LYNXDM-GSM/LYNXDM-IGSM
COMMUNICATIONS MODULES
INSTALLATION AND SETUP GUIDE
SYSTEM OVERVIEW
Introduction
The LYNXDM-GSM and LYNXDM-IGSM are desk or wall mounted communications modules for the LYNXR-I
Series control panel. Each module is equipped with an integral AlarmNet 7845GSM Digital Cellular or 7845-
iGSM Internet Communication Module with Remote Services. 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.
The LYNXDM-GSM and LYNXDM-IGSM modules require an AlarmNet–i account. For new installations,
please obtain the account information from the central station prior to programming this module.
General Information
LYNXDM-GSM
Honeywell's LYNXDM-GSM cellular communication module transmits signals via the AlarmNet-G network
(GSM cellular network), using GPRS and forwards them to your Central Station. If the GPRS network is
unavailable, the LYNXDM-GSM (if enabled by the dealer) will attempt to send the transmission via SMS
(Short Message Service and/or e-mail).
LYNXDM-IGSM
Honeywell’s LYNXDM-IGSM Internet communication module communicates from your customer’s network
connection to the Honeywell 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. The
same account number is used for both Internet and GSM transmissions. If, for some reason, Internet
connectivity is not available (for example, your customer’s ISP is off line or disconnected), the LYNXDM-IGSM
will transmit signals via the AlarmNet-G (GSM) cellular network, using GPRS. 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.
If the Internet AND GPRS are both unavailable, the LYNXDM-IGSM will attempt to send the transmission via
SMS, also known as a text message. If all three methods fail, the module will attempt to deliver the alarm until
the alarm time expires. Once the old alarm time has expired, the alarm is dead and will not be delivered.
About AlarmNet-I Internet Application
AlarmNet-I is a fully encrypted, secure method of delivering alarm messages from a protected premise to an
AlarmNet equipped central station. An Internet Communicator Module transmits status, supervisory, and
alarm messages to the AlarmNet Control Center using a broadband Internet connection. The AlarmNet Control
Center identifies, validates, and forwards the messages to the appropriate AlarmNet central station.
Encryption
The LYNXDM-IGSM 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
globally unique identifier called a MAC number, and a large random number or KEY. This KEY and MAC
number are also stored in the AlarmNet servers. When a device contacts AlarmNet, it sends the MAC number
in the clear followed by the message that is encrypted using the KEY data. The server looks up its copy of the
KEY based on the MAC number and uses that KEY to decrypt the message.
The LYNXDM-IGSM uses 256 bit AES (Rijndael) encryption (which is required for certain government
installations). The AlarmNet-I AES Encryption Software Module Version 1.0 contained in the Honeywell
products has NIST approval. Listings for this approval can be found at
