Vitor Ferreira Posted April 7, 2020 Share Posted April 7, 2020 A self-powered audible device is equipped with an internal source of energy to power the bell. In the event of the main power failure, it can still activate via a secondary power source. In most bells, a backup battery is used. The modern bell boxes comply with the British standard BS50131 and use rechargeable Ni-Cd batteries which are kept charged by the control unit. A self-powered audible device needs to comply with Annex C of PD 6662: 2004 and with all the other provisions of prEN 50131-1: 2004 relevant to WDs. The code of practice (Sub-clause 8.1.4 of prEN 50131-1:2004) also emphasis that means shall be provided to recognise a fault condition in the alternative power source. 2 Link to comment https://www.thesecurityinstaller.co.uk/community/topic/40506-what-is-meant-by-the-term-self-powered-warning-device/#findComment-498253 Share on other sites More sharing options...
