Figure 2. Wiring diagram:

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.
