The BRK 700RF series of radio-interlinked smoke and heat alarms are 230V mains powered units with a 10 year sealed lithium back-up battery. Each alarm is supplied complete with a mains powered radio-frequency base plate as standard, allowing up to 50 smoke and heat alarms to be wirelessly interlinked within a single system. Radio-interlinked alarms are ideal for use where interlinking cables would be unsuitable for the application.
