TOA RS-170 N-8000 Series Wired Intercom Sub-Station

The TOA RS-170 is a wired intercom sub-station designed for integration with the N-8000 and N-8010RS exchange systems. It targets security integrators and facility AV teams who need a reliable, hardened call point at entry doors, loading docks, parking facilities, or perimeter access points where both indoor and outdoor exposure is a concern. Communication runs over two-core shielded twisted pair cable, keeping the installation straightforward and interference-resistant across long cable runs.

Where many budget sub-stations use plastic housings that degrade quickly in high-traffic or exterior environments, the RS-170 uses a stainless steel hairline-finish faceplate with a weather-resistant circuit board coating, making it a practical choice for applications where vandalism or moisture exposure is likely. A call button with LED indicator gives users clear tactile and visual feedback without requiring additional signaling hardware. Half-duplex conversation keeps voice paths clean and eliminates feedback looping common in simpler intercom designs.

The RS-170 fits a standard 2-gang deep electrical box, which allows flush-mount installation consistent with architectural finishes. The optional YC-302 flush-mount box provides a matched solution for clean panel integration. Transmission range scales with conductor gauge, supporting cable runs well suited to campus, warehouse, or multi-building security installations.
