Installation Instructions

Making the Power
Connections to the
Securitron Netlink
DC Systems ONLY
In a DC system, the DC power source for the
Securitron Netlink is connected to the INPUT
(V+ & V-) fastons. The voltage of this source
must be between 8 and 30 VDC and should be
backed up with a battery set or UPS to maintain
communication during a loss of primary AC voltage.
The power connections for the Securitron
Netlink must connect directly to the main or aux
output of the Securitron AQL power supply.
NOTE: Do not power the Securitron Netlink through another
accessory board’s output or from the B1/B2 connectors.
WARNING – Do not connect ac power to the
Securitron Netlink board’s input (v+ & v-) terminals
or damage to the Securitron Netlink will occur.
Making the Ethernet
Connection to the
Securitron Netlink
Plug the Ethernet cable into the RJ45 jack on the
Securitron Netlink until the locking tab clicks. Connect
the other end of the Ethernet cable to the network.
NOTE: The Securitron Netlink board should be configured
via a direct connection to a laptop or PC before
connecting to the network. See the Initial Configuration
Section (page 23) of this manual for more details.
Connecting Devices to
be Monitored to the
Securitron Netlink
Connect one end of the SPI cable to one of the “Device”
connectors on the Securitron Netlink. Connect the
other end to the DataLink (DL) connector of the device
to be monitored (such as an Securitron AQL – see
the manual for the device being connected for the
location of the DL connector). If monitoring more
than one device, repeat this process for devices 2
through 4 as appropriate. Note that both ends of these
cables are keyed and will only plug in one direction.
If monitoring the battery health of Securitron AQL
power supplies using the Current Sensors, the
Securitron Netlink will assign Current Sensor 1 to the
Securitron AQL power supply connected to Device 1.
Current Sensor 2 will be assigned to Device 2.
NOTE: NL4 can accommodate any combination
of a maximum of two power supply boards.
