1 About this document
This Installation Manual describes the system architecture and how to plan a wireless system application based on the Bewator Entro Access Control system
and the door unit RF Codoor (e.g. RF30-EM). Optionally the RF9 router can be
used for increasing distances.
The document is a complement to the Bewator Entro manuals and separate instructions for the hardware components.

3.1 General
The wireless concept is designed to minimize the installation efforts when applying security products to internal doors located in offices, schools etc.
By using electro-mechanical locking devices (RF30-EM) in the door environment,
the wireless concept eliminates the need for cables from the host system to the
door.
3.2 System Components
In a wireless application we currently use mainly three components:
– SR35i, the Bewator Entro Access Control Segment controller.
System description
– RF30-EM, the door locking device.
– RF9, the optional router.

3.2.1 SR35i Segment Controller
A working copy of the access control database is stored in the SR35i Segment
Controller, complete with all cardholders and their access rights. This unit is thus
able to enable or disable any access attempt at any door that it is connected to.
The SR35i can manage both wired doors (via RS485) and wireless doors (via radio).
Each Bewator Entro system can contain up to sixteen SR35i controllers.
3.2.2 RF9 Wireless router
The RF9 router is used to route and amplify the radio signal. This makes it possible
to increase the wireless connection distances. Note that the RF9 needs an exter-
nal power supply.
The RF9 also buffers messages and thus increases system performance.
3.2.3 RF30-EM Codoor
The RF30-EM is based on the well accepted Codoor unit which is mounted directly
on an existing mechanical door lock. It provides a card reader, key pad and lock
control. The unit is powered by two 9V lithium batteries. For a safe function we
strongly recommend the use of our Lithium batteries with 9V, 1200 mAh and sustaining minimum 400 mA peak current.
The unit provides not only wireless connection to an Entro system but also standalone functionality.
It also includes a PIR sensor which senses a person approaching the door. Until
the sensor is triggered, the RF30-EM saves battery life by switching off its other
features. The direction of the sensor may be adjusted to suit special cases.
By default RF30-EM is configured for stand-alone use but can very easily be reconfigured for system use.
Note: Do not mount two RF30-EM units back to back on one door. They cannot
both control the lock.
3.2.4 Bewator Entro software
Software installed in the PC is used for configuring both the database in the SR35i
and the wireless network.
Note that the access control system operates independently while the PC is shut
down.

3.4 Wireless network – important concept
3.4.1 Segment ID
The Segment ID consists of four digits.
Every SR35i is identified by a unique four-digit number known as the Segment ID.
All wireless units related to this particular controller are configured with its Segment
ID.
As soon as an RF9 or RF30-EM is configured with the same Segment ID as the
SR35i it strives to communicate with that unit.
Note that in some proprietary systems using Zigbee wireless technology the expression PAN-ID (Private Area Network Identifier) is used for Segment ID. This
wireless technology is known as Zigbee (IEEE 802.15.4).
The Segment ID must not be the same as a PAN ID in another Zigbee system
nearby.
3.4.2 Address
Every unit in a Bewator Entro network must be identified by a unit address. Each
unit address is visible in the Bewator Entro software.
Each SR35i segment controller is shown as Cxx, where xx is its address. Each
RF9 or RF30-EM is shown as Cxx:Wyy (or Cxx:Ry) where xx is the address of its
SR35i and yy is the address of the wireless unit.
3.4.3 Encryption and replay protection
The Installation key, which is found in the SR35i, is the base for encrypting the
wireless communication.
There is also an integrated replay protection that eliminates any attempt to manipulate the doors.
3.4.4 Routing
All units connected to a wireless segment always “strive” to reach the highest level
– that is the SR35i. If this fails a RF9 will be used for forwarding the information (to
SR35i).
Up to four RF9 routers can form a communication chain between a SR35i and an
RF30-EM. Thus a message from the segment controller is allowed to “jump” a
maximum of five times before reaching a door unit.

3.4.5 Signal strength
Service Mode
mode
25 m (free air)
Service Mode
25 m (free air)
Radio waves from any source spread out and thus become weaker with distance
from the source. Each Bewator Entro RF unit displays the strength or weakness of
the received wireless signals.
The RF30-EM shows the signal strength with the help of LEDs. The RF9 shows the
strength of the signal from the controller or intervening router with the help of
LEDs. The SR35i can display the received signal strength. The Entro software can
display the signal strength at SR35i controllers and at RF9 routers.

3.4.6 Quality of communication
Electromagnetic interference can degrade signal quality so that messages have to
be repeated.
3.4.7 Attenuation, absorption and reflection
All radio based systems are influenced by attenuation and absorption as well as reflection of the radio signal. More information is provided in Appendix A.
3.4.8 RF30-EM Service Mode
RF30-EM has an integrated Service Mode that makes the installation easier. LEDs
indicate the signal strength and quality. Most problems can be solved by adding
RF9 routers to the system as described in the RF9 configuration manual.

4 Planning a wireless application
Good planning is particularly necessary for a successful wireless installation. This
section describes what to consider before the installation is started.
Read Appendix A regarding considerations for RF communication.
If hard-wired door equipment is included in the site this should be installed and
tested first. You will then have a PC available with software for checking wireless
units.
Then follow section 8 Installation to see how the practical configuration is performed.
4.1 Noise
It is advisable to try to identify in advance any noise sources that will degrade the
radio signal. Bewator Entro wireless networks use the ZigBee radio technology so
take care if other ZigBee services are installed nearby. Other sources of interference include:
Wireless computer networks (WLAN) may interfere and the frequencies for this
and the SR35i must be investigated and adjusted.
Motors, high voltage equipment or microwave equipment may interfere. Do not
mount any wireless units near these.
Avoid mounting routers in kitchens or similar because microwave ovens will in-
terfere.
Metal will attenuate but also reflect the signal.
Thick concrete structures usually include steel reinforcement bars which absorb
and scatter the signal.
Human beings also absorb and reflect the radio signal. If you hold a unit its sig-
nal will change.
Planning a wireless application
4.2 Networking guidelines
4.2.1 Frequency analyzers (sniffers)
Wireless units operate in up to 15 frequency channels (11-26) in the frequency
band 2.405 to 2.480 GHz. The SR35i may be set to avoid channels used for other
services. The most likely sources of interference in the 2.4 GHz band are wireless
Ethernet networks (Wi-Fi/802.11), Bluetooth or other systems based on ZigBee.
Take advice on channel selection from your IT manager.
A wireless unit should not be installed less than one metre from a WLAN access
point using the same frequency channel or less than 10 metre from a 3G/UTMS
base station (e g in a shopping centre or similar).
Third party products are available i e frequency analyzers, sniffers, enabling a PC
to be used as a simple tool to scan for activity on the same or adjacent actual network frequency band(s).
