Nautic Alert XPulse ™

For Yacht Security, Safety, Multi-Bank DC, and Shore Power Monitoring.


XPulse and XPulse Plus 1.0 120417


Nautic Alert XPulse and XPulse Plus is how security and safety sensors seamlessly integrate with the Nautic Alert Platform.  Multi-Bank DC monitoring and shore power detection is also expanded through one or two XPulse/XPulse Plus sensors.

Nautic Alert XPulse is a component of the Nautic Alert X2 Decision Platform serving as an intelligent interconnection point for XPulse smart embedded sensors and for “hardwired” boat security sensors, which communicates with Nautic Alert Insight X2 using a wireless interface. XPulse provides inputs for the following:

  • AC Shore Power XPulse Embedded Sensor with 1 Input
  • DC Battery Bank 1, XPulse Embedded Sensor for 6-37V with 1 Input
  • DC Battery Bank 2, XPulse Embedded Sensor for 6-37V with 1 Input
  • DC Battery Bank 3, XPulse Embedded Sensor for 6-37V with 1 Input
  • DC Battery Bank 4, XPulse Embedded Sensor for 6-37V with 1 Input
  • 4 “Hardwired” Security Sensors with 4 Dedicated Alarm Zone Inputs
  • 12V Regulated Output for powering Sensors
  • 12V Regulated Output for powering Insight
  • 12V Siren/Visual Output With Panel Mount 95db Built-In Siren

Block Diagram

XPulse/XPulse Plus is powered by up to 4 DC bank inputs (6-37V) and/or AC/DC power.  Each input power source provides power-path redundancy to XPulse.  So, in this scheme, one more more backup batteries can provide input power to XPulse.  XPulse regulates the incoming power sources to a 12V output that can be used to power Insight (optionally), security sensors, and the integrated or externally connected siren/LED indicator.  XPulse Plus powers the wireless security module, and cannot be used to additionally provide power to Insight.

Powering Insight from XPulse can be done if a redundant power security system is desired.  In this case, XPulse can support one or more dedicated backup battery banks to keep Insight and security sensors powered-on in the event of a total system power loss.

XPulse/XPulse Plus include a waterproof siren that can be enabled with the wireless siren sync setting on Insight.  Optionally, this siren can be easily disconnected if a customer-supplied 12V siren or visual wired indicator is preferred.  See Onboard Alarm Network section for additional details.

XPulse/XPulse Plus includes IP68 cable glands for all cabling entry/exit.  When sealed properly, XPulse and XPulse Plus provide full IP68 waterproofing.


Zone Types and Descriptions

The following describe the zone descriptions that can be assigned to each zone input on XPulse or XPulse Plus.  More than one N.O. sensor input can be wired into a single zone that shares a description or location as shown below.  If multiple N.O. sensors are wired into a single zone, it’s important to note that only one alarm event can be detected at a time for that zone.

    • Contact Sensor
    • Motion Sensor
    • Glass Break Sensor
    • Smoke Detector
    • Fumes Detector
    • Carbon Monoxide Detector
    • Radar Instruction Detector
    • Water (high-water float switch or equivalent)
    • Temperature
    • Zone
    • Personal Local (MOB on-board siren notify)
    • Personal Monitored (MOB GEOS SAR Monitored)

Battery Bank Interconnection

XPulse and XPulse Plus
4-Channel DC Input

4 individual battery banks support DC voltages from 6 Volts to 37 Volts.

With Nautic Alert Insight X2, each battery bank can be configured for AGM, lithium, or a custom battery type and nominal voltage. Custom alert and critical thresholds can be set for each battery bank. Additionally, a customizable DC filter prevents load transients from generating false alerts, and state transitions use hysteresis of about 100mV to prevent “flapping” conditions.
