What parts are required to fit a Sounder Beacon to my Lifeline 4000+, and is an engineer required?
A. A Lifeline unit, the Sounder Beacon and a 12v dc power supply (part number 8020/48) are required. The Beacon is available in red (part number 92100/18) or blue (part number 92100/20). Where the Sounder Beacon is used with scheme equipment a power supply is not required. The installation requires an electrical qualification with an understanding of Tunstall programming.
