Mesh network planning – easy and reliable

ASAtechnology – best protection without false alarms

Transmission distance on same floor

Three simple planning steps

Following these project planning rules eliminates the need for

on-site measurements and use of a tool:

– 1. Net size

•

Max. 30 network nodes per gateway

•

Max. 16 gateways per loop/stub

– 2. Max. transmission distance

•

Max. distance of 90 m between gateway and farthest detector

(with 3 hops).

– 3. Network density

•

Max. transmission distance between two network nodes is 30 m,

or 20 m respectively through one wall.

•

The more wireless devices a network has, the more paths are

possible, which increases the reliability of the network connection.

Transmission distance spanning 5 ﬂoors

– One gateway can cover up to 5 floors.

– To be in contact with the gateway, all wireless devices have to be

within transmission distance.

– Transmission distance from the gateway across up to 5 floors:

•

Floor +2: 20 m radius

• Floor +1: 40 m radius

• Within floor: 60 m radius

• Floor -1: 40 m radius

• Floor -2: 20 m radius

Please note

– The transmission distance of up to 30 m between two

network nodes applies for cases with a simple building

structure and where there are no walls between the nodes, e.g.

in a large hall. With 3 hops, this adds up to a total of

90 m between the gateway and the farthest detector.

– The transmission distance of up to 20 m between two net

work nodes applies for cases where there is a concrete wall or a

ceiling between the nodes. With 3 hops, this adds up to a total

of 60 m between the gateway and the farthest detector.

– In an area containing metal (e.g. an elevator shaft), glass

(e.g. a patio) or reinforced concrete wall or ceiling, it may also

be possible to plan a path around the obstacle (see example

“patio”).

– Optimally, the gateway is placed centrally, but away from

large metal objects.

– For detector positioning, local regulations may apply.

(1) The signals recorded by the

sensor are converted into math-

ematical components using

algorithms and compared with

preprogrammed values. With the

selection of an ASA parameter set,

the algorithms can be influenced –

and the fire detector can be set to

the expected local environmental

influences and individual risks. The

optimal parameter set is selected

taking the individual risks and the

existing environment into account.

The parameter sets can be selected

according to the application guide

line. In very difficult applications,

the data recorder from Siemens can

be used to measure the specific

challenge and select and document

the appropriate ASAtechnology

parameter set.

(2) + (3) Interpretation of the situation in real

time results in the selected ASA parameter set

being dynamically adapted. This automatically

shifts the optimum application range of the

detector. Consequently, the detector reacts more

sensitively in the event of a ﬁre – and more

forcefully in response to deceptive phenomena.

(4) The result is unique

ﬁre detection with unprec-

edented reliability against

deception.

Transmission distance spanning up to 5 floors

Mesh technology – as safe as cable

Yesterday: star technology

Today: mesh technology

Mesh technology – safe from disruptions Intelligent routingChange of channel or frequency band

Mesh technology basics Multi-hop and 2-path communication

Basic information about SWING mesh technology:

– Node:

•

Wireless device, e.g. SWING detector or SWING manual

call point

•

Each node has two frequency bands: 868 MHz SRD-band

(23 channels), 433 MHz-band (20 channels)

– Hop:

•

Link between two wireless devices

•

Up to 3 hops allowed between farthest node and gateway

•

2 hops = multi-hop

SWING mesh technology – an enormous leap from

traditional to innovative technology

The mesh technology allows for a safer connection than with

the traditional radio solution and is as redundant as the ring

main wiring (loop):

– Every SWING detector or manual call point acts as a network

node.

– Every network node communicates with two or more network

nodes.

– Information is transmitted from node to node until it reaches

the gateway (up to 3 hops).

– Therefore, not every node has to have a direct connection to

the SWING gateway.

Beneﬁts

– Stronger and more reliable connection than with traditional

1:1 connection of wireless detector and gateway.

–

Larger networks are possible:

• Up to 90 m from the gateway to the farthest network

node (detector) if there are no walls in between and with

max. 3 hops.

Safe as a loop – intelligent multi-hop communication

with two paths

The mesh technology offers the same safe connection as a loop:

– Up to 3 hops between gateway and farthest detectors.

– Each network node communicates with its neighbors.

– Use of multi-hops allows large and reliable transmission

distances throughout the whole system.

– At least two different paths (different hops and nodes) are always

possible to transmit information from one node to the gateway.

– Wireless devices connect and configure themselves –

continuous network adaptation during operation.

Network nodes check constantly whether two connections are

available – independent of an alarm. They continuously look for an

optimal connection. If one connection is lost, the network node will

automatically look for a possibility to maintain the connection or find

another path. Disruptions can be caused, for example, by other radio

systems, e.g. garage door opener, remote controls or EMC through

elevator drives.

In case of a disturbance, a network node dynamically changes:

1. Channels within frequency band

2. Frequency band if change of channel is not successful

3. Channels within new frequency band

In case a change of channel and of frequency band is not success

ful, information will be rerouted on the other path. The panel will

display the message “One path lost”. This message will disappear as

soon as the second redundant path is available again.
