Tamper-Resistant Feature

• The detector base incorporates a tamper-resistant feature that prevents removal of the detector without the use of a small screwdriver or similar tool.
• To activate the feature, break off the tab on the detector base using needle-nose pliers (see Figure 4A), then install the detector.
• To remove the detector after activation, insert a small flat-blade screwdriver into the access hole on the side of the base and push the plastic lever away from the detector head (see Figure 4B). This releases the locking mechanism, allowing the detector to be rotated counterclockwise for removal.
• The tamper-resistant feature can be permanently disabled by removing the plastic lever from the base; however, once removed, the feature cannot be reactivated.
