Appendix 3 Commercial Fire Single DACT Installation
The TG-7FE is suitable for use as a sole path cellular communicator. The TG-7FE can also be utilized
as a dual path option that replaces both Telco requirements by the panel. By following Telguard's
installation guidelines, the installer can provide the best conditions for a stable, sole path or dual
path connection. In order to ensure that the cellular path to be used for signaling has the highest
reliability possible, it is necessary to confirm two additional conditions, beyond what is outlined
above.
TG-7FE Cellular Signal Strength
Installation instructions for the Telguard TG-7FE indicate that a cellular signal strength of -90dBm
(RSSI LEDs 4 and 5 on, with LED 3 flashing) i
, an
additional level of signal integrity will minimize false alarm supervision failures caused by
interference and atmospheric fading. Because of this, it is always recommended that the device
should be installed in a location that provides the best signal strength possible.
Configure Fire Alarm Panel to Use Single Communication Device
Fire panels are typically provided with two Telco connections in order to provide multiple reporting
paths. With the TG-7FE having a single RJ-45 jack for connecting to the panel, one of these DACT
connections is not necessary for UL 864 and ULC-S559 compliance. However, the panel will
continue to supervise that unused line unless changes are made at installation time.
There are two methods for removing supervision alarms at the panel caused by disconnecting the
second Telco connection. Either method can be used.
1.
Disabling the Second Telco Connection
Some fire panels have a configuration mechanism to disable the second Telco connection. Once the
second Telco connection is disabled, the panel will no longer supervise the connection. This is the
preferred method of removing supervision alarms at the panel caused by removal of the second
Telco connection.
2.
Connecting the Telco Connections Together
The Telguard communicator is capable of providing dial tone to both Telco connections, if the Telco
connections are connected together, s
in a household are connected together. If this method is used, the installer must take care to
ensure that dual path reporting is not enabled on the panel, or else simultaneous alarm reports
from the two Telco connections may interfere with each other.
Test the communicator thoroughly when using this method. Verify the panel does not report
problems with the second line, especially when the panel is reporting to the central station.
