PIN 3 - ENTUCX / PIN 9 - EXTUCX (Unauthorized Passage)
Description
An output contact is generated when a user completes an unauthorized passage (i.e., tailgating after
an authorized passage) in the appropriate direction. This is typically referred to by Alvarado as an
“unauthorized passage” output.
Purpose and Customer Use
These are important outputs to monitor as they identify unauthorized passages. The outputs are typically
used to identify the time and location of unauthorized passages. This allows review of the unauthorized
passage on security camera footage (if available).
PIN 4 - ENTALRX / PIN 10 - EXALRX (Unauthorized Entry/Exit)
Description
An output contact is generated when a user enters the turnstile without the turnstile receiving an
authorized passage signal (ENTACC / EXTACC or ENTOVR / EXTOVR).
Purpose and Customer Use
This output is generated when a user gets close to the barrier before the turnstile receives an authorized
entry or exit signal. This can be caused by users entering the turnstile too far before presenting their
credentials, or by users presenting their credentials and entering the passage area before the access
system sends an authorization signal to the turnstile.
Customers typically do not monitor unauthorized entry/exit outputs, but they can be useful to monitor for
a short time after installation. A large number of unauthorized entry/exit outputs can indicate that further
user training is required, or that there may be adjustments required with respect to the card reader or the
access system response time.
PIN 13 - BLKSEN (Blocked Sensor)
Description
An output contact is generated when any of the turnstile’s transmit / receive sensors in the operational
sensor arrays cannot communicate for a defined time period (factory default is 15 seconds). This output
is generated without regard to the state of the panels (open or closed).
Purpose and Customer Use
This output is an important output to monitor. It would provide notification of a person or object lingering
in the turnstile passage area or, as an example, if an object (such as a piece of gum or putty) was
inhibiting communication between the sensors. Security camera footage (if available) can be used to
review the situation surrounding generation of this output if desired.
