Installation Instructions

Connecting
the Current Sensor(s)
Typically, the current sensor is used to measure
battery discharge current to allow battery testing and
utilization of the Battery Condition bar graph. In this
application, the short orange lead connects toward
the power supply and the long red lead connects
toward the battery. See Diagram 5 for wiring details.
If not using the current sensor for the battery, connect
the Current Sensor in-line with the device(s) to be
monitored. To read current in the correct polarity, the
positive current should flow from the longer (red) lead
to the shorter (orange) lead on the current sensor. If
current is being displayed in the opposite polarity than
expected, swap the short/orange and red/long leads.
After connecting the red and orange leads,
connect the white cable to the “C1” or “C2”
connector on the Securitron Netlink.
Connecting
the Event Input
Connect one end of the Event cable to the Event1
connector on the Securitron Netlink board and cut
off the connector at the other end of the Event cable.
Connect the red and black wires to the voltage to be
monitored. If monitoring a relay or switch contact
(a common example would be the tamper switch of the
enclosure), an external voltage must be run through the
contact. Set the Event1 Input Invert Jumper as required.
Example:
To monitor the NC tamper switch in a Securitron
enclosure, connect a positive voltage (from the
Securitron AQL power supply or distribution board)
to one lead of the tamper switch. Connect the other
lead of the tamper switch to the red (positive) lead
of the Event cable. Connect the black (negative) lead
of the Event cable to the negative (DC Common)
of the voltage source. (Diagram 6, next page)
Since we want to cause an alert on the removal of
voltage, leave the Event1 Input Invert Jumper OFF.
