Movement of the trailer will be detected by the built in accelerometer, or the opening of a door. This will cause the electrical brakes of the trailer to be applied in addition to the sounding of the 120db waterproof siren provided, and the flashing of your trailers running lights. Optional switches and motion detectors are available for professional installations. PRO-TEC System has been designed specially for easy installations. With the brake safety toggle switch, the trailer brakes won't accidentally lock up if the alarm is inadvertently armed. The system is housed in a custom 3D printed 10 x 7 x 2.5 inch enclosure.We have now mounted our basic PTS-2 alarm in the same enclosure as our G2 system, making it easier to upgrade if/when desired.The brake safety toggle switch is mounted inside the enclosure.Voltage Max: 15 VDCOperating Temp: 185°FCurrent (Armed): 7 mACurrent (With Optional LED): 19 mANote: Additional current may apply with optional equipment connected (Our systems use wired sensors.
