System Overview
Introduction
Congratulations on your purchase of Honeywell's 7845i-GSM combination Internet/GSM
communication module. It represents the latest and most innovative communication
technology for the security industry and uses the most sophisticated encryption to ensure the
highest level of security for your customer.
Not only will alarms and other messages be transmitted via this module, the 7845i-GSM
provides uploading/downloading capability of Honeywell's control panel data (when
connected), over the Internet or via the AlarmNet-G network, using GSM (Global System for
Mobile) technology when the internet is not available.
The 7845i-GSM module requires an AlarmNet–I account. For new installations, please obtain the
account information from the central station prior to programming this module. For replacement
installations, the AlarmNet-I account is created automatically when the module is registered (based on
the existing 7845C series account).
General Information
Honeywell's 7845i-GSM Internet communication module leverages Internet service (when
service is available) and transparently switches to GSM service when Internet service is not
available. When both services are unavailable, the 7845i-GSM module provides a third way
to communicate by sending a transmission via SMS (Short Message Service) also known as a
text message.
In normal operation (with Internet connectivity), the 7845i-GSM communicates from your
customer's network connection to the Honeywell Network Operations Center, (NOC) via the
AlarmNet-I network. The NOC receives data and routes the information to the Central
Station of your choice, based on the account number you assign to the module. Note that your
Central Station needs to give you the account number. The same account number is used for
both Internet and GSM transmissions. If your current Central Station is capable of receiving
signals from the Honeywell NOC, they are capable of receiving signals from the 7845i-GSM
module.
If, for some reason, Internet connectivity is not available, (for example, your customer's ISP
is off line or disconnected), the 7845i-GSM will transmit signals via the AlarmNet-G (GSM)
cellular network, which uses
the
GPRS (General Packet Radio Service) to complete these
transmissions. These transmissions are sent to the Honeywell NOC and then forwarded to
your Central Station exactly the same way as if they were received via the Internet.
