I've installed this system over 2 months ago and over the last few days I've been getting a tamper warning bell box (Deltabell E). Both the siren and panel sounded. So I checked the Deltabell Microswitch and adjusted the back tamper screw on the bell box. All was ok for 24 hours
However this morning the panel sounded with out the external bell box sounding.
Log indicates input 33 tamper bell box with a amber fault warning on panel flashing.
To get around this I deleted input 33 and the panel warning light had gone . However this cannot be the solution to the problem. Help please.
