No messages are being received from the Communicator
1. Verify active alarms are not defined as disable state (refer to Setting the test schedule, page 20).
2. Go over the contact group, make sure the users are not set to 'idle' (refer to Adding names to the
Address Book, page 22) and that the contact information is entered correctly.
3. Verify that the controllers are functioning properly (meaning are transmitting alarms or
messages).
Alarm LED is ON but the siren does not operate

Line modem
‘No dial tone' alarm
1. Verify that there is a line by using a phone connected to the phone jack.
2. Perform PHONE LINE VOLTAGE test, (

3. If it is above 40 V, connect a regular phone for testing.
4. If the line is not operating, check with your service provider.
5. If the line is operational, perform power cycle for Communicator (turn device off and then back
on). Allow a few minutes until the Communicator recovers.
Dial Out is not functioning
1. Insert extra delay by adding commas (refer to Configuring the dial delay, page 29).
2. If you have an ADSL modem on the same line, verify that your ADSL line filter meets your service
provider’s specifications (high quality line balanced).
