Ivy Self-powered sounder/flasher for outdoor installation Ivy is easy to program and even easier to install, these units boast unmatched features and performance. The external heavy duty cover swings down on easy-to-free hinge projections (located on the both sides of the backplate) to provide a practical tool ledge. A metal inner-shroud protects all the components and reinforces the casing. New-generation Light-Emitting-Diode technology provides super-bright flasher signals and allows extra-low power consumption. The units also provide two status LEDs, positioned at the sides of the flasher. The sounder can be programmed to generate different audible signals, thus allowing users to identify different types of alarms and/or locate the place of alarm. The units offer many programmable parameters for maximum application flexibility, such as: Maximum alarm time, Input polarity, Flash frequency per minute, Trigger signal, etc. Two models are available: Standard and BUS. In the “Standard” model alarms are triggered by power cut or by the activation of the ancillary START input. The “BUS” model connects to the SmartLiving BUS and is supervised and managed by the control panel. This direct-connection approach greatly simplifies wiring and system programming. In addition, it consents to the activation of event-related signaling (different signals for different events) programmed through the control panel.
