Network Relay Controller

The Network Bell System consists of a Network Relay Controller, a Wired Ethernet Connection and Software. It allows for the turning on or off a bell, buzzer or horn at scheduled times. The system is very simple to install and easy to maintain.

The Network Relay Controller is equipped with two normally open contacts and two normally closed. The Network Relay Controller will be connected to your existing Ethernet.

The software should be installed on a PC that resides on the same network as the Network Relay Controller. Thereafter schedules may be input to the software programme to activate the controller and the bells or buzzers will sound at the exact time the event(s) is/are scheduled.

The Network Relay Controller can switch any electrical devices with a total current rating of up to 4.4 Amps. A horn or buzzer is a device that is commonly used in a manufacturing or warehouse environment to signal changes of events. These events can be scheduled for breaks or lunch. Whenever you need to signal the start or finish of an event with an audible sound this product works exceptionally well.

Innovation Wireless has a customer-oriented approach to our engineering. We strive to make our product user-friendly. Our bell system products are part of our family of synchronised clock systems and public address speaker systems.

You will produce the schedule of events or relay changes using the software. Once you create your schedule or schedules you would save them. The active schedule is then downloaded to the controller unit. Once the schedule is downloaded the network relay controller will operate independently of your PC until you initiate a schedule change.

The controller can operate with AC power or with PoE (Power over Ethernet). This enables you to easily place the unit at the most optimal location. Additional features include:

  • Control Multiple Bells or Buzzers
  • Group Multiple Controllers
  • Easy to Install
  • Maintenance Free
