WIRINg INSTRUCTIONS
NOTE: Refer to 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 the bare wire end under the clamping plate,
and tighten the clamping plate screw. Use the strip gauges molded into the
inside and underside of the base for ease of wiring to terminals 1 and 4, and
to terminals 6 through 14, respectively.
The zone wiring of the detector base should be checked before installing the
smoke detector heads. The base contains a built-in shorting spring to make
this possible. After the detector base is wired and mounted to an electrical
box, position the shorting spring against terminal 3. This temporary connec-
tion energizes the supervisory relay and permits the wiring of the loop to be
checked for continuity.
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
This detector base also includes an optional tamper-resistant feature that
when activated prevents removal of the detector without the use of a tool.

Department, RA #__________, 3825 Ohio Avenue, St. Charles, IL 60174. Please include a
note describing the malfunction and suspected cause of failure. The Company shall not
be obligated to repair or replace units which are found to be defective because of damage,
unreasonable use, modifications, or alterations occurring after the date of manufacture.
In no case shall the Company be liable for any consequential or incidental damages for
breach of this or any other Warranty, expressed or implied whatsoever, even if the loss
or damage is caused by the Company’s negligence or fault. Some states do not allow the
exclusion or limitation of incidental or consequential damages, so the above limitation
or exclusion may not apply to you. This Warranty gives you specific legal rights, and you
may also have other rights which vary from state to state.

To make the base tamper resistant, simply break off the tab on the base (see
Figure 4A), before installing the detector.
To remove the detector from the base after it has been made tamper resistant,
insert a small screwdriver (see Figure 4B) into the small hole and press the
plastic lever away from the detector. Rotate the detector counterclockwise and
remove.
NOTE: Head removal after activating the tamper-resistance feature first re-
quires removal of the decorative ring.
