Once all the detector bases have been wired and mounted,
and the loop wiring has been checked, the detector heads
may be installed in the bases. The shorting spring in the
base will disengage automatically when the detector head
is removed from the base. DO NOT remove the shorting
spring since it reengages as the detector head is turned into
the base, completing the circuit.
Tamper-resistance Feature
NOTE: Do not use the tamper-resistance feature if the XR2
removal tool is to be used.
The tamper-resistant tab, in the detector mounting bracket,
can make the detector tamper-resistant by making it neces-
sary to use a small screwdriver or similar tool to detach the
detector from the bracket.
To make the detector tamper-resistant, use needle-nose pli-
ers to break the smaller tab at the scribed line on the tamp-
er- resistance tab. Figure 3A shows the location of this tab
on the detector mounting bracket.
To remove a detector from the bracket after it has been
made tamper resistant, use a small screwdriver or other
similar tool, to depress the tamper-resistance tab in the slot
on the mounting bracket, and rotate the detector counter-
clockwise (see Figure 3B).
NOTE: The decorative ring must be removed before the
smoke detector can be detached from the base
after the tamper-resistant capability is enabled.
