General Description and Operation
The Telguard
TG-1 (Part # TG1LA002B) is a digital cellular radio alarm
transmission device used to provide a primary transmission path (cellular) for
Household alarm panels.
When transmitting an alarm signal, the Telguard obtains its data from the Household
alarm panel by way of a telephone interface. The Telguard will obtain all alarm
signal information including monitoring station phone number, account number and
all zones for every alarm transmission. The Telguard handshakes with the alarm
panel causing it to transmit the alarm data.
The Telguard encodes the alarm data
and transmits to the Telguard Communication Center (TCC) over the digital cellular
network.
The TCC performs a function similar to 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 to the
appropriate alarm company monitoring station for action.
In a typical alarm installation, the Telguard is installed in the same area as the
Household alarm panel and is connected directly to the Household alarm panel via
Telguard's RJ-45 jack.
Two programmable System Trouble Condition (STC) relays
provide supervisory trip outputs for connection to the alarm panel’s trip zone
input terminals in order to provide a Telguard trouble signal to the alarm panel.
Additionally, automatic self-test and remote query signals are transmitted
exclusively over the cellular network with all Telco line and cellular monitoring,
switching and supervisory functions built in.
No extra modules are required. The
Telguard has its own power supply which keeps the Telguard battery charged.
The UL Listed equipment at the TCC plays a key role in the operation of every
Telguard.
All Telguards utilize the TCC due to the panel alarm signal format
encoding and decoding requirements used in packet-data transmissions over the
digital cellular network.
The TCC also manages the real-time databases for
cellular accounts and a complete history of every Telguard’s operating conditions.
These conditions include programming setup information, cellular alarm transmission
information, supervisory trouble information, remote query information, and
automatic self-test information.
