HELIH® Security radio window handle

HELIH® Security radio window handle
Innovation

The HELIH® is a handle for windows and French windows that combines comprehensive condition monitoring with electromechanical locking of the window/window door. It is suitable for both side hung and tilt and turn windows.

The HELIH® can detect the following states and send them encrypted by radio to the radio gateway:
- Handle position (down, sideways, up, intermediate positions)
- Window tilt position
- Window opening (magnetic contact, independent of the window tilt position)
- Sabotage of the magnetic contact (in case of excessively strong magnetic field)
- External field influence on the magnetic contact
- Lifting off the battery compartment cover or unscrewing the HELIH® from the window
- Enclosing the HELIH
- Handle locking (is the window locked by the HELIH® or not)
- Condition of the battery 
- General malfunction
- Optional: glass breakage and sabotage of the glass breakage sensor

HISAC® - RFID reader with touch function

HISAC® - RFID reader with touch function

Product description:

HISAC® stands for "Highly Innovative Smart Access Control". The HISAC® RFID reader (Radio Frequency Identification reader) with touch function is intended for use as an access control unit and as an electronic push button and door opener.

HISAC® stands out due to its compact design and easy installation. This means that a simple drill hole into which HISAC® can be inserted is sufficient. No screw connection is required to mount HISAC® safely and sealed.

HISAC® works with 125 KHz Hitag2 cards or tags, and 13.56 MHz Mifare Desfire cards or tags. Optionally, AES encryption can be applied to Mifare Desfire cards.

Furthermore, HISAC® has a touch function, i.e. when the glass surface of the front is touched, an electrically isolated contact closes for the duration of the touch.

An acoustic detector and an RGB LED are available as feedback elements for RFID detection and the touch function.

Communication with the higher-level evaluation unit is optionally possible via a CAN or Wiegand interface.

Product features:

  • Power supply 12 V or 24 V
  • RFID frequencies: 125 KHz and 13.56 MHz
  • RFID reading distance: ≤ 40mm, depending on the installation situation and the RFID frequency used
  • Encryption possible
  • Touch function with galvanically isolated output
  • Choice of CAN or Wiegand protocol
  • Compact design
  • Simple mounting
  • High protection class and seawater resistance when mounted
  • Cable length 7 m
  • Cable flame-retardant, seawater-resistant, recyclable, LABS-free, RoHs-compliant, acid- and alkali-resistant, ozone-resistant, UV-resistant, hydrolysis-resistant, drag chain-resistant, torsion-resistant, welding-spark-resistant, halogen-free, silicone-free, oil-resistant

Bolt Switching Contact RK-Lever

Bolt Switching Contact RK-Lever

With the universally applicable bolt switching contact RK-Lever you are able to monitor doors in an easy way. The Bolt Switching Contact RK-Lever is mounted securely behind the striking plate. The lever extension can be shortened in a flexible way so it can be used for most door bolts. There are small cutting points incorporated into the lever that make the contact easy to adjust. The switching point can be changed (up to 18 mm) with a slotted screwdriver after the contact is mounted. The contact is available with a cable or solder connection.

Locking Device VetraLock

Locking Device VetraLock

VetraLock 10-100 is a rubust electromechanical locking device. With the adjustable bolt position, it satisfies the high security requirements of the vehicle and transport industry.
VetraLock 10-100 guarantees reliable and robust locking. It provides low maintenance and has an emergency opening function. The device is used in vehicles, containers and trailers. VetraLock 10-100 offers a stainless steel bolt with a diameter of 10 mm and a potential bolt length of 100 mm. It can be applied where high security standards need to be fulfilled. By using a hall encoder, the locking distance can be adjusted from 0 up to 100 mm as desired. Therefore, existing installation requirements can be met easily. High resistance against mechanical loads through an aluminium housing and a solid method of construction are further positive features of the device.

Blocking Device EasyBlocker12

Blocking Device EasyBlocker12

Unintended entrance to secured areas can be avoided with the electromechanical Locking Device EasyBlocker12. Magnetic switches give feedback about the switching state at all times. There is no need to have a separate controlling unit installed, therefore the device is usable with almost any existing system.

Blocking Device Easy Lock

Blocking Device Easy Lock

The EasyLock is universally applicable and easy to install. It is characterized by its small dimensions. The locking in conjunction with the electronic evaluation (controller) is combined in a single housing.

The completely open concept allows an easy integration into almost any commercially available intrusion detection systems, access control systems and building management systems. Integrated feedback contacts give information about the switching status of the locking element. In addition to a high level of system integration, special emphasis was placed on the possibility of opening the device in case of an emergency and easy replacement of the locking bolt without disassembly.

BSS Security Seal

BSS Security Seal

The security seals are applied in the area of key management as well as in the areas of transport and logistics. The security seal secures goods, freight and other properties against unauthorised access. The seal is equipped with a unique identification number. The seal mechanism is protected within the plastic housing, therefore no access or manipulation is possible. The security seal cannot be opened after closing. Only destruction of the product allows to open the seal again. The sealing itself can be easily performed by pressing the ring into the plastic housing.
