Product details
Designed for powersports environments
Directed engineered the 3121V specifically for motorcycles, ATVs, boats, personal watercraft, and snowmobiles. The main module carries an IP66 water-resistance rating, and the kit includes a miniature water-resistant siren plus two compact waterproof 2-button remotes that are easy to carry on the water or trail.

Sensors, triggers, and anti-jacking protection
Onboard shock and tilt sensing help detect disturbance or movement. A closed-loop trigger can protect a helmet or other valuables—breaking the loop activates the alarm. An extra trigger input, auxiliary output, panic, valet mode, and anti-motorcycle-jacking features are documented in the Directed owner/install guide (500-10745).

What’s included and install notes
The kit includes the main module with wiring, two 2-button 1-way remotes (7121V), the water-resistant siren, and a combined install/owner’s guide. Professional installation is recommended.
