System Sensor B114LP - Manual (Page 2)

WIRINg INSTRUCTIONS
NOTE: Refer the manufacturer’s instructions for releasing device wiring.
NOTE: To ensure that electrical connections are supervised, do NOT loop
wires under terminals 8, 9, 10, and 11 - cut the wire at each terminal.
To make electrical connections, strip approximately 3 /
8
inch (1 cm) insulation
from the end of each wire. Slide a wire under the clamp plate on each side of
the terminal screw and tighten the screw.
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 con-
venient 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 disen-
gages 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 de-
tached 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.
