held in the Telguard database at the Communication Center for review and is
not forwarded on to the central station.
Programmable Supervisory Trip Output (STC) Relays
The Telguard TG-1 Express 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. It 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
to meet virtually any installation requirement.
The following supervisory features or combination of features are
programmable to trip the STC relay in order to meet a variety of installation
requirements:
Trips on no service condition (NSC).
Trips on radio communication failure condition (RFC).
Trips on low power failure (LPF).
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 Telguard Communications
Center (TCC)
Trips on c
atastrophic failure
(CF) if all power is lost.
Trips on
transmit-disable command
from the Communication
Center. This radio command disables only the Telguard transmitter
and would be used, for example, to shut down the Telguard due to a
runaway panel dialer.
Diagnostic and Status LEDs
Eight 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, and communication indicators. They
also can be used to provide a signal strength indication, similar to the signal
strength bars on a cellular phone. See the installation section for details.
