GENERAL INFORMATION
The National Fire Protection Association (NFPA) has published codes, standards, and recommended practices for the installation and use of this product.
It is recommended that the installer be familiar with theses requirements, with
local codes, and any special requirements of the local authority having jurisdiction. For further information, consult NFPA 72 and 90A requirements.
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
• AOS-Add-On-Strobe (included on RTS2-AOS model)
• Provisions for single- or 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.)

INSTALLATION
Installing the Mounting Plate
1. Secure the mounting plate to a single- or 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.

OPERATION
The green “Standby” will blink every 5 seconds whenever the duct smoke
detector is receiving power. The amber “Trouble” LED is lit when the duct
smoke detector sensor is missing or the detector cover is removed. The delay
to indicate a trouble condition once the cover is removed depends on the dip
switch setting on the duct smoke detector power board. An LED with amber
blink every 5 seconds indicates that the sensor is in “Maintenance” which indicates that the sensor needs to be cleaned or replaced. See Table 1 LED Status
Indication for a detailed list of indications.
ENABLING THE TEST/RESET/SENSITIVITY OPERATION
Insert the key and turn to select either sensor 1 or 2. This will enable the
selected sensor to be tested, reset, or sensitivity read. Note all test/reset/sensitivity functions can be initiated with the outer cover installed or directly on
the mounting plate.
TEST FUNCTION
With the desired sensor selected by the key, press and hold the Test/Reset button for 2 seconds. If the sensor is within its sensitivity limits, the device will
alarm within the next 3 seconds. The RTS2 will not initiate a test condition if
a trouble exists on D4120.
ALARM INDICATION
Once the Test/Reset button has been pressed, the red alarm LED will illuminate and the horn will sound (within 5 seconds). If an AOS (add-on strobe) is
installed, it will flash.
RESET FUNCTION
Reset is a common function to both sensors. Press and release the Test/Reset
Button. The red alarm LED should turn off on both sensor LEDs and the horn
will cease sounding. The strobe will cease flashing (if optioned). The current
sensor status will be indicated (See Table 1). Note, the key switch must still be
selected for one of the sensors in order for the reset function to be enabled.
SENSITIVITY FUNCTION
When the key is installed and sensor 1 or 2 is selected, the selected sensor
sensitivity can be read via a SENS-RDR (sold separately).
1. Select the desired sensor with the key.
2. Press the test button on the SENS-RDR. “Ready” should appear on the
SENS-RDR display.
3. Hold the SENS-RDR up to the oval indentation on the mounting plate or
outer cover (if installed). Within 10 seconds the sensor sensitivity will be
displayed.
DISABLING THE TEST/RESET/SENSITIVITY OPERATION
When the key switch is returned to the neutral (vertical) position and
removed, the Test/Reset button will be disabled.

WARNING
The sounder or sounder/strobe combination will not operate if the power is
cut off for any reason.
If power is cut off for any reason, the sounder or strobe/sounder combination
will not provide the desired audible or visual warning.
The sounder may not be heard. The loudness of the sounder meets or exceeds
the current Underwriters Laboratories’ standards. However, the sounder may
not alert a sound sleeper or one who has recently used drugs or has been
drinking alcoholic beverages. This sounder may not be heard if it is placed in
an area that is separated by a closed door, or if it is located on a different floor
from the person in a hazardous situation, or if it is placed too far to be heard
over ambient noise, such as, traffic, air conditioners, machinery or musical
appliances that may prevent alert persons from hearing the alarm. For these
The Sounder and add-on strobe are for supplemental signaling only.
The signal strobe may not be seen. The visual warning signal is suitable for
direct viewing and must be installed within an area where it can be seen by
building occupants. The strobe must not be installed in direct sunlight or areas of high light intensity where the visual flash might be disregarded or not
seen.
The strobe may not be seen by the visually impaired.
The signal strobe may cause seizures. Individuals who have a positive photic
response to visual stimuli with seizure, such as epileptics, should avoid prolonged exposure to environments in which strobe signals, including this
strobe, are activated.
reasons, System Sensor recommends that sounders (85dBA minimum at 10
feet) used in a residence shall be placed on every level and in every bedroom
that does not have a smoke detector with a built-in sounder.)
The sounder may not be heard by persons who are hearing-impaired. In this
case, a visual indicator shall also be used.
