Installing the wireless battery-powered switch, fourfold, Zigbee®

Signal range

The point-to-point indoor range is ± 10 m. In open spaces, the RF range could reach 30 m.

Battery-powered or energy-harvesting Zigbee^® devices do not function as repeating nodes in a Zigbee^® network. They only act as receiver nodes and cannot be used to extend the network. Only Zigbee^® devices that are 230 V powered can extend the RF range via their meshing capability.

For more information see Zigbee^® network principle.

The maximum point-to-point RF range of the connected switch to a Zigbee^®receiver depends on:

Materials and obstructions

Radio waves can be attenuated by materials inside a building or room.


Wood, plaster, uncoated, without metal	Brick, concrete	Ferroconcrete, lightweight hollow walls filled with insulating wool on metal foil, metallic heating insulation sheets, metallic surfaces, glass with a metal coating, floor heating systems, metal faceplates	Confined metal space
Loss: 5-20%	Loss: 20-40%	Loss: 40-90%	Loss: 90-100%

A human body can obstruct the Zigbee^® radio path since its operating frequency band (2.4 GHz) resonates well with water particles. The Zigbee^® meshing capability will generally remain intact after a radio path distortion, but take caution when a lot of people, or an object containing large volumes of water (e.g. an aquarium), are located in a room.

Position

Plan the physical installation so that one Zigbee^® device is within the RF range of another Zigbee^® device. Start from the location of the master node (the wireless smart hub or wireless bridge) and place the nearest Zigbee^® device at max. 10 m.

Battery-powered or energy-harvesting Zigbee^® devices do not operate as repeating nodes in a Zigbee^® They only act as receiver nodes and can thus not be used to extend the network. Only 230 V powered Zigbee devices can function as Zigbee^® repeating nodes and support the meshing capability to extend the RF range.
Bear in mind the impact of materials on the RF range.

Avoid installing the Zigbee^®device:

In a narrow room with thick walls,
On the same wall as another Zigbee^®repeating or receiving node,
Close to the ground (the recommended mounting height is 105 - 120 cm above the final floor level),
On a metal or moist surface or in a damp environment, or
In so-called 'dead spots', caused by radio reflections from nearby conductive materials or obstacles such as, metal cupboards, doors with a metallic foil or items containing water (e.g. aquariums).

Sources of interference

A Zigbee^® connected switch is generally not disrupted by low-power electronic devices (e.g. DECT telephones, smartphones, WLAN routers, analogue radios, electronic ballasts, controllers, TVs, videos, computers, remote controls), and vice versa. Zigbee^® is a robust and reliable RF technology thanks to its meshing capability and ability to capture radio telegrams from noisy environments.
Mind that a high-power electronic device in a room may interfere with the radio telegrams of a wireless battery-powered Zigbee^®switch. Should this occur, identify the interfering source and remove it. If removal is not possible, consider relocating the switch or adding a Zigbee^® repeating node (e.g. connected switching socket outlet, Zigbee® (170-3xx05) or another 230 V powered Niko Zigbee^® device).

Installation of the flush-mounting box

Installation on a flush-mounting box is possible if the fourfold wireless battery-powered Zigbee^® switch (552-72014) is used with a metal base (552-720X0). The metal base contains a plastic cover to protect a person from touching live electric wires, should they be present inside the flush-mounting box. Make sure to install the flush-mounting box before mounting the fourfold wireless battery-powered Zigbee^® switch.

The dimensions of a flush-mounting box (pattress) for a fourfold wireless battery-powered Zigbee® switch are listed in the table below:

Ref.	Description	Value
A	Depth	min. 40 mm
B	Distance for screw fixing	60 mm
C	Inner diameter/width of a round or square box	± 60 mm
D	Multifold flush-mounting box centre distance horizontal	71 mm
E	Multifold flush-mounting box centre distance vertical	71 mm use article number 552-72014 + 552-72010 or 552-72030
F	Multifold flush-mounting box centre distance vertical	60 mm for BE and FR use article number 552-72014 + 552-72000 or 552-72020

It is not possible to install the fourfold wireless battery-powered Zigbee^® switch in a Niko splashproof (Hydro range) mounting box
The recommended mounting height is 105 – 120 cm, measured from the final floor level

Installation of the fourfold wireless battery-powered Zigbee^®switch

The fourfold wireless battery-powered Zigbee^® switch can be installed against a flat wall or on a flush-mounting box.

To install the fourfold wireless battery-powered Zigbee^®switch, proceed as follows:

Step	Action
	Slide the CR2450 coin cell battery into the rear side opening of the switch.
	Hinge the two central plates in the correct position.
	Install the switch at a recommended height of 105-120 cm above the final floor level. Use double-sided adhesive tape (included) or screws (excluded) to mount the base against a flat wall. Mind the UP arrow, which should be pointed upwards. Only use flat screw heads and apply hand force on the screwdriver when tightening the screws. Use a metal base when installing the switch on a flush-mounting box. Depending on the selected mechanical variant, secure the base with screws or clamps, .
	Fit the fourfold wireless battery-powered Zigbee® switch into the base by inserting the bottom part first, then the top.
	Attach the faceplate in the desired design and colour. Note that the recess should be pointing to the bottom.
	Press the faceplate evenly until a click is heard.
