LC1000 INSTRUCTION MANUAL WIRING
PAGE 26
5. The alarm console is separated into two wiring sections, for each printed circuit board, by an
aluminum cover. The wiring and terminal block on the left side are intrinsically safe and are
physically separated from the AC power wiring on the right side. This separation must be
maintained. Remove the protective cover by loosening the two hold-down screws.
IMPORTANT - SEPARATION BETWEEN INTRINSICALLY SAFE AND
NON-INTRINSICALLY SAFE WIRING MUST BE MAINTAINED.
6. Pull properly marked 2 to 3 conductor wiring (depending on sensor configuration) for each
sensor through the conduit leaving at least 24 inches excess at both console and junction box
ends for final connections. The field wires must be resistant to hydrocarbon liquids; type THHN
or MTW, 22 AWG is recommended.
7. Fill all conduit VAPOR SEAL-OFF FITTINGS with approved filling compound and tighten all
conduit fittings.
8. Splice all sensor wires to the respective conduit wires at each WATERTIGHT JUNCTION
BOX. (See Bulletins 179 and 180 for a recommended procedure). Maintain correct
color-coding between wires.
9. Connect sensor wires to the LC1000 INPUT TERMINALS following Figures 3-2 or 3-3. The
terminal blocks may be removed for ease of wiring by pressing with your finger down toward
the conduit openings. Note that for multiple channel consoles, power need only be wired to
the right-hand circuit board. Maintain correct polarity between wires and respective terminal
points.
10. Properly dress all wires inside the wiring sections and re-install the protective aluminum cover
over the terminals.
11. Sensors should be logically identified as to location and type and recorded on the Sensor map
provided in this manual, SECTION 3.3.
CAUTION
Sensor wires are to be connected ONLY to the designated input terminals of the
INTRINSIC SAFETY compartment. DO NOT allow sensor wires to cross over into
the non-intrinsically safe section. FAILURE TO COMPLY MAY RESULT IN
PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.
CAUTION
Relay output terminals are located on the NON-INTRINSICALLY SAFE side of the
console. ALL wiring to these terminals MUST enter through the designated
conduit opening. Refer to FIGURE 1-4. FAILURE TO COMPLY MAY RESULT IN
PERSONAL INJURY, PROPERTY LOSS AND EQUIPMENT DAMAGE.
