: Allows the installer or subscriber to perform a download

session on the call initiated from the site.

5. Data Encryption: Data passed between the PC and the control is

encrypted for security so that it is very difficult for a foreign device tapped

into the phone line to take over communication and substitute system

compromising information.

Equipment Required

• AM100 and keypad.

At the installer's office/home:
