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.
