the initial account activation is done, the installer must verify the Link Supervision by turning off the device
and making sure an alarm with the specific code is delivered.
WARNING: Standard Line Security has only been evaluated between the TG-7 and the TCC. It is the
responsibility of the installer to verify Standard Line Security from the Listed alarm panel to the Listed
receiver through the TG-7 models as marked on the alarm panel and as indicated in the manufacturer's
installation instructions
.
Please note that Link Supervision is supported by all TG-7 models. However, only TG-7FS and TG-KIT
models have the UL Listing for Commercial Fire applications.
Complete Power Supervision
The TG-7 series device can supervise and report status of the backup battery and AC power source. The
Telguard unit has an integrated control and power module which also keeps the Telguard unit battery
charged. This battery charger function is also supervised.
Low/Missing Battery Condition (LBC)
When using AC as the main power source, the Telguard device checks the backup battery voltage on initial
power-up and every 60 seconds thereafter. If the battery voltage is less than 11.6 volts, it changes from
‘good’ to ‘bad’ state and a LBC
occurs whereby the STC LED blinks twice, and the STC relay trips. When the
battery voltage increases to 12.1 volts, the STC LED and STC relay restore. The Telguard device also
indicates Low/missing Battery Condition (LBC) when the battery charger fails, or the battery fails the
periodic load test.
AC Failure Condition (ACFC)
AC failure condition (ACFC) is detected immediately when the AC power drops below 102 VAC. When this
condition is detected, the STC LED blinks once, the AC Power LED turns off, and the STC trip output is
activated after a preset time (default 2 hours). When AC power returns to normal (
106 VAC), the AC Power
LED turns on immediately and the STC trip output restores after 60 seconds.
Note: If the Telguard device is being powered through its DC connection, a Low Power Failure (LPF) will
occur if the DC power into the TG-7 unit drops below 5.1VDC and restore after reaching >5.6VDC. LPF
will present itself in the same manner as the ACFC.
Dial Tone Failure (DTF)
The Telguard provides a voltage supply and other signaling to the panel like a telephone central office. The
Telguard device continuously monitors the 30V supply circuit that provides dial tone to the alarm panel. A
Dial Tone Failure (DTF) occurs when unable to provide proper telephone signaling to the panel (30V supply
drops to 20V or less while the alarm panel is on-hook). The STC LED will flash 6 times and the STC relay will
trip.
Note: This condition will require contacting Telguard Technical Support for resolution.
Catastrophic Failure (CF)
Catastrophic Failure (CF) is any condition that causes the Telguard device to stop functioning at all levels.
The most common CF is AC power failure followed by a complete discharge of the backup battery. The STC1
and STC2 trip outputs are activated and the visible indication is loss of all LED activity. Total loss of power to
the Telguard device
does not prevent transmission of alarm messages from the alarm panel “through” the
Telguard unit and out over an operative phone line.
Telguard Automatic Self-test Report
The automatic self-test signal schedule is programmable as prescribed when the Telguard device is
registered. The central station receives the automatic self-test report in the same format that the alarm
panel normally uses for communication over the Telco line. The self-test code and testing frequency are set
