NetDCD Problems

Greatly improved communication speeds. About 10 times faster than the original DCD, if used with the Enhanced Site Control Unit (ESCU) or NetDCD.

Millennium NetDCD Problems

Quick setup steps:

1) Connect power and the Ethernet connection to the board

2) Connect to the board using the Configuration Utility (admin/password=admin/admin)

3) Change the DHCP mode to no, and assign a pre-determined IP address

4) Assign the correct gateway & subnet mask addresses

5) Ensure remote host is set to (used in 90% of installations) unless using controller to host function – if so, enter the IP address of the server as the remote host; in the software, use “controller to host.”

6) Change the “Owner ID” to what matches the “Controller Owner ID” precisely, or highlight the default “Owner ID,” “Demo. Not for resale”, delete it, then hit save. The board will then connect with any Millennium access control system that tries to communicate with it first.

(The “Controller Owner ID” can be found under Hardware Configuration)

Troubleshooting tips:

“The IP address, subnet mask, and gateway are all set correctly, but the site still isn’t coming online in the software”

A) Check the “Owner ID” and ensure that it is, character for character, the same as the “Controller Owner ID” in the software.

B) Restart all Ultra services from the diagnostics menu.

C) Make sure that the “online” box is enabling for the site controller in the programming.

D) Check that another device hasn’t already taken the IP address on the network.

E) Check that the Mac Address / IP Address isn’t blocked/is allowed on the network.

F) Check the encryption settings, that they are off or matching the software correctly.

G) Check if the remote host is entered correctly in the board configuration.

“The configuration settings will not save after changing them, then clicking the save button.”

A) Instead of using the web interface, use the configuration utility.

B) If this error is happening with using the configuration utility, download the latest version.

“The board does not appear on the list of devices when hitting search in the configuration utility” 

A) Factory default the board by following the complete install/hardware guide,

B) Ensure that the network is not blocking the MAC address.

C) Ensure that the computer firewall trying to connect with the board is turning off.

D) Ensure the computer trying to connect with the board is within the IP range of 192.168.0.XXX as after the panel is factory defaulted. The IP address becomes static @

“The doors or one door is not coming online.”

A) Ensure that the door address programmed in the NetDCD is not conflicting with the physical rotary address of another DCD, if a door, and SCU if a site.

Electric Strikes vs. Electrified Locks

Electric Strikes and Electrified Locks

Because electric strikes and electric locks operate in the same manner (opening a door from a remote location with unique access control system equipment), they are often confused with each other. Many people even use both terms interchangeably. However, electric strikes are very different from electric locks.

  1. Definition

Electric Strike

Replaces a standard, fixed door lock. It opens a door from a remote location. It is often accessing with special control equipment such as a keypad or card reader.

Electric Lock

Replaces a standard, fixed door lock. It opens a door from a remote location. It is often accessing with special access control system equipment such as a keypad or card reader.

       2. Functionality 

Activating the electric strike releases the strike keeper, opening the door and allowing entry.

Activating the electrified lock allows the user to turn the door handle and retract the latch bolt.

       3. Installation

Electric strikes are installing in the frame. Wires are generally storing inside the structure. Can install certain types in a door for paired openings.

It is installing on the door like a regular lock. It requires a “raceway” (an enclosed pathway for electrical wiring) through the door. A power transfer device such as an electric lock hinge or door loop transfers the electric current from the backside of the frame to the lock.

        4. Applications

Can use it on interior or exterior or security doors, new construction, or remodels.

In-field alterations of fire-rated doors may require prior approval from the Authority Having Jurisdiction (AHJ).

        5. Pros

Because mount on the door frame, electric strike installation is typically more accessible and faster than an electrified lock.

Its lower cost of installation is due to ease of installation.

Since it acts as a release, you can also use it on doors that use an automatic door operator.

The lockset can stay locked, but the strike releases to allow the power operator to swing the door open freely.

It offers a cleaner look than an electric strike.

Can argue that electrified locks are more secure since electric strikes are more visible and accessible for tampering.

Can use them on fire-rated security doors that require a “fail-safe” power mode due to building codes.

       6. Cons

Noticeable to the door user and thus does not provide a “clean” look compared to a built-in electrified lock. This visibility can make it more susceptible to tampering.

Cost is a factor since electric locks are more expensive than electric strikes. Installation charges are usually higher because installation is more involved, such as prepping the door for a raceway and accounting for the added power transfer device connecting the frame to the door.

Cannot use it on automatic door-operated openings.

 The latch bolt does not electrically retract, prohibiting the operator from opening the door freely.

        7. Power                            Requirement

It can be either 12V or 24V, usually DC but may be available in AC. Some models allow in-field selection, while others must be ordered with the specifications pre-determined.

        8. Power Fail                     Modes

Can be “fail-safe” or “fail secure.” Some models allow in-field selection, and others must be ordered with the preference pre-determined.

Can be “fail-safe” or “fail secure.” Must order most models with the preference pre-determined.

      9. Fire Rated                    Doors

Must be used on “fail-secure” fire-rated doors, which means, if the power is cutting, the latch will be securely capturing behind the strike keeper.

A “fail-safe” electric strike is not allowed on a fire-rated door because no latching support provides during a power outage.

It can be used on fire-rated doors in either “fail-safe” or “fail secure” mode, as the lock always maintains positive latching.

 However, additional safety codes may determine which model of lock can be using.

 Check with your local Authority Having Jurisdiction (AHJ) for requirements.

Is electric strike a good alternative?



When discussing door hardware, a door electric strike, refers to the metal plate or assembly that’s installed into or onto a door frame to “catch” the latch or bolt to hold the door closed.

Where can you find an electric strike?

  • Commercial Buildings
  • Banks
  • Technology Centers
  • Warehouses
  • Industrial Facilities
  • Technology Centers
  • Convention Centers
  • Long Term Living Facilities
  • Stairwells
  • Apartment buildings
  • Hotel rooms
  • Schools and Universities
  • Nursing homes

Electric strikes replace a standard door strike and are connecting to a power supply.

When an electric strike is activated, it releases the latch, unlocking the door.

Electric strike locks remain locked from the outside at all times. When the door closes behind you, it automatically returns to a locked position. Electric strike locks are opened from the inside by pressing a panic bar or other manual release device.

Fail-secure Electric Strike vs fail-safe Electric Strike

Fail-secure Electric strike: A fail-secure electric strike is required for a fire-rated opening and will remain locked during a power outage. That is the safer of the two options since it will keep the building secure and will not allow entry into the building if the power goes out. Of course, exiting inside is always possible with a panic bar or other exit device since the electric strike lock outside.

Fail-secure Electric strike: A fail-safe electric strike will unlock in the event of a power loss, allowing everyone free access.

Magnetic locks, in comparison, are all fail-safe. Therefore, in a power outage, a magnetic lock will remain unlocked and not function. That creates a severe security risk for a building that needs to stay secure in the event of a power outage. For this reason, electric strikes are recommending over magnetic locks.

Benefits of Electric strikes

Security: Electric strikes are a very secure and safe option for latching a door since you can only activate them with a card, pin, or remote device associated with the strike.

Convenience: When it connects to a remote system, you can allow someone entry from the comfort of your desk or bedroom with the push of a button. An electric strike attached to a pin code can also be helpful since no key is necessary, and you can choose who to share the code with.

Easy installation: Installation of electric strikes is quicker and simpler. That’s because electric strikes are mounted only on the frame. Installing them requires only cutting at the structure. Electronic locks, on the other hand, require prep on the door itself, which can complicate.

Low-cost installation: Because electric locks are easier to install, as explained above, a hired contractor or handyman should take less time to install them; therefore, your labor and materials cost should be similar to a standard strike installation.

Two Challenges of Electric Strikes

Don’t lose your card!

If you’re using an electric strike that requires a card for access comtrol system, be sure you keep your card in a safe place. These cards are sometimes expensive to replace. More importantly, you may not be able to enter your property or office building after hours.

The keypad or card reader used to activate the electric strike is quite visible in access control solutions. That, of course, is necessary for people to be able to enter the building quickly after entering a code or swiping a card. However, since it is visible, it may be more prone to tampering or vandalism. However, most electric locks sold today are very safe, and “hacking” a code presents too big of a challenge for would-be burglars.
