For standalone access control at an entrance to a property, or inside a building, CENTSYS offers the SMARTGUARDair wireless access control keypad which affordably delivers unmatched functionality and reliability. The SMARTGUARDair wireless keypad can accommodate up to 1 000 unique PIN codes with any user-defined length from one to ten digits. There are 15 separate channels, each able to be paired with any of the CENTSYS code-hopping receivers. Such functionality caters for many different scenarios for example: a motorised gate entrance may be opened fully using one code, or activate the pedestrian opening using another, and switching on the house alarm using a third. User codes can also be selectively deleted without affecting other codes stored in the memory. The keypad also boasts a “downcounter” allowing select codes to have a limited number of uses. This is ideal for granting single occasion access, for example to an armed response company with the code deleting itself after use. The same memory module used on the D10 industrial sliding gate motor, may also be used on the SMARTGUARDair, allowing all the settings and codes to be backed up and restored in seconds.
