OEM Access Control Integration Solutions

Nortech's DeltaQuest OEM range provides hardware I/O support for third-party access control and membership management software, enabling seamless integration between existing PC-based systems and physical access control hardware. Designed specifically for software developers, system integrators, and leisure facility operators, DeltaQuest controllers bridge the gap between membership databases and door control hardware.

The DeltaQuest system supports up to 32 access points via a single USB or TCP/IP connection, with each 2-door controller managing readers, keypads, barriers, and turnstiles. The simple command structure minimizes software development complexity, while comprehensive support for Clock & Data, Wiegand, and RS232 reader formats ensures compatibility with virtually any card reader technology. This makes DeltaQuest ideal for gym management systems, leisure centers, membership-based facilities, and custom access control applications requiring integration with existing software platforms.

Available as a PCB-only version for integration into third-party housings or as a complete unit with integral power supply in an attractive wall-mount enclosure, DeltaQuest offers flexible deployment options. The system's plug-and-play USB connectivity and configuration-free operation enable rapid deployment without complex DIP switch settings or local programming, reducing installation time and technical complexity.

Frequently Asked Questions
What is OEM access control, and who is it designed for? Arrow 1

OEM (Original Equipment Manufacturer) access control provides hardware interface controllers that integrate with third-party software systems, rather than operating with proprietary management software. The DeltaQuest range is specifically designed for software developers, system integrators, and businesses using membership management software (particularly in leisure and gym facilities) who need to control physical access points. Rather than replacing existing software, DeltaQuest provides the I/O support to connect card readers, keypads, and barriers to your existing database or membership system via simple USB or TCP/IP connectivity.

Can DeltaQuest integrate with gym membership software? Arrow 1

Yes, DeltaQuest is ideal for gym and leisure facilities using third-party membership management software. The system is compatible with several leading membership database systems and uses a simple command structure that many gym management software packages already support. When a member presents their card or enters a PIN, DeltaQuest sends the credential data to your membership software, which validates the member and sends back a simple "grant access" or "deny access" command. This allows seamless integration between your member database and physical turnstiles, barriers, or doors without replacing your existing software.

How many access points can a DeltaQuest system control? Arrow 1

A DeltaQuest system can control up to 32 access points (doors, barriers, or turnstiles) via a single USB port or TCP/IP network connection on your PC. Each DeltaQuest controller module manages 2 access points with support for 2 readers per access point (read-in/read-out capability). You can daisy-chain up to 16 DeltaQuest modules together using RS485 communication, all controlled from one master module connected to your PC. This scalability makes it suitable for everything from small single-door installations to large multi-entry leisure facilities.

What reader technologies does DeltaQuest support? Arrow 1

DeltaQuest supports all Nortech reader technologies plus many third-party card readers and keypads. Supported interface formats include Clock & Data (ABA Track 2), Wiegand (26-bit and other formats), and RS232. This includes 125 kHz proximity readers, Mifare and LEGIC smart card readers, magnetic stripe readers, biometric readers, and numeric keypads supporting PINs up to 15 digits. Each reader interface also includes Free Exit input and auxiliary outputs for controlling additional devices like card capture readers or DVR systems.

What's the difference between the PCB version and the enclosed version? Arrow 1

The **DeltaQuest PCB** (DQ-S2-PX) is supplied as a bare circuit board for integration into your own custom enclosure or existing equipment housing, offering maximum flexibility for OEM applications and system integrators. The **DeltaQuest with PSU** (DQ-S2-PH) comes in an attractive wall-mount plastic enclosure (312 × 312 × 100mm) with an integral 12V DC 3A power supply and intelligent fuse panel providing managed power to access devices. Choose the PCB version for custom installations or the enclosed version for ready-to-install applications requiring comprehensive power management.
