Overview

The GJD393 (D‑TECT X4) is a plug‑in expansion module for GJD’s D‑TECT X wireless receiver (GJD392). It adds four additional wireless detector channels to a D‑TECT X receiver, allowing the receiver to be expanded from its base 4 channels up to a maximum of 16 channels when multiple modules are fitted. This module is designed to be installed inside the D‑TECT X receiver enclosure and connects via the receiver’s expansion connector.

• Adds 4 detector channels — expand the receiver capacity by four per module.
• Expandable — multiple D‑TECT X4 modules can be fitted so one receiver supports up to 16 wireless detectors.
• Plug‑in design — slides into the receiver enclosure slot and connects via the receiver ribbon/expansion connector.
• Compatibility — for use with GJD D‑TECT X receiver family (e.g. GJD392).
• Compliance — CE marked; sold with typical limited manufacturer/reseller warranty (commonly 2 years).

Use & installation

This is an expansion accessory only — it is not a standalone detector. It must be installed into a compatible D‑TECT X receiver by a qualified installer following the manufacturer’s instructions. Refer to the GJD D‑TECT X installation manual / datasheet for slot fitting, connector orientation and configuration details.

Safety & compliance

• CE marked. Check local regulations for UKCA marking requirements if needed.
• Follow official installation instructions and wiring practices. Power down the receiver before fitting expansion modules.
