Accepted Answer

How to pair? You have to open alarm box(not so easy because it's water proof) then remove all 3 batt. and after some time put them again. Before close alarm box check up pairing.

Question 3

Would this work for a powerchair? It doesn’t have any keys

Accepted Answer

IT will work on anything that moves even doors, windows etc, you can pop it in your pocket, arm it and if you move the alarm will go off :) you can fall asleep 
drunk & if anyone tries to rob your pockets it`ll wake you up :)

Question 4

Could I use this placed in a pocket in a rucksack in a tent at night?

Accepted Answer

As long as you don’t need to disturb the ruck sack ? I use it on an outside shed and as soon as some tries to open the door it sets a 1 second warning off then it rings if I persists with trying to get in,  it’s a great bit of kit that as a lot more uses than a bike , the arm and disarm beep is a touch loud But if it’s in your bag it would be fine
