What is the threat with remotes?

FIXED coded remote systems – particularly those using dip switches to set the code, are very easy to copy or clone. They also offer a very limited number of possible codes. In other words, these systems only provide convenience, with very limited security.

Main features:

  • 433Mhz operating frequency
  • Transmitters with one to four buttons
  • Transmitter quick and easy to open for battery replacement
  • Belt or visor clip supplied as standard
  • Transmitter body clip doubles as wall bracket
  • Self-learning receivers with one, two and four channels
  • Receivers incorporate stable narrow band technology
  • Weatherproof housing for receiver

The SupaNOVA is a versatile receiver compatible with the NOVA rolling code (KeeloqTM) range of remote controls. It is the perfect tool for multi-user applications such as access points to housing estates, offices parks and industrial complexes by allowing quick and easy management of the remotes operating the system.

This receiver allows up to 1000 separate remote buttons to be learned in to the system. Maintaining a clean data base of memorised remote controls is easy with SupaNova’s ability to selectively delete individual buttons or complete remotes.

SupaNOVA even allows mapping of any button on a transmitter, to any of the three channels that come standard with the receiver. This caters for those of us who want our own specific sequence of buttons to, for example, first open the gate, then the garage door and then the alarm system.

The convenient memory module can be used to backup and restore large sites in seconds ensuring that your data is safe and maintaining your data base is easy.

Main features:

  • Selectively add and delete users
  • Self-learning of transmitters
  • 1000 user groups available
  • Three channel output for greater functionality
  • Programming module separate from receiver
  • Mount console in secure and convenient location
  • Mount receiver in elevated position for optimum range
