[QUOTE="UNG, post: 499725, member: 8931"] The old Gents drop head heat detector fitted quite a few of them in times gone by and they were still being installed until the early 80's What you see is what you got the white cowl was an optional extra and a lot of the heads were fitted without it If you push the bimetallic strip up you can drop the detector down to reveal the mercury switch The 240v three wire alarm system was quite common and still in use in a lot of places until the mid 80's it's downside was no battery backup converted a lot of them with the drop front Gents panel that was popular in the 70's [/QUOTE]
