System Sensor RTS2-AOS Smoke Detector

The System Sensor RTS2-AOS is a professional-grade multi-signaling remote test and reset station designed specifically for InnovairFlex 4-wire conventional duct smoke detectors. Built for centralized monitoring, this accessory allows technicians to manage up to two sensors from a single power board, facilitating efficient compliance testing in hard-to-reach HVAC ductwork. The unit operates on a 24Vdc power supply (20-29 VDC range) and features a bicolored LED system for immediate status diagnostics: green for standby, amber for trouble or maintenance, and red for alarm conditions. Unlike standard remote stations, the RTS2-AOS includes an integrated add-on strobe and a sounder with selectable continuous or temporal tones, ensuring both audible and visual notification in noisy mechanical rooms. The integrated keyswitch allows for discrete sensor selection, while the push-button enables total system resets. With a maximum wiring distance of 1,000 feet, this station is essential for large-scale commercial air handling installations requiring NFPA 72 and 90A compliance.

• Dual-Sensor Monitoring: Provides the ability to discretely monitor and test two separate sensors (such as supply and return) from one centralized remote test station.
• Advanced Diagnostics: Features multi-signaling LED indicators for standby, trouble, maintenance, and alarm, reducing troubleshooting time for field contractors.
• Enhanced Notification: Includes a factory-shipped add-on strobe (AOS) and 85 dBA sounder to meet high-visibility and high-noise requirements.
• Field Versatility: Supports sensitivity testing when used with a SENS-RDR reader and mounts easily to single- or double-gang electrical boxes.
• Industrial Durability: Rated for a wide operating temperature range of 14°F to 140°F, suitable for demanding rooftop and mechanical environments.

Which duct smoke detectors are compatible with the RTS2-AOS?
This station is designed exclusively for use with System Sensor InnovairFlex 4-wire conventional models, such as the D4120 or D4P120 power boards.

Can I test two different duct detectors with one station?
Yes, it can monitor two sensors connected to a single InnovairFlex power board in a 2:1 configuration. Use the keyswitch to toggle between Sensor 1 and Sensor 2 for individual testing.

What wire gauge should be used for installation?
Contractors should use 14 AWG to 22 AWG wire, ensuring that the total resistance remains below 25 ohms per interconnecting wire for runs up to 1,000 feet.
