The DeltaQuest door controller is a Universal 2 door (2 reader) controller built for third-party software. DeltaQuest gives access control and membership platforms simple, reliable I/O to drive doors, turnstiles, speedgates and maglocks – scaling to 32 access points from a single host over USB or TCP/IP.
Why DeltaQuest
-
Open by design – Integrates directly with third-party access or membership software via a straightforward command structure, so you can validate credentials in your app and trigger access on the controller.
-
Scales as you grow – Each module manages two readers/doors/lanes; expand up to 32 access points from one PC connection (USB or TCP/IP).
-
Reader-agnostic – Works with Nortech readers and many third-party readers/keypads; supports common output formats and interfaces used across the industry.
-
Installer-friendly – No local DIP switches/jumpers; everything is configured in software for a faster, cleaner install.
-
Built-in control I/O – Robust output relays to drive barriers/turnstiles/maglocks, Free Exit inputs per reader and aux outputs for extras like card capture or DVR triggers. Supports PINs up to 15 digits from connected keypads.
How it works (at a glance)
-
Your software reads a presented credential’s validity for that access point.
-
The reader’s ID data is passed to DeltaQuest and forwarded to your host.
-
If valid, your software sends a simple command back; DeltaQuest actuates the relay to unlock/open.

FAQ’s
Frequently asked questions
How many doors can I run?
Two per module (two readers), expandable to 32 access points from one PC over USB or TCP/IP.
Will it work with my membership/access software?
Yes – DeltaQuest is built for third-party integration; your software validates credentials and instructs the controller to unlock.
What reader types are supported?
DeltaQuest is compatible with Nortech readers and many third-party readers/keypads and supports common output formats. Your installer can select the tech that suits (RFID, keypad, etc.).
What power options are available?
Choose the PCB (12V DC) for custom housings or the enclosed model with an integrated 12V/3A PSU and intelligent fuse panel with power monitoring.
