Will a lamp on a timer switch coming on in a room with a pir in set off the alarm when it's armed?.

er, no

Er why not ?,my understanding is pir is passive and is triggered by sudden heat changes hence they tell you not to site them pointing towards windows or in drafts or do they need heat and movement.

for what's its worth I have some Philips Hue bulbs in my house, all 7 of them automatically come on just before dusk in different rooms (where there are PIR's) when I'm on holiday and have never triggered the alarm, although they are LED lamps and run reasonably cool.

You no the way it is on most Internet forums ask for a review of anything and 50%will say it's s hite and the other 50%will say it's the greatest thing since sliced bread.
On here you can usually get a reasonable explanation if you want some technical advice and not a brief reply /guess with attitude .

A cheap no name pir from the 1980s may be set off by the lamp, but modern quality branded pirs don't
