IET provides a range of controllers that can all stand alone.
Simplest of all is EasyCode – a keypad entry system able to control one door.
To control two doors using proximity or magnetic stripe readers the EasyAccess unit will fit the bill.
Also available is Innoprox Lock – an integrated proximity card reader and single door controller. Innoprox Lock is also designed to be expandable with RS485 and PC interface for programming and monitoring of up to 6 doors, whilst the unit can also be reconfigured to be used as a reader should you later wish to upgrade to a high security on line system.
IET also makes more capable controllers, and whilst they are most often networked the Tower and Integra controllers can both be run as stand-alone units. In those instances programming may be done either by using a TPROG hand held programmer or by connecting temporarily to a PC.
