Two Inputs, Max Flexibility

Inovonics Universal Transmitters make normally open/normally closed (NO/NC) sensors wireless. Designed for maximum flexibility, the Dual Input Universal Transmitter includes two inputs for external contact loops and works with almost any standard contact or sensor. The transmitter can be fully supervised when registered with your security system.

  • Supports dual inputs
  • Can be used with almost any standard NO/NC contact
  • Fully supervised to help ensure reliability
  • Includes case tamper protection

How It Works

The transmitter has a three-terminal contact block that can connect inputs from one or two external contact loops. The middle terminal is a ground, which is shared by both contact loops. Input one can be configured for either a normally open or a normally closed contact loop using the NO/NC selection pins; input two is always normally closed. When supervised, the transmitter sends a check-in message to the receiver every three minutes.

For Use With:

  • Door contacts
  • Shock sensors
  • Holdup buttons
  • Pressure mats
  • Temperature sensors
  • Status relays
  • Photo-electric beams
  • Other binary output devices

NOTE: The EN1212 requires use of a serial receiver or network coordinator, as well as an application designed to support advanced functionality.

Inovonics Wireless: Developed For Commercial Applications

The Inovonics Commercial Mesh Network has been specifically developed for commercial applications to provide the most cost-effective solution for a wide range of applications, while setting new standards for performance and reliability in a wireless sensor network.

Reliability: Inovonics EchoStream 900MHz radio utilizes a unique frequency hopping, spread spectrum technology to meet the demands of an increasingly cluttered wireless world.

Flexibility: The flexibility of wireless is a necessity in today's dynamic commercial environments. The self-configuring EchoStream Commercial Mesh Network allows you to adapt to changing floor plans and requirements in a matter of minutes. New sensors can be added to the network as fast as they can be mounted.

Scalability: The EchoStream Commercial Mesh Network's backbone of intelligent repeaters can extend coverage to thousands of sensors across entire commercial campuses.
