System Overview

Congratulations on your purchase of Honeywell's GSMBR or iGSMBR Communications
Module (referred to as the communications module). The communications module easily
connects to your security system's control panel and sends alarms and messages to AlarmNet
for subsequent transfer to you central monitoring station.
The communications module requires an AlarmNet account. For new installations, please obtain the
account information from the central station prior to programming this module.
The GSMBR communicates with AlarmNet using GSM (Global System for Mobile)
technology utilizing GPRS (General Packet Radio Service) as a means of data transfer. If the
GPRS part of the GSM cellular network is unavailable, it will attempt to send a transmission
via SMS (Short Message Service) also known as a text message.
The iGSMBR communicates with AlarmNet first via the internet, and only uses GSM as
backup communications when internet service is down.
In addition to sending alarms and messages, the communications module provides a means
of uploading and downloading of data from the control panel.


Basic features of the communications module include:
Reports fire, burg, and status messages.
GSMBR reports messages via GSM.
iGSMBR reports messages via the internet first, and reports via GSM as backup when
Internet reporting is not available.
iGSMBR easily connects to a hub or router, and installs behind firewalls without
compromising network security. Further it supports dynamic or static IP addressing.
Easy connection to compatible Honeywell control panels.
Simple programming using a 7720P programming tool.
Allows uploading and downloading of control panel data.
Supports remote control of the alarm system via Remote Services.

Data Encryption

The communications module supports private key encryption. Private Key encryption means
that both the sender and the receiver know the KEY used to encrypt the data. Each device
produced by Honeywell is loaded with a unique identifier called a MAC number, and a large
random number or KEY. This KEY and MAC number are also stored in the AlarmNet
When a device contacts AlarmNet, it sends the MAC number followed by the message that is
encrypted using the KEY data. The server looks up the MAC number and uses the KEY
associated with it to decrypt the message.
