I am having a problem with my Gardtec 350. After entering the code to set the alarm the exit tone used to sound and then eventually go quiet. However now the exit tone just continues to sound. Will the system still be set? and is there any way to get the exit tone to how it was before? Any Advice would be appreciated.

Sounds as though it was programmed to set on final door, but it sounds as though the final door has developed an open circuit which is stopping the system from setting.

You`ll need to get the fault sorted, your system isnt setting.
