Appendix C: Commercial Fire Signal DACT Installation

IntelliCom Advanced Gateway is suitable for use as a dual path cellular communicator that replaces both Telco requirements by
the panel. By following the IntelliCom installation guidelines, the installer can provide the best conditions for a stable, sole path
or dual path connection. 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.
IntelliCom Cellular Signal Strength
Installation instructions for the IntelliCom Advanced Gateway indicate that a cellular signal strength of -90dBm (RSSI
LEDs 4 and 5 on, with LED 3 flashing) is sufficient. While this is suitable for normal use, 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.
DACT Panels - 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
IntelliCom having a single RJ-45 jack for connecting to the panel, one of these DACT connections are not necessary
for UL 864 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 IntelliCom Advanced Gateway can provide dial tone to both Telco connections, if the Telco connections
are connected together, such that TIP is connected to TIP and RING is connected to RING. The two connections
will receive dial tone in much the same way that multiple extensions 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 IntelliCom thoroughly when using this method. Verify the panel does not report a trouble condition with
the second line, especially when the panel is reporting to the central station.
