3.1 Tamper Requirements
To meet U.L. requirements, a U.L. Listed tamper switch must be in-
stalled in the single gang box used for mounting the keypad. The
tamper switch must activate if the keypad is removed from the box
and must disconnect power from the lock. The lock must be a fail-
secure device, meaning the lock remains locked when power is re-
moved. In addition, once the tamper device is activated, it must be
configured so that it can only be reset from within the protected
area. Only a Sentrol 3012 or Sentrol 3025T tamper switch can be
used. The diagrams on the next page show the suggested mount-
ing location for each device.
