1.0 GENERAL DESCRIPTION AND OPERATION
The Telguard

is a cellular radio alarm transmission device, which is used to provide a backup transmission path
(cellular) for control communicators (C/Cs) in case the primary transmission path (telco) is not available. When
transmitting over cellular, 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
digital packet data protocol and transmits on one of twenty-one available control channels used by the local AMPS
cellular network provider. The signal is routed from the network provider through the Aeris virtual network system to
the decoding (message) center. The Communication Center performs like a central station receiver and issues the
transmission kiss-off 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.
Telguard is compatible with most control/communicators and no special equipment is needed at the premises or in the
alarm monitoring station. All Telguard programming is done with a standard touch-tone telephone or lineman’s buttset
and Telguard can be installed wherever cellular service is available. Different dialing patterns between telco and
cellular, cellular area code changes and PBX access numbers are not a problem for installers. Fraud and cloning
problems are eliminated since all transmissions occur over the cellular control channels in packet-type data format
and never over any voice channels.
In a typical alarm installation, Telguard is installed in the same area as the host alarm system. The incoming telco line
is connected from the RJ31X to Telguard and then to the host control/communicator's digital dialer in the normal
fashion. A programmable supervisory trip (STC) output is 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.
All models are capable of transmitting an automatic self-test signal to the central station on a daily, weekly, or monthly
schedule. 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.
All Telguard models come with a special Microburst™ compatible 3-watt cellular transceiver (without handset),
antenna, interface with integrated control and power module, connecting cable, and plug-in transformer. The installer
to provide backup times that range from twenty-four to seventy-two hours must supply a rechargeable 12V battery,
7.0AH or 14.0AH. Type of enclosure and type of antenna included are the only differences among the three models
available. Economy model T100C001, UL Listed for Supplemental Use only, comes in a flame-retardant plastic
enclosure (9½in.x4½in.x1¾in.) with whip antenna. Model T200C001, UL Listed for residential and commercial fire,
as well as residential burglary, comes in a standard metal enclosure (12in.x12in.x3½in.) with keylock and magnetic
mount antenna with 12ft. of cable. Model T300C001, UL Listed for all residential burglary and fire, commercial
burglary and fire, and bank applications comes in an attack-resistant enclosure with keylock, tamper switch, and
magnetic mount antenna.
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 cellular network control channels.
The Communication Center also manages the real-time databases for cellular activation, airtime, billing, installation
site location, 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. This information is made available to authorized personnel through
Telular's Interactive Voice Response System (IVR), Telular's computer access Communication Center Intranet System,
or though Telular's Customer Service Center.

The Telguard is a cellular radio packet transmission device that is installed at the protected premises to
provide alarm transmission integrity for security systems. It is used to provide a backup transmission path
