Product details

The Nemtek Tension Sensor node controller 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 tesnion sensors.

The Tension Sensor node controller can be easily configured and programmed. This can be done by using the on-board OLED display, push buttons and jumpers Description provided. Alternatively, the configuration software tools can be used to configure the Tension sensor node controller and also programme the individual sensor sensitivities.

There are two variations to the node controller. The TW Node1 (E-TW/NODE1) can communicate and interface to third-party security systems through an ethernet port (Nemlink) on a network.

The second variety of TW node controller, the TW Node2 (E-TW/NODE2) can communicate and interface to the third-party security systems through the two relays provided.
