alarmzentraleModern security concepts in museums and exhibitions require intelligent systems that can be quickly adapted to changing requirements. The HDF-BUZZER radio control unit issues freely adjustable alarm notifications. Alarm modules can therefore be mapped to the individual alarm centres. The possibilities can range from a local alarm at the exhibit to an alarm for a room or building. Smaller museums, for example, can activate a short acoustic alarm at the checkout counter. Supporting different operating modes enables the use in large houses. The organisational and exhibition structures used in these venues can be mapped like for like with the Human Detector Flex security technology. Activation and deactivation of alarm groups - but also confirmation of alarms - can be actioned directly at the HDF-BUZZER unit. The wide radio range and the central layout of the radio control centres reduce costs in comparison with decentralised security systems. Supervising staff on duty is substantially supported and relieved.
