Wired Device Grothe ETA 502 G Bronze

The Grothe ETA 502 G Bronze is a wired device finished in a bronze colour, designed for straightforward integration into building entry and communication systems. It accepts both AC and DC power within a voltage range of 5–12 V, and its compact body measures 98 mm in width, 15 mm in depth and 62 mm in height. The unit is intended for fixed wiring installations where a slim profile and durable metal-look finish are required.

Advantages

The ETA 502 G Bronze combines a narrow footprint with compatibility for both AC and DC supply, allowing flexible installation in different electrical environments. Its compact size makes it suitable for mounting on narrow surfaces or in constrained spaces while the bronze finish offers a discreet, corrosion-resistant appearance that blends with many architectural styles. The device’s simple wired connection ensures reliable, interference-free operation compared with wireless alternatives.

How to use

Install the wired device following the site’s electrical regulations and switch off power before connecting. Position the unit on the chosen mounting surface and secure it with appropriate fasteners for the substrate. Connect the device to the building’s low-voltage supply, observing polarity when using DC and ensuring correct terminals for AC. After wiring, restore power and verify correct operation through the associated entry or communication system. If integrating with an existing intercom, refer to the system wiring diagram to match signal and power lines.

Usage recommendations

For reliable long-term performance, use a regulated 5–12 V power source within the specified range, protect wiring runs from moisture and mechanical damage, and perform installation in compliance with local electrical codes. When mounting outdoors or in exposed locations, ensure adequate sealing and choose suitable fasteners to maintain the bronze finish and prevent corrosion at attachment points.
