Installation and Operation
Introduction
Product Description
The Netlink NL2, NL4, and NLX modules are network appliances which may be used with LSP power systems to provide remote
monitoring and control of the power system and connected devices. The NLX provides eight ports and the NL4 provides four ports for
connection to LSP power supply boards and M8 managed output boards. The NL2 provides two ports for connection to LSP power
supply boards only.
The Netlink module monitors power supply system status over a local or wide area network and provides values such as output volt-
age, fault status, battery voltage, battery charging current, and temperature. In addition, automated battery tests may be run manually,
or scheduled to happen automatically. When used with an M8 managed output board (NLX and NL4 only), voltage and current for each
individual output is provided, and each output may be individually power cycled.
Automated alerts may be sent via email or SNMP on any detected fault condition, service due date approaching, battery condition,
or on a time basis for status updates on regular intervals. A time and date stamped log of the past 1000 events is kept and may be
viewed on demand, or immediately on an alert occurrence. When all parameters are in range, the log is updated once per selected
interval with a snapshot of current values.
All Netlink modules provide a voltmeter input, event input (for monitoring devices such as the enclosure tamper switch), and one, two,
or four current sensors. Internal temperature is also sensed, and the NL4 and NLX also include a 6 foot external temperature probe
for monitoring room temperature. The NL2 and NL4 provide two outputs for controlling external equipment using LifeSafety Power’s
RB series of relays. The NLX provides two form C relays on-board for external control.
If using the NetLink in an FPA AC voltage system, an NS2 module must be used to provide DC power to the NetLink and may also be
used to remotely switch the output power.
