Voltage Buss Connectors
These fastons are for connection to the B1, B2, and BR bus-
ses in the system.
B1 buss comes from the first power supply. This volt-
age will be directed to any outputs whose Buss Selection
Jumper is set in the B1 position.
B2 buss comes from a second power supply or a B100
secondary supply in dual voltage systems. This voltage will be
directed to any outputs whose Buss Selection Jumper is set
in the B2 position. If the SD4 is being used in a single voltage
system, these fastons are left unused.
BR acts as the Buss Return or negative connection to the
power supply(s).
2
Buss Selection Yellow Jumpers (1-4)
The SD4 can accept up to two power inputs connected to B1
and B2. These jumpers select which power supply input is
used for the outputs. If a single power supply is used, set this
jumper for Position 1.
B1 This position selects the power supply connected to B1
B2 This position selects the power supply connected to B2
3
Output Fuses or PTCs
These fuses or PTCs protect the outputs in the event of an
output overcurrent. Replace fuses only with the same type and
rating (ATM style, 3A). SD4P boards use nonreplacable PTCs
to provide Class 2 power limiting.
4
Zone Outputs 1-4
These are the output terminals. These terminal strips are
removable and accept wire sizes from AWG12 – AWG22. The
terminals are labeled on the PC board near the terminal strip.
5
Status LEDs (1 – 4) – Green/Blue
The Output Status LEDs indicate the status of the outputs.
LED numbers correspond with the zone number (e.g. LED 1
for Output 1).
• On SteadyOutput Powered
• SLOW Flashing (1 per second)Output Unpowered (Due
to FAI)
• FAST Flashing (4 per second) Fault Detected on Zone
• OFFOutput disabled in software
These LEDs are bi-color and indicate the output voltage for
each output as follows:
• Green – 12V Output
• Blue – 24V Output
I
NOTE LED colors are range based. Voltage Less than 13V
will show Green. Voltage above 20V will show Blue. Voltage
between 13 and 20 may show either voltage or a combination
Green & Blue. Always verify voltage with a voltmeter.
6
Fault LED - Yellow
T he yellow Fault LED lights when the SD4 detects a fault condi-
tion (including a tripped upper or lower limit - See the program-
ming section for more information). This fault condition also
transmits to the power supply through the FlexIO.
7RS485 Connections
These terminals provide the RS485 connection use with an NLX network
board. See the NLX manual for connection information.
8
FlexIO Connectors
These connectors pass the FAI and Fault signals to and
from the SD4 board and pass the FlexIO buss on to other
accessory boards in the system.
9
SPI Connector (J13)
This connector accepts the SPI cable which provides com-
munication between the SD4 and a local Netlink board.
Either this cable or an RS485 connection (#9) MUST be
connected at all times for proper operation of the SD4. The
SD4 must be connected to an NL4 or NLX board and will
not function if connected to an NL2 board.
bk
RS485 Addressing Switches
These switches set the address of the SD4 when using RS485 for
communication with the NLX network board. See the NLX manual
for connection information.
bl
Event and Temperature/Humidity Sensor Inputs
This terminal strip provides connections for the Event and
Sensor inputs.
Event Input
The Event input accepts a voltage input to notify the system
on an event change. Commonly used to monitor the enclo-
sure tamper switch. Not permitted to connect cables greater
than 98.5 ft (30 m) long.
Sensor Input
The SD4 temperature/humidity sensor connects to the Sen-
sor input. This sensor may be used to monitor the environ-
mental conditions of the room housing the enclosure. Not
evaluated by UL.

select whether fault conditions on each zone will send an email
alert when email is configured in the NetLink. Choices are "Yes"
and "No".
Voltage Lower Limit (V) - This column allows setting a lower
voltage limit to trigger a fault for each zone. For example, if the
lower voltage limit is set for 23.5V, a fault will be triggered if
the voltage on that zone goes below 23.5V. This limit will not
be triggered when the zone is deactivated via the zone's input,
FAI, or other intended deactivation.
Voltage Upper Limit (V) - This column allows setting an upper
voltage limit to trigger a fault for each zone. For example, if the up-
per voltage limit is set for 26.0V, a fault will be triggered if the volt-
age on that zone goes above 26.0V.
Current Lower Limit (A) - This column allows setting a lower
current limit to trigger a fault for each zone. For example, if the
lower current limit is set for 0.25A, a fault will be triggered if
the current on that zone falls below 0.25A. This limit will not
be triggered when the zone is deactivated via the zone's input,
FAI, or other intended deactivation.
Current Upper Limit (A) - This column allows setting an upper
current limit to trigger a fault for each zone. For example, if the up-
per current limit is set for 0.75A, a fault will be triggered when the
current on that zone goes above 0.75A.
Cycle Count Limit - This column allows setting a limit to trigger
a fault when the zone is activated a certain number of total cycles.
Output Limit Setting Aid - This section allows automatic setting
of the upper and lower voltage and current limits for each output.
To utilize the automatic settings, all output field wiring must be
completed to the output devices to be powered. Enter the desired
percentage for each limit, and click the "Start Measurement" button.
The SD4 will briefly cycle each output on and off and measure the
voltage and current levels for each device. When complete, the up-
per and lower limits will be set based on the entered percentages.
