of an inch (10 mm) of insula-
tion from the wire end. Then, insert the wire into the appropriate terminal and
tighten the screw. Wire the communication line in (+) to terminal 1. Insert
both communication line in (–) and communication line out (–) to terminal 2.
Wire communication line out (+) to terminal 3 (see Figures 3 and 4).
A label is affixed to the base for recording the zone, address, and type of
detector being installed at the base location. This information is useful for set-
ting the detector head address and for verification of the sensor type required
for that location.
Once all detector bases have been wired and mounted, and the loop wiring
has been checked, the detector heads may be installed in the bases.

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 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, Returns

TAMPER-RESIST fEATURE
NOTE: Do not use the tamper-resist feature if the removal tool is to be used.
This detector base includes a tamper-resist feature that prevents its removal
from the base without the use of a tool.
To activate this feature, break the tab from the detector base as shown in Fig-
ure 5A. Then, install the detector.
To remove the detector from the base once the tamper-resist feature has been
activated, insert a small-bladed screwdriver into the slot from the top and
press down on the lever (see Figure 5B). This allows the detector to be rotated
counterclockwise for removal.
The tamper-resist feature can be defeated by breaking and removing the plastic
lever from the base. However, this prevents the feature from being used again.
