Verify everything before the installation
Remove the SC/SCM cable/mat, control, and sensor from their packages. Inspect them for any visible damage and verify everything is the cor-
rect size and type according to your plan. Do not attempt to install a damaged product.
Record the cable/mat information on the Cable/Mat Testing Log on page 19 . Give this information to the homeowner to keep in a safe place.
The cable/mat model number, serial number, voltage, and resistance range are shown on a nameplate label attached to the power leads.
Do not remove this nameplate label. The electrical inspector will need to see this.
Important
Before installing the FC/FCM cable/mat, make sure to fully check out the products, and carefully plan your site. The following steps may not
necessarily occur in the order shown, depending on contractor and electrician scheduling and variations in site preparation requirements. A
good discussion with all parties involved will help eliminate costly errors and damages.
Measure the resistance
 Use a digital multi-meter to measure the resistance between the conductors of the mat power leads. Record these resistances on the
Cable/Mat Testing Log under section “Test Record # 1 Prior to Installation”. The resistance between the white and black lead wires
should be within the resistance range on the nameplate label. If it is a little low, it may be due to low air temperatures or meter calibration.
Consult the factory if you are in doubt.
 The resistance between the white and black leads and ground lead should be “open”, usually indicated by an “OL” or whatever your meter
shows when the test leads and ground lead should be “open”, usually indicated by a reading. Record this information and contact the facto-
ry before installing. This could indicate damage, test lead problems, or a number of other issues. Try “pinning” the test leads to the cable/
mat lead wires against a hard non-metal surface if your readings fluctuate.
 Your electrician should perform an insulation resistance test on the mat. A mega ohm meter adjusted to a minimum 1000 VDC should give a
measured value at least 20 mega ohm (MΩ).
Mega Ohm meters apply high voltage and could shock or cause serious injury if improperly used.
Follow mega ohm meter instructions for safe and proper use.
IMPORTANT! Use King’s Cable Alarm Monitor during installation.
 It is recommended to use the King’s Cable Alarm Monitor (Model # FCS11) during installation. When con-
nected, the device will constantly monitor the heating wire during the entire installation process. If the
wire is cut or damaged during installation, this device sounds an alarm. The FCS11 will prevent burying a
damaged wire below hardened concrete.
