Security Monitoring – Intermediate System

Overview

This intermediate system provides security information including three motion detectors and three door/hatch switches. The display (DSM250) monitors the switch indicator (SIM100) and whenever motion is detected or a door/hatch is opened then the display shows a red indicator, and the alarm buzzer (ALM100) is sounded to notify everyone onboard and to scare off intruders. If the power to the motion detectors is turned off or if the wires to the motion detectors or door switches are compromised, then the display shows a yellow indicator to let you know that there is a problem and a particular sensor isn’t working. The color scheme is configurable so you can pick a scheme that works best for you. The display can also signal the texting module (SMS100) to send out one or more text messages as a notification that someone is on the boat. A text message can also be sent if the GPS antenna (GPS200) indicates that the boat’s position has changed indicating theft or a broken mooring line.

The following table shows the products included within this example system plus a list of the information or data available for display.
