Telguard to upload current operational status data and historical data, just as the automatic self-test
described above, except that the query signal is controlled by the one who initiates it. The query
signal is held in the Telguard database at the TCC for review and is not forwarded on to the central
station.

The Telguard has two supervisory relay trip outputs (STC1 normally open and STC2 normally
closed) and both are energized in a powered-up state when no system troubles exist. This enables a
supervisory trouble code to be transmitted to the central station when connected to an alarm panel’s
24-hour instant input zone. The STC relays are programmable, using
www.Telguard.com
, to meet
virtually any installation requirement.
The following supervisory features or combination of features are programmable to trip the STC
relays in order to meet a variety of installation requirements:
Trips on AC fail condition (ACFC)—or Low Power Failure (LPF) if powered from a DC
source.
Trips on low or missing battery condition (LBC).
Trips on no service condition (NSC).
Trips on line fault condition (LFC).
Trips on radio communication failure condition (RFC).
Trips on dial tone failure(DTF)
The following system trouble features are embedded in the Telguard for tripping the STC relay and
cannot be changed:
Tripped when unit is not activated at the TCC
Trips on c
atastrophic failure
(CF) if all power is lost.
Trips on
transmit-disable command
from the TCC. This radio command disables only the
Telguard transmitter and would be used, for example, to shut down the Telguard due to a
runaway dialer.

Six active LEDs are provided as a useful aid during installation and give installers an immediate
visual indication of system status. The LEDs serve as indicators for activation, system trouble
conditions, AC power, and communication indicators. They can also be used to provide a signal
strength indication, similar to the signal strength bars on a cellular phone. See the installation
section for details.

TG-4 can be operated solely by DC Power Source (for example, power coming from the alarm
panel’s auxiliary output). This will eliminate the need for a separate AC outlet at the protected
premises. Connect the panel power to DC Input and ground on the TG-4 and the TG will
operate normally. Telguard‘s operational range is 6.2V - 16V DC.
Note: When using DC power, the Telguard should not be connected to a battery or AC
power source. Because there is no AC connection, the AC LED will be OFF when operating
in DC mode. Battery will not charge on DC power.
