Tamperproof Feature
NOTE: Do Not use the tamper-resistant capability if the
XR2 or XR2B Removal Tool will be used. This detector
base also includes an optional tamperproof feature that
when activated prevents removal of the detector without
the use of a tool.
To activate this feature, simply break off the tab on the
detector base shown in Figure 3A, and install the detector.
To remove the detector from the base once the tamperproof
feature has been activated, place a small-bladed screwdriv-
er into the small hole on the side of the base and push the
plastic lever away from the detector head (see Figure 3B).
This will allow the detector to be rotated counterclockwise
for removal.
The tamperproof feature may be defeated by breaking and
removing the plastic lever from the base, however this pre-
vents ever using the feature again.
Remote Annunciator (RA400)
The remote annunciator is connected between terminals 1
and 3 using the spade lug terminal packed with the remote
annunciator. The spade lug terminal is connected to the
base terminal as shown in Figure 4.
It is not acceptable to have three stripped wires under the
same wiring terminal unless they are separated by a wash-
er or equivalent means. The spade lug supplied with the
model RA400 is considered an equivalent means. See
Figure 2 for proper installation.
