Master Lock 4840DATSEN Trailer Sentry Boat Trailer Anti-Theft Alarm System provides a new way to secure a trailer to a vehicle by continuously monitoring the trailer's lighting circuit and triggers a remote alarm if the trailer is disconnected from the vehicle or if the wires are cut. It works alongside any mechanical security devices to offer a new level of security and convenience.

  • Provides electronic security through a 110 decibel alarm siren that sounds when the trailer wiring is cut or disconnected and acts as a power module to deliver needed power directly to the trailer from the vehicle battery
  • Alarm mounts under the hood and power module mounts under the vehicle with a voltage sensor to prevent battery run down and detects if a light is burned out
  • Revolutionary theft protection for your boat trailer is fully submersible
  • Trailer lights can be disconnected via the remote while trailer is submersed in water, features remote lighting cut-off
  • Includes 1 fob, simple installation
