The plan may be misleading - there is no partition between the Playroom
and Lounge room, only a couple of steps.

The motion sensors I had in mind were combined PIR/microwave sensors.

That is what I was going to recommend.

We mainly use the Equinox PI from Pyronix (This is a Pet friendly version of
the Equinox 10)

Others in the range are
Equinox 10 (10 Metre Range)
Equinox 15 (15 Metre Range)
Equinox E (15 Metre Range with look down zone) (not recommended near your
radiators)

If I put magnetic contacts on each door and vibration sensors on each
window, could I do away with PIR motion sensors all together? What
would be the disadvantages of this?

I have lots of radiators AND some underfloor heating so PIRs could be
more trouble than their worth.

The Main problem with perimeter ONLY security,

If ONE sensor fails then there is total access to the property.

You should be OK with dual-tec sensors, just make sure that the Microwave is
not turned up so high that it looks THROUGH glass.

Also if you are installing microwave sensors close to one another make sure
that they are operating on different microwave frequencies (Pyronix supply
3 different frequencies) Easily distinguishable by different colout
frequency stickers on the boxes - RED, PINK & GREEN.

Good point

How far away from radiators should dual-tech sensors be located?
