Installing an RP Series Expansion Multi-sensor on an Octagon Junction Box Using the Mounting Ring

You install an RP Series expansion multi-sensor on an octagon junction box using the supplied mounting ring to properly fasten the multi-sensor to the junction box.

The RP Series expansion multi-sensor can be installed on a dropped (suspended) ceiling, a drywall ceiling, or a junction (gang) box.

The multi-sensor is designed to be installed with the passive infrared (PIR) sensor facing down. Installing the multi-sensor on a wall will reduce the coverage range of the PIR sensor.

Notice

REDUCED SENSOR COVERAGE RANGE

Always install the device with the passive infrared (PIR) sensor facing down.

Failure to follow these instructions can result in reduced device performance.

The multi-sensor must be professionally installed to comply with the following rules and regulations:

  • Part 15 of the Federal Communications Commission (FCC) rules

  • Innovation, Science and Economic Development Canada (ISED) licence-exempt Radio Standards Specifications (RSSs)

  • 2014/53/EU Radio Equipment Directive (RED) of the European Union (EU).

For more information, see RP Series Expansion Multi-sensor Regulatory Compliance and Approvals .

The multi-sensor is typically installed on a dropped ceiling. For that reason, the multi-sensor is delivered with three flexible mounting brackets (springs) preinstalled on the device. The mounting springs enable quick and easy installation of the multi-sensor on a dropped ceiling. The installation requires a clearance hole with a diameter of 75 to 76 mm (2.95 to 3.00 inches) in the ceiling tile.

The multi-sensor also comes with a mounting ring, which enables the following alternative installation methods:

  • Installation on a junction box

  • Installation on a drywall ceiling

The multi-sensor can be installed on a junction box when there is no ceiling and space is opened to plenum. The installation requires an octagon junction box of size 4.0 inches (102 mm) and a minimum depth of 1.0 inches (25.5 mm).

Tip:

You can use the two alignment notches on the mounting ring to position the device.

The mounting ring also makes it possible to install the multi-sensor on a drywall ceiling using an appropriate anchoring system. The installation requires a clearance hole with a diameter of 75 to 76 mm (2.95 to 3.00 inches) and two mounting holes that fit number 6, 8, M3, or M4 screws (with or without anchors) in the drywall ceiling. You can use the 1:1 drill template in the installation sheet, which comes with each multi-sensor, to measure out the location of the holes. You can also use the mounting ring to measure out the holes.

REDUCED SENSOR COVERAGE RANGE

Always install the device with the passive infrared (PIR) sensor facing down.

Failure to follow these instructions can result in reduced device performance.

Important:

The mounting ring supplied with the multi-sensor fits octagon junction boxes that have a size of 4.0 x 4.0 inches (102 x 102 mm) and a minimum depth of 1.0 inches (25.5 mm).

To install an RP Series expansion multi-sensor on an octagon junction box using the mounting ring

  1. Refer to the dimensional drawing before installing the multi-sensor.

  3. Align the keyholes slots on the mounting ring to the mounting screws installed in the junction box and then rotate the mounting ring clock-wise until the ring is retained. Tighten the screws to fasten the ring.

  4. Connect the room bus cable(s) to the multi-sensor.

    For more information, see Connecting RP Series Expansion Modules and Multi-sensors to RP-C .

  5. Configure the room bus address for the multi-sensor using the rotary switch on the device.

    For more information, see Configuring the Room Bus Address for an RP Series Expansion Multi-sensor .

  6. Attach the multi-sensor to the mounting ring by inserting the locking tabs on the mounting ring into the keyhole slots on the back of the multi-sensor. Rotate the multi-sensor clock-wise until it locks into place.

    Tip:

    You can use the two alignment notches on the mounting ring to position the device.
