1.0 GENERAL DESCRIPTION AND OPERATION
The Telguard
model TG-5 is a digital cellular radio alarm transmission device used to provide a primary
transmission path (cellular) for control communicators (C/Cs). It uses the secondary transmission path
(telco) when the cellular path is not available. When transmitting an alarm signal, Telguard obtains its data
from the C/C by way of a telco interface. The device transmits a Link Request to the Telular operated
Communication Center and when a link acknowledgement is received, the Telguard handshakes with the
C/C and causes the C/C to transmit the alarm data. Telguard encodes the alarm data into SMS (Short
Messaging System) protocol and transmits to the local digital cellular network provider. The signal is
routed from the network provider to the decoding (message) center. The Communication Center performs
like a central station receiver and issues the transmission acknowledgement when the last message in the
transmission is received. After decoding and reformatting, the alarm signal is routed over telco to the
appropriate alarm company central station for action.
In a typical alarm installation, Telguard is installed in the same area as the host alarm system. The incoming
telco line is connected from any premises RJ-11 jack to Telguard and then from Telguard's RJ-45 jack to the
host control/communicator's digital dialer in the normal fashion. Two programmable supervisory trip (STC)
outputs are available for connection to the host control/communicator's trip zone input terminals in order to
provide a Telguard trouble signal to the C/C. Additionally, automatic self-test and status-on-demand report
signals are transmitted exclusively over the cellular network to the Communication Center. Telguard has its
own internal power supply/battery charger. All telco line and cellular monitoring, switching and supervisory
functions are built in--no extra modules are required.
Wireless voice calls may be made using POTS telephone equipment attached to the RJ-11 jack wired to the
WVL terminal block in the TG-5. The Telguard processes incoming and outgoing voice calls. When service is
available, the TG-5 generates a normal dial tone and when no-service or a non- registered cellular service is
found, a separate no-service tone is generated. The TG-5 maintains an open audio path when in a call or call
setup in order to receive progress tones and/or announcements provided by the cellular carrier or Telephone
Company when connected. Typical indications from the network may include:
• Subscriber-not-available announcement
• Audible ring tone (ring tone heard by calling party)
• Subscriber-busy tone
• System-busy tone (also known as reorder tone and congestion tone)
• Special-Information-Tone (SIT)
• Call-Waiting tone
• Action-acknowledgement tone
The TG-5 voice interface sends information to an external Caller ID device to allow presentation of the calling
party's telephone number if this service is available from the network. Both on-hook and off-hook caller ID are
supported.
The Telguard model TG-5 comes with a special digital cellular transceiver (without handset), dipole antenna,
interface with integrated control and power module, connecting cable, plug-in transformer and comes in a
standard metal enclosure. It is UL Listed for residential burglary and residential fire.
The Listed equipment at the Telular operated Communication Center (TCC) plays a key role in the operation of
every Telguard. All Telguard units are required to use the Communication Center because of the C/C alarm
signal format encoding and decoding requirements used in packet-data transmissions over the digital cellular
network . The Communication Center also manages the real-time databases for cellular activation and a
complete history of every Telguard's operating conditions. These conditions include programming setup
information, cellular alarm transmission information, supervisory trouble information, status-on-demand
information, and automatic self-test information.
