1. Neutron integration requires you to install Doors.NET v4.3.5.0 or later.
   
2. The Neutron hardware type cannot co-exist with other hardware types. When Neutron is enabled on your license only Neutron controllers can be used on the system.
   
3. Neutron can only be configured and managed using the Visual Doors software. Neutron hardware cannot be used with the Doors.NET admin client.
   

To use the Neutron controllers you will need a license key with the Neutron hardware type enabled. The license key with Neutron enabled will automatically be configured to support up to 8 controllers. You can either contact Keri Systems sales for a license key or you can generate your own key at the following URL: license.kerisys.com.

3.1 Verify Neutron is Enabled on Your License

This section assumes you have already successfully installed the Doors.NET software and have activated your license:

Note: The Neutron hardware type cannot co-exist with other hardware types. When Neutron is enabled on your license only Neutron controllers can be used on the system.

1. From Windows Start menu go to Doors.NET >> License Manager.
2. When the License Manager window opens, select Application Server.
3. Click the License tab on the right pane.
4. Locate the Capacities section and verify that NXT-NEUTRON is set to 8 controllers.
   
5. Scroll down to the Supported Hardware section and verify that NXT-NEUTRON is set to True.
   
6. If Neutron is enabled you will be able to add the Neutron gateway.

4.0 Cable Recommendations

• Input Power - Belden 8461 - two conductor, stranded, AWG 18 wire
• NXT Readers - Belden 8723 (or equivalent) - this is a 2-pair shielded, stranded, twisted cable.
• RS-485 Network Cable - Belden 9501 - two conductor, shielded, twisted pair, stranded, AWG 24 wire or larger (note that increasing the wire gauge does not increase the total network length...
  - The total network length is 4,000 feet/1,000 metres.
• Input and Output Connections - Belden 8461 - two conductor, stranded, AWG 18 wire.
  
  Note: The Lock Output relay may require a heavier gauge of wire depending upon the current demands of the lock and the length of the lock wiring run.
  
  
• USB Adapter to PC Extension Cable - A USB extension cable can be used to extend the connection between the PC and the USB adapter - this cable should be a maximum length of 20 feet.

5.0 Wiring Diagrams

5.1 Controller Wiring Diagram 

5.2 Lock Wiring Diagrams

Fail-Safe Lock Wiring

A fail-safe lock requires power to keep the door locked. So if power should fail at the lock, the door will unlock - allowing quick entry or egress. A typical fail-safe lock is a magnetic lock.

Fail-Secure Lock Wiring

A fail-secure lock requires power to unlock the door. If power fails at the lock, the lock will automatically lock and will not allow entry or egress. A fail secure door ensures a secured area remains secure regardless of the situation.

Notes: 

• Transorbs are provided with the controller ship kit. They are used to protect the controller from voltage spikes induced on the port wiring. Keri strongly recommends wiring in the transorbs provided as close as possible to the lock.
• The Transorbs that Keri provides are non-polar; they can be installed in either orientation.

Isolation Relays

For locking devices that may induce heavy voltage spikes – Mag Locks and devices with heavy-duty solenoids such as turnstiles, vehicle gates, and overhead doors – Keri recommends using isolation relays. Keri has an Isolation Relay Kit (p/n IRP-1). Please refer to the IRP-1 Isolation Relay Installation Guide (p/n 01833-001) for detailed information.

6.0 LED and Jumper Definitions

(See Neutron controller diagram for location of the LEDs and jumper)

• J2 (TAMPER): Provides a normally-closed tamper input to the controller.
• D15 (PWR FLT): Indicates a short on the controller or if the power lines are reversed.
• D20 (PWR): Solid green indicates when the controller is powered-up.
• D19 (3.3V): Solid green indicates the output of the controller's onboard DC converter.
• D14 (TAMP): Solid red to indicate when the controller tamper input is active.
• D2 (BUSY): Solid red when the controller is being reset or during firmware upgrade.
• D24 (RS485): Quickly flashing amber RS-485 reader communication).
• D25 (O/C): Solid red to indicate if there is over-current on the controller's reader port.
• D22 (FLSH): Solid red to indicate when the flash memory chip is active.
• D8 (RELY): Solid red to indicate when the controller strike relay is active.
• D1 (ADDR): Controller address number (i.e blinks 3 times for address #3).
• D6 (ON): Solid green to indicate the controller is online.
• D7 (OFF): Solid red to indicate the controller is offline.

7.0 Controller Installation Guidelines

• Mount controllers in environmentally suitable areas - they require protection from temperature and humidity extremes.
• Ensure each Neutron controller is receiving between 12 and 14VDC - longer power lines cause a drop in voltage at the end of the run.
• Connect all Neutron controllers to a quality earth-ground.
• Connect the RS-485 shield wire to the GND connection of the USB-RS-485 adapter. Do NOT connect the shield wire to the frame ground of any of the controllers is this may cause a ground loop.
• Use the enclosure as a mounting template to mark drilling holes for permanent mounting.
• Route all controllers on the RS-485 network in a single, continuous daisy-chain. NOT in a star or a ring configuration.
• Add transient suppression across electric devices attached to the controller output. A transorb is supplied with the controller and it should be installed as close as possible to the locking device.
• Use an isolation relay (P/N IRP-1, or equivalent) if connecting to a parking gate, a turnstile, or any application that uses a large electric motor.
• The industry standard maximum RS-485 network length is 4,000ft/1000m.
• The RS-485 recommended cable type is Belden 9501 (or equivalent) - two conductor, shielded, stranded, twisted pair. Recommended wire gauge is AWG22.
• NXT reader extension cable type is Belden 8723 (or equivalent) - four conductor, shielded, stranded and twisted RS-485 wires. Recommended wire gauge is AWG-22.

8.0 Neutron Controller Connection

1. Connect the USB end of the cable into an available USB port on the host PC.
2. The adapter should be installed automatically and you should be able to find it in Windows Device Manager.
3. Hard-wire a connection between RS-485+ of the adapter to TB2-RS-485 A+ of the first controller.
4. Hard-wire a connection between RS-485- of the adapter to TB2-RS485 B- of the first controller.
5. Connect the RS-485 shield-drain to the GDN connection of the USB adapter.
6. The RS-485 +, RS-485 - and shield drain are daisy-chained to all other Neutron controllers on the network.

Notes:

• Every system requires a USB-RS485 adapter. The adapter, once installed will automatically be assigned a COM port and auto-configuration scans for controllers via this COM port.
• The adapter's assigned COM port number can be viewed in Windows Device Manager (Control Panel >> Device Manager).

10. Controller Factory Reset

Before adding the controller to the Visual Doors software, you should factory reset the controller. The factory reset will clear all configuration and event history (but will, of course, retain the controller's MAC address) - so it can be found again via Auto-config.

1. Down-power the controller.
2. Hold down the S1 button while applying power.
3. Continue to hold down the S1 button...
4. Release the S1 button when the BUSY LED (D2) stops blinking.
5. The FLASH LED (D22) will be solid red for aproximately 30 seconds.
6. The FLASH LED (D22) will go off and the offline LED (D7) will then be solid red.
7. The controller is now reset and ready for setup.
   
   Note: If you release the S1 button too soon, or too late then no reset will occur.
   

11.0 Setup the Neutron Gateway

The Neutron gateway provides the communication link between Visual Doors and the Neutron network.

Note: If you have not yet activated your license key: following Doors.NET installation, you will be prompted to run the License Manager and before the License Manager opens you will be prompted to enter your license key... The License Manager is used to create the gateway.

1. When the License Manager window opens, refer to the list of installed clients and services on the left.
2. You will see the Neutron gateway listed but it will state: 'Licensed Needs Configuration'.
   
   
   
   
3. Select the gateway from the list then click the SETTINGS button.
4. Enter a name for the new Neutron gateway >> click OK.
5. You will be prompted to start the gateway service.

9. Any doors that are not selected won't be part of the access group.

10. Once you have selected all the required doors the access group will be created, there is no need to save the access groups page.

11. You will now be able to assign the access group to cardholders (see section 14).
    

18. Operate Doors

Visual Doors allows you to unlock, lock, lockout or lockdown any enabled doors on the system.

1. From the Visual Doors home screen, click the Hardware tile.
2. Select the door on the left that you wish to command from the software.
   
   - Temp Unlock - The door will unlock for the duration of the strike time (the same amount of time the door will unlock if you present a valid card or from a Request-to-Exit). The door strike time can be adjusted in door setup (see section 13.2).
   
   - Unlock - The door will unlock and will remain unlocked... unless manually locked, put into Lockout or Lockdown or overridden by the stop time of an auto-unlock schedule.
   
   - Lock - The door will be locked and will remain locked... unless manually unlocked or overridden by the start time of an auto-unlock schedule.
   
   - Lockout - (also referred to as Emergency Lockout) will immediately 'lockout' the door and prevent access from being granted with a valid card. Access will, however, still be allowed using request-to-exit buttons.
   
   - Lockdown - (also referred to as Emergency Lockdown) will immediately 'lockdown' the door and prevent access from being granted with a valid card. Access will also not be possible using a request-to-exit button.
   
   Note: If a door is disabled it will not appear on the Unlock Doors screen.

19.0 Auto-Unlock Schedules
