  • Access Level “Where”
  • Time zone with calendar to control “When”
  • Start and Expiry date “How long for”

How it Works

Dark Crystal Features

Dark Crystal readers take full advantage of the two-way communication in the P4 reader interface. Saving connections and installation time this feature also provides for a much richer and more informative user experience from the access control system.


The stand by illumination of a reader is helpful in most poorly lit situations. However, this, can make the reader at target when in an unsupervised vandal vulnerable location.

Brightness Control

Dark crystal readers introduce, for the first time, programmable brightness of the standby status indication. Adjustable is 10 steps from off to full brightness.

There are occasions when, the normally useful, user feedback beep sounds form a reader can be; inconvenient, distracting or just annoying.

Volume Control

Dark crystal readers introduce, for the first time, programmable Volume of user feedback sounds. Adjustable is 16 steps from off to full volume.

Alarm indication at a door can be very useful. Normally this would mean fitting additional hardware to give that Alarm Notification.

Integrated Alarm

Dark Crystal readers have a built in alarm sounder and strobe light.

Status indication is very useful to users of the access control system. Lock status, Interlock with another door etc.
