TOA Electronics RS-170 Outdoor Substation with Speaker and Call Button

The TOA RS-170 is a rugged call station designed for reliable communication in industrial, commercial, and outdoor environments. Equipped with a 4 cm cone-type internal speaker and a robust metal call button, this unit delivers clear and consistent audio signaling. Its stainless steel hairline panel and weather-resistant printed circuit board provide enhanced durability, ensuring long-lasting performance in harsh conditions, including high-traffic areas and locations exposed to environmental elements.

The RS-170 supports long-distance transmission using two-core shielded cable, maintaining signal integrity over distances up to 1.3 km (1421 yd) depending on cable thickness. The unit’s rated input of 1 W and rated impedance of 625 Ω (1 W / 25 V) ensures that messages are transmitted audibly and clearly, while the compact design allows for easy wall or enclosure mounting. This combination of rugged construction, reliable audio performance, and flexible installation makes the RS-170 ideal for factories, warehouses, schools, hospitals, and public facilities.

Engineered to operate in a wide temperature range from -10 °C to +50 °C (14 °F to 122 °F), the RS-170 provides dependable performance under various indoor and sheltered outdoor conditions. The weather-resistant PCB and durable construction protect the internal components from moisture and environmental stress, making this call station a professional solution for critical communication needs.
