Any changes that you or a tech made that may have triggered an issue?
The Alarm will report a problem if it is not communicating with the network if it is not retorting a problem then the TL280 receiver may have been disabled.
The TL280 has Communicator Status LED's that indicate error situations have a look at these and correlate them to the TL280 manual.
I have had the following issues previously:
- Electrician wired a data cable 1 is to 1 as in not to T568A or T568B spec the TL280 didn't like this
- Alarm tech wired the ribbon cable to the TL280 from the main alarm board inverted
- The TL280 receiver board was disabled in the Alarm setup
- Change of any of the Installation Info in the TL280 Control 4 Driver
- Change in the IP Subnet while the TL280 has a Static IP Address
Hope this helps.
