Air Raid Sirens

From Historical Hastings Wiki

Summary[edit]

Hastings had a number of sirens to give warning of the approach of enemy aircraft during and following WW2. These were either mounted at the top of a wooden pole with a control box adjacent, or on the roof of a nearby property, drawing electrical power or steam from the supplies available locally.[1] A campaign to raise funds to purchase the siren that stood at the top of Briars Avenue is underway in 2020.

The sirens made a very loud and long signal or warning sound. For an alert, the siren sound pitch rose and fell alternately, whereas the “All Clear” was a continuous sound from the siren.[2]In the case of the 'steam whistles', an attack was signalled by the whistles sounding intermittently for two minutes, whereas the 'All Clear' was a continuous note for the same duration.

Design and Manufacture[edit]

There were two main designs of electrically operated sirens in use in England, requiring either a three-phase or single-phase electrical supply. Gent was a siren manufacturer in Leicester, with Carter, a competitor, in Nelson, Lancashire. Originally it was only Gent that got the Government approval for providing sirens in WW2 due to a misunderstanding when tests were carried out. A Complaint[3] was raised in Parliament due to the number of persons out of work in Nelson and following a retest with a similar sized siren, both Gent and Carter gained Government approval as siren suppliers. Although both worked on the same principal, there were subtle design differences and the Carter design was believed to be superior. Certainly other siren manufacturers since have followed the Carter design which relates to the shape of the rotors.[4]

Siren Installations[edit]

An initial eighteen sirens were installed pre-war. Testing and upgrades led to finally nineteen, fixed sirens located centrally to locations where concentrations of population and employments were by 1939. The fixed sirens were supplemented by a further nine 'Auxiliary' sirens, together with steam whistles and rattles (used to signify a gas attack).[5]The Hastings & St Leonards Observer lists sites as the following; Glyne Gap Gasworks; Marina Fire Station; West Marina Railway Station; Shepherd Street Fire Station; Bohemia Police Station; Tramway Depot; Jnc of Briars Avenue and Sedlescombe Road North; Hollington Police Station; Hollington Laundry, Battle Road; Albany Hotel, Hastings; Hastings Railway Station; Watneys Brewery Stores, Bourne Street; Broomgrove Power Station; Halton Fire Station; Bradfords Laundry, Bexhill Road; Freelands Garage, The Green, St. Leonards; Buckshole Pumping Station, Alexandra Park; The Ridge Laundry; The Harold Road Laundry.[6] Many of the sites (such as laundries and fire/power stations) had steam generating equipment suitable for steam whistles, the other sites having electric sirens installed.The steam powered siren mounted on the Broomgrove Power Station was tested in isolation on the 25th July 1939 and was found to have been audible as far away as The Ridge, Middle Street and Hollington[7], although this was reported to have failed on its initial test a week earlier, a 'great cloud of steam' being reported as issuing from it.[8]

Cuckoo Warning[edit]

From 1942 onwards, certain towns on or near the South and East coasts that were liable to “Hit and Run” raids were permitted to sound a local "Alarm" signal publicly in addition to the national “Alert” warning. This was due to the fact that "Hit and Run" raiders often arrived over their target before the regional ACTION WARNING was received, but local spotters etc could pick up the enemy aircraft allowing the "Alarm" to be sounded quicker. The system adopted was known as the "Cuckoo" warning. By means of an attachment to a siren, a warning sound of alternating high and low notes could be produced i.e. "cuck" and "oo".[9] This system was known to exist in Hastings, but there were a number of criticisms that the difference between warnings and 'all clear' could easily be confused.[10]

Cold War Usage[edit]

Fourteen of the sirens continued in usage post WW2 as early warning sirens for potential attacks as the threats faced during the Cold War grew. A number of tests were held periodically between certainly 1954 and 1958[11].In 1954, the Hastings & St Leonards Observer reported; "The preliminary test of the air raid warning system which took place recently was not entirely satisfactory, as sirens In Blackman Avenue (near Dymond Road), Mount Road and St Saviour's Road were not in operation: further tests will be undertaken in due course, of which notice will be given." [12]

The sirens saw another resurgence during 1960/1970, being used to summon the reserve firemen to their local stations in the event of a callout. One was certainly known to have existed on the Priory Road Fire Station, with another possibly on the Battle Road Fire Station[14]

Current Day[edit]

No complete installations are known to exist locally, most sites being cleared soon after decommissioning. The last site to be cleared was that at the junction of Briars Avenue and Sedlescombe Road North which was removed during 2018.
