KT-MOD-INP16
KT-400 Expansion Module 16-Zone Input with SPI Cable Install Sheet
3.4. Check the power jumper JP5 position. Put it on EXT if you
need external power or INT if no external power is required.
Note
: In double end-of-line resistor configuration (JP4 ON position),
only 8 zone inputs (Z1 through Z8) are operational. Z9 through Z16
are operational only in single and no end-of-line configurations (JP4
OFF position). This configuration is available from firmware version
1.03 and later.
Interconnection is still limited to 15 KT-MOD-INP16 modules for a total
of 120 external double end-of-line inputs per KT-400.

Configurations with Jumpers
There are 4 jumpers available to configure the KT-MOD-INP16.
The jumper settings apply to
ALL
inputs at the same time.
DRY (no end-of-line resistor):
In a simple NC dry contact
configuration, the
secure
state is given when a short is detected.
The voltage becomes lower than the
Level 1
threshold value
(1.1V).
The
alarm
state is given when the input is open. The voltage
becomes higher than the
Level 2
threshold value (3.75V). If the
alarm switch is programmed as NO device, the
alarm
state will
be given when the input is shorted.
EOL (single end-of-line resistor):
For NC device, the
secure
state is given when a single resistor is detected. The voltage
becomes lower than the
Level 3
threshold value (2.9V) and
higher than the
Level 2
threshold value (2.25V).
The
alarm
state is given when the input is open or short. The
voltage becomes higher than the
Level 4
threshold value (3.75V)
or lowers than the
Level 1
threshold value (1.1V). If the alarm
switch is programmed as NO device, the
alarm
state will be given
when a single resistor is detected.
DEOL (double end-of-line resistor):
Both Alarm and Tamper
switches always operate as NC devices. The
secure
state is
given when a single resistor is detected. Corresponding digital
reading is lower than the
Level 3
threshold value (2.9V) and
higher than the
Level 2
threshold value (2.25V). The
alarm
state
is given when double resistors in series are detected.
Corresponding digital reading is lower than the
Level 4
threshold
value (3.75V) and higher than the
Level 3
threshold value (2.9V).
The
trouble
state is given when the input is shorted.
Corresponding digital reading is lower than the
Level 1
threshold
value (1.1V). The
tamper
state is given when the input is left
open. Corresponding digital reading is higher than the
Level 4
threshold value (3.75V).
Double End-of-Line resistor functionality not evaluated by
Underwriters Laboratories.
5.
Applying Power
After all wiring is completed, connect the 16 VAC to the KT-400.
Connect the battery leads to the battery, and then apply power to
the AC transformer.
Note
: Do not connect power until all wiring is complete.
This module provides access point control (5) as per EN50133-1.
Certified by Telefication under the requirements of EN50133-1 and
EN50130-5 Class II.
