Neutron
Economical Single-Door Controller DATA SHEET
Up to 8 Neutron controllers can be networked together to provide a small system,
with the option of “in” and “out” readers.
• Economical mini-controller for a single door
• Works exclusively with Keri’s Visual DoorsTM software
• Networkable via RS-485 for up to 8 controllers
• Supports Keri NXT and NXT-E readers
• Capable of In/Out access using Keri’s a NXT-E reader in
conjunction with a standard NXT reader
• 1000 credential capacity
• 4000 Event buer (oine)
• Equipped with dedicated inputs for REX & Door Sense
• Form “C” Relay for door control
• Congurable for: Lock Time, Auto Unlock by time
• 8 Access Groups congurable per credential
• Same small footprint as Keri’s Intelliprox BlueTM and sharing
the same enclosure
Keri’s Neutron Controller is a small, low cost, single-door controller. 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
both in/out readers.
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 4,000 event buer (oine).
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 xed to supporting
REX (Request to Exit), DPS (Door Position Switch) and door relay.
