2.4GHz RF Transceiver Module
Figure 1: 2.4GHz WRZ Radio Module
Note: This WRZ Radio 2.4G RF Module is designed to be used internally only in Johnson
Controls products. It is not intended to be sold as an end item by itself to external customers.
The Johnson Controls WRZ Radio 2.4G RF Module is a single printed wiring board that implements a self
contained, complete wireless interface module. The radio section utilizes Texas Instruments CC2530 radio
chip, following the 802.15.4 standard and is driven by a 32.000 MHz crystal circuit on board. The CC2530
chip drives a balun which couples the signal to an RF amplifier delivering 10 mW to either an internal F
antenna or external antenna through a MMCX connector to the approved antenna.
The RF power output for the transmit amplifier is limited to 10 dBm. The RF Module is designed to be
mounted in various plastic enclosures depending on the requirements of the product and interface protocol.
The RF Module is a completely self contained radio module which has its own RF shielding. No other RF
shielding is required or implemented. It modulates its own RF transmitter. It controls the data flow to the
transmitter section compliant with FCC Part 15 requirements. The module uses ZigBee channels 11 -26 in
the 2450 MHz band.

Model Number and Description
MODEL NUMBER DESCRIPTION
25-2845 Internal circuit board trace antenna or external antenna as defined by
the board assembly options.
Power Requirements:
There is not a hardware voltage regulator on board. The unit operates within the stated FCC part 15 requirements
when operated within the specified supply voltage range of 2.3VDC to 3.6VDC (3.0VDC nominal). The unit will not
transmit if the supply voltage exceeds the maximum. Current drain is approximately 50mA during transmission, 35mA
when receiving, and 5 micro-Amps with the radio off in sleep mode.
Connection to Motherboard:
The Radio Module is intended to connect to a motherboard using 24, surface to surface solder pads. This interface is
for the 3.0 VDC power source and all necessary data lines to communicate with the radio module. The pins can be
configured for various serial data and general purpose input/output functions.

FCC and Industry Canada:
The JCI user manual for the end product that has this radio module integrated in to it must include
the following information in a prominent location:
“To comply with FCC and Industry Canada RF radiation exposure limits for general population, the
antenna(s) used for this transmitter must be installed such that a minimum separation distance of 20cm
is maintained between the radiator (antenna) and all persons at all times and must not be co-located or
operating in conjunction with any other antenna or transmitter.”
The manual must also not provide information regarding how to install or remove this RF module or change RF
related parameters.
The Johnson Controls WRZ Radio 2.4G RF module has been certified for integration into products only by OEM
integrators under the following conditions:
1) The antenna must be installed such that a minimum separation distance of 20 cm is maintained between the
radiator (antenna) and all persons at all times.
2) The transmitter module must not be co-located or operating in conjunction with any other antenna or
transmitter.
As long as the two conditions above are met, further transmitter testing will not be required. However, the OEM
integrator (JCI only) is still responsible for testing their end-product for any additional compliance requirements
required with this module installed (for example, digital device emissions).
IMPORTANT NOTE: In the event that these conditions cannot be met (for certain configurations or co-location with
another transmitter), then the FCC and Industry Canada authorizations are no longer considered valid and the FCC
ID and IC Certification Number cannot be used on the final product. In these circumstances, the OEM integrator
(JCI) will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC
and Industry Canada authorization.
END PRODUCT LABELING
The WRZ Radio 2.4G RF Module is labeled with its own FCC ID and IC Certification Number. If the FCC ID and IC
Certification Number are not visible when the module is installed inside another device, then the outside of the
device into which the module is installed must also display a label referring to the enclosed module. In that case, the
final end product must be labeled in a visible area with the following:
“Contains Transmitter Module FCC ID:OEJ-WRZRADIO”
“Contains Transmitter Module IC: 279A-WRZRADIO
Or
“Contains FCC ID: OEJ-WRZRADIO”
“Contains IC: 279A-WRZRADIO”
The WRZ Radio 2.4G RF Module must only use the approved antenna(s) listed in this document, which have been
certified with this module.

This radio transmitter has been approved by Industry Canada to operate with the antenna type listed below
with the maximum permissible gain and required antenna impedance for the antenna type indicated.
Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type,
are strictly prohibited for use with this device.
This device has been designed to operate with the antenna listed below and having a maximum gain of 2
dBi. Antennas not included in this list or having a gain greater than 2 dBi are strictly prohibited for use with
this device. The required antenna impedance is 50 ohms.

les risques de brouillage radioélectrique à l'intention des autres utilisateurs, il faut choisir le type d'antenne et son
gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne dépasse pas l'intensité nécessaire à
l'établissement d'une communication satisfaisante.
Le présent émetteur radio IC a été approuvé par Industrie Canada pour fonctionner avec les types d'antenne
énumérés ci-dessous et ayant un gain admissible maximal et l'impédance requise pour chaque type d'antenne. Les
types d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal indiqué, sont strictement
interdits pour l'exploitation de l'émetteur.
Cet appareil a été conçu pour fonctionner avec les antenne énumérés ci-dessous et d'un gain maximum de 2 dBi.
L'utilisation d'une antenne autre ou d'un gain supérieur est strictement interdite. L'impédance d'antenne requise est
de 50 ohms.
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence.
L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2)
l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le fonctionnement.
