Our boat alarms provide boat security from an intruder. Why buy a Columbia Boat Alarm? It’s simple, 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.  All the wires exiting from the alarm control are  marine grade wire. (Read the NEMA Specifications for the 4X Enclosure.)  Scroll down this page for some suggestions on how to protect your boat with a Columbia Boat Alarm. You can install it yourself.

Have questions?  Call Francis at 406-249-0640 from 8:00AM to 5:00PM MST. Note:  Francis can accept your credit card. (Shopping cart is on the right side of this page.)

A cell phone alert can be added to the Columbia Boat Alarm to provide additional security for your boat.  The cell phone alert will send a text message when the alarm siren is triggered.

Installation of a Columbia Boat alarm is simple and most individuals will have no difficulty with the alarm installation. Installation instructions for the alarm are on this website.
The 12 volt DC alarm is activated and de-activated with either a switch or a key-fob remote. As soon as the alarm is active a red LEDblinking-LED starts flashing. The flashing LED informs the owner that the alarm is active.

This flashing LEDblinking-LED should be located where 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 when a would-be intruder leaves the area 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.
