LifeSafety Power NL4

Four Port Network Communication Interface for Remote Power Monitoring, Reporting and Control

The LifeSafety Power Network Link™ module is part of FlexPowers’s patented power management system for security and life safety applications.LifeSafety Power Network Link™ module is part of FlexPowers’s patented power management system for security and life safety applications.

NL4 is a four data port network module that communicates and controls power status over a local or wide area network. The NL4 provides four SPI ports for connection to FlexPower devices that enables monitoring and control of the power system. Typical data gathered and reported includes operational fault status, power supply output voltage, battery charging voltage, battery charging current, and fire alarm input status.

Automated reports may be generated on any detected fault condition, battery aging, fire alarm interface activation, and event activation, or on a time base for scheduled confirmation of proper operation. A time and date stamped log of the past 1000 events is kept as history in a buffer and may be accessed as a scheduled report, or immediately on an alert or occurrence. The buffer is updated once per hour with all parameters in normal range.

In addition to four SPI connections, the NL4 provides two current sensor inputs, a remote temperature sensor input, a volt meter input, and a contact monitor input. The current, voltage, and temperature sensors may be given upper and lower limits to trigger an alert if the measured value goes out of range. The contact monitor input may be programmed to respond to either a normally open or normally closed contact or voltage presence or loss. Two outputs are also provided for use in power cycling external equipment with RB relay modules or interfacing to the C4, C8, or M8 modules
