The most compact sounder in the Asserta Range, the Asserta Mini Sounder/Beacon (S/B) is a rugged unit with a high IP rating. Suitable for use in harsh environments, its low current consumption and optional integrated beacon adapt it well to either fire systems or use as a general signalling device in industrial applications. Where the Mini is used in secure applications there is an option to add a tamper switch so that any interference with the unit can signal an alarm to a security panel.
