FireNET FN-DAC Digital Alarm Communicator I & O Manual - v 1.0
•
Check wiring of the RJ31X jack(s). Be sure that the FN-DAC is connected
for proper line seizure.
•
Using the communicator phone line, make a test phone call to the receiver.
Listen for noise or distortion on the line. This can prevent proper
communication between communicator and receiver.
•
You may also wish to monitor the communication session using a telephone
test set in parallel with the phone line. This may help to determine why the
FN-DAC is having trouble communicating the information. Use caution when
working with phone lines, as ringing voltage may be 100 VAC!
Some Network Events are not being Reported
– The communicator will only report
events that are displayed on the panel where it is installed. If some network events are
not being reported, check the Network Interface programming to be sure that all events
are properly selected. See the
FireNET 4127 Installation and Operation Manual
for
more details on Network Interface configuration.
LEDs –
The Green LED (LED 2) flashes to indicate that the communicator is receiving power
and data. During normal operation this LED will flicker. At times it will not be lit, but it
should begin flickering again within 5 – 10 seconds.
If the Green LED is OFF –
•
Check for the presence of 24 VDC power at J7 (observe polarity)
•
Be sure the ribbon cable is securely plugged into J2 on the
communicator, and the PC port on the FireNET display board.
The Yellow LED (LED 3) lights when the communicator has seized a phone line to
report an event. When the communication session is finished, the yellow LED will turn
off. This is a visual indication that the communicator is attempting to report to the
monitoring station.
If the Yellow LED turns on and off repeatedly, it may be a sign that the communicator
is having trouble reporting to the monitoring station. Check to see that the monitoring
station is receiving all signals properly. If they are not, follow the steps above to
determine the problem.
The Red LED flashes on and off when there is an active modem connection to the
dialer. During normal mode, this LED may be on or off, but it will not be flashing.
