I have a Concept 6 alarm system (circa 1994) installed in my house. On a number of occasions it has alarmed and shown a tamper. Two weeks ago I disconnected connections 15 & 16 (tamper circuit) and put a service wire across them. This morning the alarm again sounded, showing a tamper.
Any assistance will be appreciated.

Some systems have a separate tamper circuit to the bell box not sure if yours does, but you should check the tamper return connections in the bell box .
