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 headPiLsAtSuTrICnLeEdVEinRto the base,
completing the circuit.

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.

Three-Year Limited Warranty
System Sensor warrants its enclosed smoke detector base to be free from defects in ma-
terials and workmanship under normal use and service for a period of three years from
date of manufacture. System Sensor makes no other express warranty for this smoke
detector base. No agent, representative, dealer, or employee of the Company has the au-
thority to increase or alter the obligations or limitations of this Warranty. The Company’s
obligation of this Warranty shall be limited to the repair or replacement of any part of the
smoke detector base which is found to be defective in materials or workmanship under
normal use and service during the three year period commencing with the date of manu-
facture. After phoning System Sensor’s toll free number 800-SENSOR2 (736-7672) for a
Return Authorization number, send defective units postage prepaid to: System Sensor,
Repair 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
