HDF-AMD  Alarm-Management-Device







The HDF-AMD automatically monitors all activities and alarms in your museum. Alarm messages are routed directly to internal or external control centres or receivers. The professional solution avoids the exhibition being disturbed by alarm sounds, if desired. The HDF-AMD system is a forward-looking and innovative form of alarm monitoring and processing.

alarmzentraleDue to its various alarm control units and sensor modules the Human Detector Flex alarm system is the ideal basis for effectively securing and guarding exhibitions, collections and luxury goods. Operators quite often do not wish to disturb visitors of the exhibition with acoustic alarms from the alarm system. Private collectors may wish to have alarm messages sent to external control centres or guard services. Video control centres were therefore installed in large museums for example with specially trained staff. The alarm centres control the room supervisors by radio and direct them to the exact location where the alarm was triggered. The HDF-AMD radio system can take over the task largely independently. The so-called alarm management unit evaluates all alarm messages and forwards them to the various destinations via SIA-DC09 CID protocol.There is no need for the usual siren sounds and voice messages, if required. The HDF-AMD offers various additional functions for comprehensive alarm management.

Convenience, increased security and cost reduction through alarm management

The Human Detector Flex system offers the possibility to expand your security technology with a modern alarm management system. This extension can be set up retrospectively for all existing installations, regardless of whether they are operated in EASY- or MULTI-Mode. The HDF-AMD unit is installed on your premises for this purpose. The compact device comprise three antennas and thus reliably receives all radio communication from the alarm sensors and radio control centres used. Several HDF-AMD can be combined with each other. hdf amd arrowThe initial installation of the HDF-AMD is easy and straightforward with the Configurator software. The installation enables the operator to use various new functions. These demonstrate the great flexibility of the security system and offer applications that are otherwise only known from larger control centres. This operating mode is called PROFI-Mode, to distinguish the gained functionality between EASY- and MULTI-Mode. 


Alarm-by-Silence - Exhibitions without interfering noise

There is a fine line when using security technology in museums where warning alarm sounds tend to disrupt an exhibition. Without doubt alarm sounds must be loud and act as a deterrent. But, if it occurs more frequently, it will be perceived to be a nuisance. With the Human Detector Flex technology there is no more need for disruptive alarm sounds at the protected object. On the other hand, it is possible to issue short warning tones or voice messages at selectable locations in the exhibition. This reduces disturbances of exhibitions by alarm messages to a minimum or to zero.


Increased safety through detection of jammers

hdf antijamIt is possible, in principle, to connect the radio alarm control panels (HDF-BUZZER and HDF-SPEECH) by cable to external systems such as burglar alarm systems. The use of wireless radio technology offers several advantages in terms of installation and the wiring work which is no longer necessary as a result. The transmission signal used by the Human Detector Flex enables a secure connection over longer distances. To reduce the risk of jamming, an additional protective measure can be activated in PROFI-Mode. The optional anti-jamming unit HDF-ANTIJAM is used for this purpose. The pilot transmitter sends a control signal that is monitored by the HDF-AMD alarm management system. Manipulation and interference is thus detected.
