– Fixing holes metal box
To guarantee the opening and removal protection, a wall plug must be inserted in the hole of the tamper
protection to signal attempts to open the control unit and trigger the protection if an attempt is made to
remove the box from the wall. The screw inserted in the wall plug must protrude approx. 51 mm from the
bottom of the metal box to be able to act on the microswitch lever that only pivots on the fixing pin to
guarantee the removal protection function. Removal protection is compulsory to guarantee EN 50131
Grade 3 certification.
The tamper function can also be installed to provide anti-opening protection only. In this case, the system
does not comply with EN 50131 Grade 3 certification.
