3.19.1.1
ANTI PASS-BACK
Many Companies require a way in which they can prevent users from leaving the premises if they still have keys in
their possession.
One method now available for Wiegand Readers is to link the Traka Key Control system directly to an existing Access
Control system. Traka will update the Access Control system whenever a user has 1 or more keys booked out to them
or whenever a user has returned all the keys.
There is no development required and minimal configuration on the Access Control system to implement this solution
as it utilises the Anti Pass-Back feature of the Access Control system which is available in 99% of Access Control
systems.
Within the Access Control system it will be possible to configure Anti Pass-Back with two zones:
Zone A: Users with no keys
Zone B: Users with 1 or more keys
It will be possible to configure certain Doors or Turn-Stiles that are controlled by the Access Control system to prevent
users from passing through them if they are in Zone B.
So when a user takes 1 or more keys from the Traka Key Control system, the Traka Key Control system will inform the
Access Control system which in turn will place that user into Zone B, preventing them from leaving the site.
When a user has returned all the keys booked out to them to the Traka Key Control system, the Traka Key Control
system will again inform the Access Control system which in turn will place that user into Zone A, allowing them to
leave the site.
How does the anti pass-back link work?
To enable the Traka Key Control system to link directly to the Access Control system it is possible to provide the Traka
Key Control system with two Wiegand outputs. One output will relate to Zone A and the other output will relate to
Zone B. These outputs will then be connected directly to the Access Control system it the same way as the other
Access Control Card Readers.
When a user swipes their ID Card on the card reader attached directly to the Traka Key Control system, the Traka Key
Control system will allow or deny access to the System / Keys in the normal way but also buffer the users Card ID.
If the user was allowed access by the Traka Key Control system and the user takes 1 or more keys from the Traka Key
Control system, the Traka Key Control system will output the buffered Card ID on the Zone B Wiegand output,
informing the Access Control system that the user has taken keys.
When returning keys if the user was allowed access by the Traka Key Control system and the user has returned all the
keys booked out to them correctly to the Traka Key Control system, the Traka Key Control system will output the
buffered Card ID on the Zone A Wiegand output, informing the Access Control system that the user has returned all
the keys booked out to them.
The Traka Key Control system will also check if the keys have been returned to the correct slot and will not allow the
user to leave site until correctly returned.
Things to note...
If a user already has a key in their possession and they access the Traka Key Control system to take 1 or more
additional keys, the Traka Key Control system will not repeat the output to the Access Control system as it will already
be aware that the user has keys. The same applies if the user has no keys in their possession and they access the
Traka Key Control system and simply close the door without taking any keys.
The Access Control system will have to take into account emergency situations where it is not possible to return a key
to the Traka Key Control system.
