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
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
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
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.
