This is an add-on paging unit that can be added onto any of our PTS-2 trailer security systems. No additional antennas needed.
The unit is NOT water resistant, so it must be mounted inside the trailer. If you have a window, you will get better distance.
Connect this to the alarm system, and be notified if the alarm goes off, for free.
This unit does NOT have a manual paging button like our other system.
The distance on this unit depends on many things, but not limited to: type of walls of the trailer, where positioned in the trailer, any windows in the trailer, surrounding structures or trees, and more.
Simply connect one end to ground and the other to the siren output.
