Product Features & Benefits

Each reader control module is provided in an attractive wall mount cabinet and can manage up to two ID devices and operate their associated barriers or turnstiles via robust output relays.

Each DeltaQuest module collects ID data from the attached card readers or keypads and sends it together with the identity of the reader/keypad to the third-party software via the master module. If the software identifies that the ID data is valid, it is able to permit access to the user through the barrier or turnstile by sending a simple command to the corresponding DeltaQuest module via the master.

The DeltaQuest is ideal for use in the leisure industry when combined with third-party membership software.

The DeltaQuest is compatible with all Nortech’s reader technologies and can support many third-party readers and keypads.
