The Columbia Boat alarm Model 411 is built for use in a boat.  Our boat alarm is inexpensive, is simple and is easy to install. The alarm is started and stopped with a key-fob remote control having a range of about 200 feet. When the alarm is started, the LEDblinking-LED starts flashing.  The flashing LED informs the owner that the alarm is active and warns an intruder that this boat is protected with a boat alarm.  The goal is to stop an intruder before he boards your boat.  When an alarm sensor senses an intruder a loud siren sounds. (110 db)  Typical alarm sensors include our canvas snap sensor, a hatch/door sensor, our cable wrap sensor, a pressure mat sensor and a motion sensor.

Our boat alarms provide boat security from an intruder. Yes, but why buy a Columbia Boat Alarm? First, it is inexpensive and easy to install.   Plus, we build it specifically for use on a boat. For example the alarm is enclosed in a plastic NEMA 4X enclosure to protect it from splashing and hose-directed water.  This is likely to occur on a boat.  All wires exiting the alarm enclosure pass through cable glands to prevent water from entering around the wire.  These wires are  marine grade wire. (Read the NEMA Specifications for the 4X Enclosure.)   Installation instructions for the alarm are on this website.
The flashing LEDblinking-LED should be located so it is visible from outside the boat and near an alarm sticker, warning that this boat is protected with an alarm system. The intent is to cause a would-be intruder to look for an easier boat to burglarize. This is a good example of a perimeter protection device. Perimeter protection is intended to cause the intruder to leave before he boards your boat.

The Columbia Boat intrusion alarm cannot stop or prevent a burglary. However, a properly installed system when active will cause a loud siren to sound when any of the alarm sensors is tripped. The intent is to discourage a would-be intruder, who will probably leave as soon as the siren sounds. An adequately charged battery is essential for the operation of the alarm.
