The EIB3024 is a Multi-Sensor alarm containing 2 separate sensing elements, intelligently monitored, in order to detect the presence of fire. Using its intelligent dual monitoring, it responds much faster to all fire types (TF1 to TF6 & TF8) than a traditional single sensor Alarm. In addition, the chamber design, integrated insect screen and unique dust compensation algorithm reduce the risk of false alarms. The EIB3024 is powered by 230V AC mains. In the event of mains failure, the rechargeable 10-year built-in non-removable lithium battery will provide up to 3 months power supply in the case of a wireless RF installation or up to 6 months in any other case. The AudioLINK feature facilitates acoustic download of the alarm parameters and status using the AudioLINK app. The EIB3024 can operate as a standalone alarm or can be interconnected either by hard-wire or wirelessly (using the EIB3000MRF module) enabling it to communicate with compatible Brooks alarms and accessories. Up to 12 devices can be interconnected. The EIB3024 self-checks its sensors, battery voltage and internal circuitry every 48 seconds. Any fault condition found will be indicated by a combination of yellow LED flashes and chirps. The memory feature allows an alarm that has previously activated to be easily identified (through the red flashing LED)
