Resilient Technologies offers the Door Interlocking Terminal (DIT‑400) for larger secure zones that require coordination of up to four entry points. The DIT‑400 manages four doors and provides eight IN/OUT switch contacts. It features the same dual‑colour LED status lights and audible buzzer as the two‑door model, with green indicating permission and red indicating lockout. An optional switchless mode lets the LEDs alone govern access without external hardware.
Programming is achieved via a serial link using the DOTL protocol, allowing users to define interlock groups for each of the four doors. Typical supply voltage for this class of equipment is 24 V DC, with current draw not exceeding 600 mA. Standard indoor enclosures are rated IP20 and operate comfortably between - 10 °C and 60 °C.
This solution is suited to pharmaceutical plants, data‑center corridors, or multi‑airlock laboratory complexes where multiple doors must be sequenced. Resilient Technologies lists the unit as imported with a harbour trust tier; buyers should request lead‑time, MOQ and payment terms directly. Further technical details can be obtained through the company’s contact channels.

Before committing to purchase, confirm that the four‑door capacity aligns with your site layout and request a full technical datasheet that details LED logic, buzzer voltage and any optional relay outputs. Ask whether the unit has been tested to any safety or electromagnetic compatibility standards relevant to your industry.
Shipping will originate from the supplier’s Gurgaon facilities. Clarify the preferred Incoterm, typical lead‑time and packaging dimensions, as these are not disclosed in the listing. Discuss payment milestones directly with Resilient Technologies to ensure both parties agree on deposits and final settlement.
Arrange a factory pre‑shipment inspection that validates the interlock sequence for all four doors, LED colour operation and buzzer audibility. Request test certificates for supply voltage tolerance and temperature range, and consider on‑site functional testing for critical installations. Obtain any conformity or compliance documentation before the goods leave the factory.
