Human Detector Flex - Alarm module for securing pictures on gallery rails
The HDF-HANG wireless alarm module is simply mounted near the gallery rail. It is attached to the wall or hung directly in the gallery rail with an optional holding plate. The brass latch on the HDF-HANG alarm module is connected via a short tension spring to one of the two holding ropes hanging from the gallery rail. The position of the bolt is monitored via a magnetic switch in the sensor electronics. If the picture is taken down, the weight on the holding rope will change and an alarm is immediately acitvated. The system is maintenance-free and has a long battery life of 10 years. The integrated 868 MHz transmitter module achieves a high range even in solid buildings such as castles and palaces.
The Human Detector Flex sensor HDF-HANG can be combined with all alarm and voice output devices (such as HDF-BUZZER and HDF-SPEECH) and the alarm monitoring unit HDF-AMD.
