this is a CLM type 92729DP this on is mounted on a roof of the Keith Factory co. this one was installed in 1962 part of the NAWSS civil defence system well it was supposed to be part of the NAWSS civil defence system but it was the plan was abandoned because the siren was owned by Keith Factory co. they refuse to make it a NAWSS civil defence system so Keith Factory co. owned it! is was use as a factory emergency system and monthly test. it was deactivated temporarily in 1971 for power upgrade in better controls. it was reactive in 1972 it was inactive in 1990 it stay like that until the siren was reactive in jun 1 2010 and it stay like that ever since.
