when my wireless siren stoped working i replaced the battery and now the siren will not sound when an alarm has been activated.

when i carry out a diagnostic it will see the siren and says the signal is strong, but when i try to activate the siren by opening the door the siren will not sound.

if i press the test button on the inside of the wireless siren it will sound.

this may all coinside with a power cut that i had a few weeks ago around about the same time.

does anone have any ideas of what to do next ?

Reprogramme the siren into the system, it will ask you to delete the 1st one, do so then enrol the same again.
