Honeywell LCBS Connect Installation Instructions page 3

Wire the terminal block as shown in Fig. 5:
1. For single wires, strip 3/16 in. (5 mm); for multiple
wires going into one terminal, strip 1/2 in. (13 mm)
insulation from the conductor.
2. Insert the wire in the required terminal location and
tighten the screw to complete the termination.
3. Review and verify the terminal connection wiring
illustrated in Fig. 5.

4. See Fig. 6 for wiring multiple Sylk devices.

5. When wiring is complete, align the pins from the
front cover to the terminal block on the subbase.
6. Firmly push the front cover onto the subbase. If the
wall module is powered, a loading screen will be dis-
played.
Sylk Bus
The wall module communicates with the LCBS Connect
controller via Sylk, which is a two-wire, polarity-insensitive
bus that provides both 18 Vdc power and
communications. This enables a faster and cheaper
installation all while minimizing errors. The recommended
wire for Sylk is 18-24 AWG (0.82 to 0.20 sq mm) single
twisted pair, solid or stranded wire, unshielded for a
maximum distance from the controller of 200ft (60m).
Standard thermostat wire (non-twisted pair) can be used
for runs up to 100ft (30m). See Table 1.

The wall module is intended to always communicate using
Sylk address 1 and is shipped from the factory with this
address configured. Other Sylk sensors are compatible
with the LCBS Connect controller and wall module but
limitations must be observed. Up to FOUR additional Sylk
sensors can be used unless a TR40-H, TR40-CO2 or TR40-
H-CO2 is used. Then the allowed additional sensors drops
to THREE. See Table 2 for a listing of the compatible Sylk
sensors.
Compatibility
The LCBS wall module has been designed specifically for
the LCBS controller. They are a one-to-one pair and
adding an additional LCBS wall module will result in a loss
of operation. Connecting an LCBS wall module to another
Honeywell controller will also result in the loss of
operation for the wall module.
