and the STC relay will trip as programmed. Restoral of this condition occurs after 10 minutes or when
a message is received from the TCC.
NOTE: When End-to-End acknowledgment feature is enabled, a message that fails to deliver to the
Central Station will trigger an RFC condition.
Panel Presence Failure (PPF)
Panel presence failure condition (PPF) occurs when the communicator is unable to detect the
presence of the alarm panel. PPF is indicated by the STC LED flashing 7 times. A supervisory report is
generated and sent to the TCC for Central Station delivery upon detection of PPF. Restoral of this
condition occurs when the alarm panel is detected as present for the selected delay time.
NOTE: The factory default for PPF is Disabled and needs to be Enabled for its use. For the PPF
feature to work, Tip, Ring, and the return connections for Tip and Ring must be connected
between the panel and the communicator.
UL/ULC Compliance Note:
If the wiring distance between the panel and the communicator is
greater than 20 ft. (18m or in different rooms in Canada) or the connection is not mechanically
protected (metal conduit required in Canada), PPF must be enabled. Since fire systems must
comply with these restrictions (UL 864, ULC-S559), PPF is not required for fire systems.
Control Failure to Communicate (CFC)
The Control Failure to Communicate (CFC) feature allows the Telguard unit to monitor the number of
communication attempts the alarm panel makes over Telco before the unit becomes the main path of
communication. This feature works by monitoring the alarm panel from the time it goes off-hook and
attempts to communicate, to on-hook status, and comes off-hook again. Each change in state by the
alarm panel from off-hook to on-hook to off-hook again is considered an attempt. If this continually
happens for a specified number of times within a specific time period, the unit seizes the line and
takes over as the main communication path for the alarm panel. If the unit goes into CFC, then it will
not allow the panel to communicate via Telco again until the panel has been on-hook for 10
consecutive minutes.
Note that the CFC condition causes the Telguard unit to redirect communications to the cellular
channel, but it is not indicated on the STC LED, nor does it cause the external relays to be tripped.
Note: The factory default for CFC is Disabled and needs to be Enabled for its use. When the unit
is configured as the Sole Path, the CFC function is not applicable.
Link Supervision and Standard Line Security
In order to satisfy UL and ULC requirements, the communicator can enable link supervision at preset
intervals. When this feature is enabled, TG-7 Cellular Series communicators also meet the
requirements for Standard Line Security when used with a UL Listed compatible alarm panel. Once
the communicator is provisioned with the Link Supervision option, the TCC constantly monitors all the
enabled communicator pathways and sends a specific message to the Central Station if a path is
broken or a compromise attempt is made. After the initial account activation has completed, 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 communicator 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 communicator as marked on the alarm panel and as
indicated in the manufacturer's installation instructions
.
