## Description

Product description Linortek`s Netbell-2-1Bel - a controller+bell kit - is a one-stop IoT solution for small schools or shops ( up to 6000-8000 sqf, depending on the noise), to build an automatic network break bell system for signaling class changes, shift rotations, lunch breaks and any other timed signal applications. The kit includes one Netbell-2 network enabled bell controller with bell scheduling firmware, accessible for NO additional charge, using any browser on any PC in your network, one signal bell (6 inch, 86dB@10 feet). The bell is attached to weatherproof back box for wall mounting and has a 12VDC power supply transformer. The bell has to be wired to the Netbell-2 controller with two-conductor wire - we supply 10 ft of 18 gauge wire with the kit, and you may choose to use longer wire extension, which you can get at any hardware store or online. The bell can be wired at up to 250 feet away from the controller if you use 18AWG wire, or up to 500 feet with 16AWG wire. The Netbell-2 network and POE enabled bell controller is built on a TCP/IP platform with a built-in web server and special software designed for scheduling your bell system. With the intuitive and easy to use web interface you can access, control and schedule bells over the network or via Internet, no additional software or designated PC are required. You can wire one or two push switches (not included in this kit) to ring bell manually in case of emergency. You can add up to 3 more bells to this system later, if you need better coverage. Bell kits for the Netbell contollers can be found in Linortek website store. We (Linortek) provide free tech support, please reach out to us if you need assistance. Safety Warning When wiring a line voltage device you MUST either be a qualified electrician or use the services of a qualified electrician. Additionally, local codes must be followed including but not limited to wire gauge size and suitable housing.

## Questions & Answers

**Q: Does this need to be wired to the internet to work on network or does it have built in wifi to connect?**
A: This unit does not have built-in Wifi, you will need to connect it to the network for initial setup (adding schedules), then you can remove it from the network and it will work as a standalone device. You only need the network when you need to make changes. Hope this answer helpful.Linortek

**Q: If power is lost, do I have to reset the time and schedules?**
A: No, you don't. There is a built-in rechargeable battery on the board that can keep the time & settings for up to one week.

**Q: Can you purchase multiple bells that work together and handled by one program?**
A: Yes, there are two relay outputs (10A each) on the controller, you can daisy-chained multiple bells to the controller as long as they are not over 10A. The other fact that you need to consider is the bell's power supply. The power supply comes with this kit is 1A, so you can wire one additional bell to the same relay output.

**Q: Does this have multiple tone options?**
A: No, this kit does NOT have multiple tone options. But you can set different ringing duration for different break time. For example, you can ring 5 seconds for morning break, and 10 seconds for lunch breaks, etc.
