A label is affixed to the base for recording the zone, ad- dress, and type of detector being installed at the base loca- tion. This information is useful for setting the detector head address and for verification of the sensor type required for that location.

Once all detector bases have been wired and mounted, and the loop wiring has been checked, the detector heads may be installed in the bases.

Tamper-resist Feature

NOTE: Do not use the tamper-resist feature if the removal tool is to be used.

This detector base includes a tamper-resist feature that pre- vents its removal from the base without the use of a tool.

To activate this feature, break the tab from the detector base as shown in Figure 3A (see page 4). Then, install the detector.

To remove the detector from the base once the tamper-re- sist feature has been activated, insert a small-bladed screw- driver into the slot in the side of the base and push the plastic lever away from the detector head (see Figure 3B, page 4). This allows the detector to be rotated counter- clockwise for removal.

NOTE: Head removal after the tamper-resist feature has been activated first requires removal of the decora- tive ring.

The tamper-resist feature can be defeated by breaking and removing the plastic lever from the base. However, this pre- vents the feature from being used again.
