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

/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.

System Sensor warrants its enclosed smoke detector base to be free from defects in mate-

rials and workmanship under normal use and service for a period of three years from date

base. No agent, representative, dealer, or employee of the Company has the authority 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 manufacture.

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

THREE-YEAR LIMITED WARRANTY

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.
