The Vertically Mounting External Sounder features perfect for protecting premises that require maximum security whilst optimizing value. The captive screw fixing method when combined with a tamper switch, provides the earliest possible indication of unauthorised access to the unit. The fully adjustable wall and lid tamper switch provides maximum flexibility to each installation. The low current mode is jumper selectable, as with SCB mode it enables a reduction in current drawn from the control panel, to allow installation of additional external sounders. Low current mode maintains significant sounder volume. The advanced electronic module of the Premier Elite Odyssey 1 is protected by a robust inner cover assembly with gasket seal. This maximises protection from dust and moisture, sealing to IP65 rating which enables prolonged exposure to harsher environments without compromising performance or functionality.
