It's also a pity that you are not a professional alarm installer, then you would know all the intricacies of the rules and regs issued by assorted bodies that we and manufacturers have to work.
I don't envy you. Most of the rules and regs are totally unnecessary boxticking brought on your industry by previous alarm companies cutting the corners and taking the money and running.
I had a job in an industry regulated to the Nth degree where even everything you ever said or decided was recorded to leave an audit trail for future litigation. Even with that level of control incompetence was everywhere along with dishonesty greed , laziness , avoidance of responsibility.
Rules don't intrinsically change behaviours or improve standards they just allow lawyers to earn money.
