How to
Installing an RP Series Expansion Multi-sensor into a Dropped Ceiling Using the Mounting Springs
You install an RP Series expansion multi-sensor into a dropped ceiling using the mounting springs to properly fasten the device to a ceiling tile.
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.
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).
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.
Refer to the dimensional drawing before installing the multi-sensor.
