The System Sensor RTS2 and RTS2-AOS multi-signaling accessories are designed for use with System Sensor InnovairFlex 4-wire conventional duct smoke detectors only. The accessory has two bicolored LEDs that indicate the sensor status of up to two connected duct smoke detectors. The key switch on the unit can be used to select a connected duct detector sensor (either sensor 1 or sensor 2), and the selected sensor can be tested or both sensors can be reset simultaneously using the test/reset button. LED status indications include: Standby (green blink), Trouble (amber), Maintenance (amber blink) and Alarm (red).
With the key switch selected, there is also the capability of obtaining a sensitivity measurement of the selected sensor using the SENS-RDR sensitivity reader (sold separately).
Specific Features of the RTS2 and RTS2-AOS include:
•Standby (Green Blink), Trouble (Amber), Maintenance (Amber Blink) and Alarm (Red) LEDs to indicate detector status
•Keyswitch to select desired sensor, enable test/reset button and sensitivity reading
•Test/reset button
•Sensitivity reading ability with SENS-RDR (sold separately)
•Selectable continuous or temporal tone
H0621-00
• AOS-Add-On-Strobe (included on RTS2-AOS model)
• Provisions for singleor double-gang box mounting
• Ability to discretely monitor two sensors when duct smoke detectors are configured in a 2-to-1 set up (See InnovairFlex duct smoke detector manual for reference.)

NOTE: If polarity of Acc. (+) and Acc. (—) are reversed, an Amber LED on sensor 2 of the duct smoke detector power board will exist indicating a trouble condition.
Installation
Installing the Mounting Plate
1.Secure the mounting plate to a singleor double-gang electrical box with
(2) mounting screws provided. Note: If mounting to a single-gang box, the Add-On Strobe (AOS) must be removed prior to mounting. To remove the AOS, squeeze opposing sides lightly next to arrows and slide vertically.
2.If applicable, install the AOS onto the mounting plate as shown in Figure 2. Note, the RTS-AOS includes the AOS.
NOTE: installation per ULC S524-02
Temporal Sounder
The RTS2 accessory provides the option of sounding a continuous or temporal pattern. The RTS2 will default to sound in a temporal pattern. For a continuous pattern, remove the jumper located just to the right of the “Strobe” text on the mounting plate as shown in Figure 2.
Wiring
Wire the RTS2 as shown in Figure 3, for InnovairFlex 4-wire conventional duct smoke detectors. Limit wire runs to 25 ohms or less per interconnecting wire.
NOTE:
1.If polarity of Acc. (+) and Acc. (—) are reversed, an Amber LED on sensor 2 of the duct smoke detector power board will exist indicating a trouble condition.
2.One RTS2 can be wired to only one InnovairFlex power board.
3.If Aux. (+) and Aux. (—) wires are reversed, the strobe and sounder will not function.
Installing the Outer Cover
1.Install the outer cover on the mounting plate by sliding the outer cover over the upper tabs of the mounting plate as shown in Figures 4 and 5.
2.Tighten the outer cover mounting screw located at the bottom of the device. H0626-00 Note: The mounting screw can be replaced with the provided tamper resistant
Torx screw, if desired.
