Neutron Introduction

Neutron Introduction

1.0 Introduction

Neutron is a single-door controller which is configured and managed using Keri's Visual Doors software. It is a small, low-cost, easy to install controller that supports 1 or 2 NXT readers (1 x entry and 1 x exit reader) and is scalable up to 8 controllers per Appliance/PC via an RS-485 connection between controllers.

As well as NXT credentials, the controller also supports many HID 125 KHz credentials.


2.0 Main Features

Neutron ® has been designed with low cost and small physical size in mind, yet maintains a powerful feature set, nearly equal to Keri's NXT controllers. Works exclusively with Keri's Visual Doors Software.

  • Networkable via RS-485 for up to 8 controllers
  • Capable of In/Out access using Keri's NXT-E readers in conjunction with a standard NXT reader
  • 1000 credential capacity
  • Programable Lock Time
  • Auto Unlock by time of day
  • 4000 Event Buffer (offline)
  • Same small footprint as Keri's Intelliprox BlueTM and sharing the same enclosure

Up to 8 Neutron controllers can be networked together to provide a small system, with the
option of "In" and "Out" readers.

  1. Economical mini controller for a single door address.
  2. Works exclusively with Keri’s Visual Doors Software.
  3. Networkable via RS-485 for up to 8 controllers.
  4. Supports Keri NXT and NXT-E readers.
  5. Capable of In/Out access using Keri’s NXT-E readers in conjunction with a standard NXT reader.
  6. 1000 credential capacity.
  7. Event buffer 4000 (offline).
  8. Equipped with dedicated inputs for REX & Door Sense.
  9. Form “C” Relay for door control.
  10. Configurable for: Lock Time, Auto Unlock by time.
  11. 8 Access Groups (configurable per credential).
  12. Same small footprint as Keri’s Intelliprox BlueTM and sharing the same enclosure

An additional feature is the ability to perform gateway-wide anti-passback, opening up a whole market segment for this low cost controller. The Neutron controller is designed to work with Keri’s NXT readers in both 125kHz and 13.56MHz. Traditional 125 kHz Wiegand readers and keypads are not supported. Supplied inputs and relay outputs are fixed to supporting REX (Request to Exit), DPS (Door Position Switch) and door relay.


3.0 Wiring Diagrams

Keri’s Neutron Controller is a small, low cost, single-door controller that supports two reader connections. Up to 8 Neutron mini-controllers may be attached to a RS-485 network, originating at a PC or Keri appliance, to control 8 doors with the option of using IN and OUT readers.

Controller Wiring Diagram

Neutron has been designed with low cost and small physical size in mind, yet maintains a powerful feature set, nearly equal to Keri’s NXT controllers. In fact, Neutron runs on the Visual Doors version of Keri’s Door.NET software and maintains a 1000 credential capacity and a 16,000 event buffer (4000 offline).
