House alarms

[Moonshine]

I am doing the electrical layouts for my house design, and i am now thinking about house alarms.

 

The alarm that i have in my current house is wired PIR sensors in each room, with magnetic switches on doors.

 

This is obviously old tech, but in modern alarms are wired PIR sensors still used? if so it would make sense to show them on the electrical plans as wiring them at first fix would be so much more easier than retrofitting.

 

Or has the world of house alarms moved on significantly?

I've stuck with the traditional version. KISS. also have one in a duct going out to garage. Set separately at nights.

Go with the cables if you can it will be worth while having to save change batteries etc, possible interference etc.

personally I think it’s better.

 

run 8 core to each point back to the control panel, remember to mark each cable at the control panel.

I use dual tech sensors combination of pir/microwave sensors where both sensors have to detect to activate a signal 

 

these are in one unit and require 1 cable
