On keypad art.01705 the warning “Control panel tamper” appears. What do I have to check?

First of all check that the two mechanical tampers (tear-proof and opening) on the control panel 01700/01703 are correctly closed.

If these tampers show any faults, try to exclude them by closing using the specific jumpers S1 (Tear-proof exclusion) and/or S2 (Opening exclusion).

Also remember that the “Control panel tamper” warning could also refer to a possible unbalancing on the Tamper  terminals (T, T) in the control panel and which are usually used to control the siren tampering. Therefore, check that the mechanical closing on these devices is correct.
