Best places to put a smoke alarm in a shop?
This morning our Pie Warmer shorted and caught fire. We noticed a smell, then haze, then smoke. So we rung the fire brigade and they came and everything was sorted. Luckily it didn't happen during the night, but the two smoke alarms in the shop didn't go off. The batteries were working fine (still beeped when the test button was pushed), so where are some ideal spots? The roof is quite high, and there is a lot of stock on the walls.
