Yes - Fire extinguishers should ALWAY be located between the likely source of fire and the door. Easiest way to do that is to have the extinguisher at/near the door/stairs out. The basement unit is mounted on the side of the staircase, the linen closet is next to the steps down from upstairs, the kitchen unit is next to one of the doors out, the garage unit is on the wall next to the door

Next year, there are plans to renovate my house (fingers crossed) - one item on the lis of a "would be nice - let's see the cost" is putting in a sprinkler system!
