SilentKnight B224BI 6 Mounting Base w/Built-in Isolator - Manual (Page 2)

WIRINg INSTRUCTIONS
Make wiring connections by stripping about
3 ⁄
8
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 2 and 3). Ter-
minal 4 is for shielded cable only (see Figure 2). If shielded cable is used, the
shield connection to and from the detector must be continuous by using wire
nuts, crimping, or soldering to ensure a reliable connection. If shielded cable
is NOT used, leave terminal 4 in the screwed-down position.
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.

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 4A. 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 in the side of the base
and push the plastic lever away from the detector head (see Figure 4B). This
allows the detector to be rotated counterclockwise for removal.
NOTE: Head removal after the tamper-resist feature has been activated re-
quires removal of the decorative ring.
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.
