NFORMATION
All versions of the GSM and Ethernet Alarm Communicator, operate on a GSM network and are housed inside the Self Contained
Wireless Alarm System Model SCW9055/9057. The Communicators use an Internal Antenna only.
Each version of Alarm Communicators covered by this Installation Manual are described below:
GS2055:
A High Speed Packet Access/Global System for Mobile (GSM) wireless Alarm Communicator that sends alarm communication to
Sur-Gard System I, II, III (SG-DRL3IP), and IV (SG-DRL4IP) central station receivers via a GSM digital cellular network.
TL255GS:
Is a dual-path Cellular/Ethernet Alarm Communicator that sends alarm communication to Sur-Gard System I, II, III, and IV
central station receivers through Ethernet/Internet or a GSM digital cellular network.
The dual path Communicator can be used as either a backup or primary Communicator. The Communicator supports Internet Protocol
(IP) transmission of panel and internal events over Ethernet/Internet and/or GSM.
For North America the following model names are available:
GS2055-NA
and
TL255GS-NA
.
CAUTION
:
• Do not stay close to the equipment during device operation and to do not touch any exposed wires and other conductive surfaces,
• Recycle the battery according to the local rules and regulations.
NOTE:
Prior to installation of the
GS2055
or
TL255GS
Communicator, confirm with your local carrier that the GSM network is avail-
able and active in the area where the Communicator will be installed, and that the location provides a radio signal strength that
is adequate for uninterrupted service.
