Recently an eletrical storm lightning strike damaged telephone adaptor equipment and also my alarm system.

Scantronic 9200 alarm now internal alarm keeps sounding every few minutes and can't be stopped with disconnecting the internal connection. Has the main board been damaged or is something else damaged. How can I fix it

if its a monitored system then kiss your panel bye bye,
although the master phone socket has a lightning arrester,in our exper.it dosent work,
