Additionally, the E2S Hootronic alarm horn sounders faithfully replicates the sounds made by legacy electro-mechanical signalling devices.
FTEvacuation sirens are used in many applications to provide a warning or notification of approaching danger, for example: tsunami warning, civil defence, tornado alert, toxic leaks, flood warnings and in a range of other emergency situations.
Many countries, such as Australia have a national ’evacuate tone’; the UK however does not. The relevant standard, BS 5839-1, merely states that the evacuate tone should contain frequencies within the range 500Hz to 1000Hz. However, for particular applications, such as offshore use, specific tones are defined. Known as “/information/pfeer-ukooa-guidelines”>PFEER– Prevention of Fire, Explosion and Emergency Response – as a minimum, there must be provision for three types of alarm on the installation or platform:
1. ‘Prepare for evacuation’ is a continuous constant amplitude signal with varying frequency of 1200Hz to 500Hz over one-second then repeated.
This alarm is tone 9 in the E2S alarm sounders, you can listen to the tone here:

1200/500Hz @ 1Hz – DIN / PFEER P.T.A.P. |
2. ‘Toxic gas alarm’ is a constant 1000Hz tone reinforced where
necessary with a red beacon or strobe.
This alarm is tone 37 in the E2S alarm sounders, you can listen to the tone here:
