KT-MOD-INP16
KT-400 Expansion Module 16-Zone Input with SPI Cable Install Sheet
1.
Introduction
The
KT-MOD-INP16
is an input module that adds up to 16 zones
to the
KT-400
controller. The module supports daisy chaining;
you can interconnect up to 15 KT-MOD-INP16 modules for a total
of 240 external inputs per KT-400. Adding the 16 onboard inputs
of the KT-400 gives a total of 256 inputs per KT-400. Combining
input and output expansion modules gives the flexibility to
connect up to 256 inputs and 256 outputs.
Note 1
: The KT-400 SPI port maximum current draw, when the
12V AUX terminals are not used, is 500 mA.
Note 2
: External power supply (12 VDC, 2 Amps) is required
when the total current draw exceeds 500mA on the SPI Port.

Installing the KT-MOD-INP16 Module
3.1. Unpacking
The
KT-MOD-INP16
package includes the following parts:
One (1) KT-MOD-INP16 module, 14 cm x 8 cm (5.7 in x 3.25
in)
One (1) SPI cable with 1 SPI connector, 41 cm (16 in)
16x 5.6K Ohms ½ Watt Resistor
Four (4) plastic standoffs
Two (2) installation sheets, English and French
3.2. Mounting
The
KT-MOD-INP16
can be installed inside a compatible cabinet
(KT-MOD-CAB or KT-400) or mounted in a dry and secure
location at less than 1 m (3 ft) from the KT-400.
1.
Press the four (4) plastic standoffs through the mounting
holes of the cabinet,
2.
Secure the cabinet to the wall in the desired location. Use
appropriate wall anchors when securing the cabinet to
drywall, plaster, concrete, brick or other surfaces.
3.
Press the module into the plastic standoffs to secure the
module to the cabinet.
3.3. SPI Wiring
Perform the following steps to complete wiring:
Note 1
: Before beginning to wire the unit, ensure that all power
(AC transformer and battery) is disconnected from the KT-400.
Note 2
:
If you are combining input and output modules through
the SPI EXP expansion port of the KT-MOD-INP16, the input
module must be the 1
st
module connected to the KT-400 SPI
Port.
1.
Connect the 6-pin SPI connector to the KT-400 SPI port or to
the SPI OUT of the previous KT-MOD-INP16 module.
2.
Connect the six SPI wires (blue (BLU), white (WHT), green
(GRN), yellow (YEL), black (BLK) and red (RED)) to the SPI
IN (TB1) terminals.
3.
You can use the SPI EXP of the 1
st
KT-MOD-INP16 to start a
group of output modules (
KT-MOD-REL8
and
KT-MOD-
OUT16 only
).
4.
Connect the 6-pin SPI connector from the SPI OUT to the
next KT-MOD-INP16 module.
5.
Complete all zone wiring to the zone input terminals (Z1-Z16).
