If the base is being installed in a zoned system, check the
zone wiring before installing the smoke detector head. The
built-in shorting spring makes it convenient to do this.
After the detector base is wired and attached to the electri-
cal box, position the shorting spring against terminal 3. Use
the slot in the retaining clip to hold the spring against the
terminal, as shown in Figure 1. This shorts the negative-in
and negative-out leads so that loop wiring can be tested for
continuity. Do NOT remove the shorting spring from the
base when continuity tests are completed.

After all detector bases have been mounted, wired, and the
wiring checked, install the detector heads. The shorting
spring in the base automatically disengages 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
System Sensor XR2 Removal Tool will be used to
remove detectors from the base.

This detector base can be made tamper resistant so the
detector cannot be detached without the use of a tool. To
make the base tamper resistant, break off the smaller tab at
the scribed line on the tamper-resistance tab, on the detec-
tor mounting bracket (see Figure 4A), before installing the
detector. 

To remove the detector from the base after it has been made
tamper resistant, remove the decorative ring by rotating it in
either direction and pulling it away from the base. Then,
insert a small screwdriver (Figure 4B) into the notch and
press the plastic lever toward the mounting surface. Rotate
the detector counterclockwise and remove.
