The Node Controllers provides a communication interface to the Nemtek Tension wire sensors and any other third-party security systems. Two separate sensor input channels are provided – each capable of accommodating up to 31 tension sensors and can be easily configured and programmed.

There are two variations to the node controller. The Node 1 can communicate and interface to third-party security systems through an ethernet port (Nemlink) or with the Nemtek Smartcard on a network. The Node 2 can communicate and interface to the third-party security systems through the two relays provided.
