General description

To ensure that a wireless fire detection system works correctly and to avoid installation issues, the use of the HFW-STK-03 is strongly recommended, as it is a proven test kit that enables the installer to check the wireless link quality on the installation site and
therefore choose the perfect position for the wireless devices.
The HFW-STK-03 is a “ready to use” diagnostic system; it’s easy to use and it doesn’t need a particular programming setup.
When the kit’s tablet is remotely connected to the HFW-EM-01 expander module through the Dongle interface device, the wireless link quality is shown on the tablet’s dedicated app.
The installer can easily move around the site with the tablet, the Dongle and the survey detector to check the quality signal level between the HFW-EM-01 and the survey detector (picture 1). kit’s content list

Technical specifications

Measure of the wireless link quality

Wireless link quality between devices can be measured using two indicators:
dB units
Simply decibel units.
RSSI units
RSSI is the acronym of “Radio Signal Strength Indicator” and it is obtained from the measure of the wireless signal quality (in dB units) and the noise level (still in dB units). In order to simplify the measurement of the wireless signal’s quality, RSSI and dB units are spaced out in five possible “mark” levels (table 1); on the tablet’s survey app, levels from Mark 5 to 2 are visualized using four different colours (picture 2); Mark 1 is considered as “no link”.

Table 1

In order to work properly, the devices must operate with a signal level quality in the Mark 5 (picture 2, green area) or Mark 4 (picture 2, yellow area) bands.
Mark 3 band is not recommended.
If the signal’s level quality is below Mark 3 (i.e. Mark 2), you must change the position of the devices (either the HFW-EM-01 or the survey probe detector).
If the HFW-EM-01 and the probe detector do not communicate, the survey app will show a warning popup.
You will notice that the signal’s value graph on the survey app is traced either in green or, sometimes, in orange:
Green colour indicates that the wireless signals are received on the HFW-EM-01 primary antenna.
Orange colour indicates that the wireless signals are received on the HFW- EM-01 secondary antenna.

Survey setup

HFW-EM-01 test expander

1. Place the HFW-EM-01 test expander in the exact location of the installation site where you want to install a wireless system central or relay node (i.e. HFW-W2W-01 wire to wireless translator, HFW-EM-01 wireless expander or a HFW-CEM-02 wireless conventional system expander module).
2. Connect the power supplier’s output to the HFW-EM-01; the socket for the connector is located on the top side of the HFW-EM-01 (picture
3. Connect the power supplier to the household mains line.

HFW-EM-01 is now ready for use.

Alternatively, you can connect the HFW-EM-01 test expander to a suita- ble power supply battery through the battery connector cable (picture 3b).
Battery’s suggested specifications are given at the beginning of this manual.

1. Place the HFW-EM-01 test expander in the exact location of the installation site where you want to install a wireless system central or relay node (i.e. HFW-W2W-01 wire to wireless translator, HFW-EM-01 wireless expander or a HFW-CEM-02 wireless conventional system expander module).
2. Connect the red wire push-on terminal to the battery’s positive pole.
3. Connect the white wire’s push-on terminal to the battery’s negative pole.
4. Insert the battery connector’s jack plug into the HFW-EM-01 power supply socket; this socket is located on the top side of the HFW-EM-01.

Survey detector

1. By rotating it clockwise, remove the survey detector from its support base (picture 4).
2. Extract the battery cover from the bottom of the detector.
3. Insert both CR123A batteries into their detector’s housing (picture 5). Batteries polarities must match the indicated polarity on the detector.
4. Wait until the LEDs at the top of the detector stop blinking.
5. Reinstall the detector’s battery cover.
6. Reinstall the detector on its base.

The survey detector is now ready for use.

Supporting pole

The supporting pole is used to enable the assessment of the wireless link quality in high locations.
It can be used, also, for assessing lower locations and areas for possible interference caused by wireless fading.

1. Assemble the pole as per picture 6.
2. Fix the survey detector probe at one end of the pole (picture 6).

Dongle interface device – battery power supply

1. Extract the battery cover from the back of the Dongle device.
2. Insert both LR6 AA batteries into their housing. Batteries polarities must match the indicated polarity on the device.
3. Reinsert the battery cover.
4. Switch on the Dongle device (On / Off switch on the device; check picture 8).
   Dongle’s LED performs some green-red blinking, then stops: the device is now powered on.

Dongle interface device – external power supply

– Connect the Dongle’s Micro USB with OTG cable (not supplied) port to the tablet’s Micro USB port (picture 9)
or
– connect the Dongle’s Micro USB port to the output of the tablet’s power adapter.
External power supply is useful in the event Dongle’s batteries run out.

Tablet

1. Long press the key on the side of the tablet (picture 10). Tablet’s “lockscreen” will appear.

   Tablet screen appears as follows:

2. Check that RFAnalyze and Survey icons are blue; if they are grey coloured, consult the troubleshooting section at the end of this manual.

3. Tap on one of the icons to start the needed app.

RFAnalyze
This tool is used to monitor wireless environmental traffic in one or more channels; purpose of this is to find a relatively clean channel suitable for your wireless system.
Interference that can be assessed with this app is normally caused by other wireless devices or other equipment operating within the monitored channel or channels.
Survey
This app is used to measure the wireless signal’s link quality between the test HFW-EM-01 and the survey probe.

RFAnalyze
Tap on the RFAnalyze icon to start the app.
The following window will appear:
Bear in mind that the analysis of the channel you are working on is strongly recommended in order to avoid possible problems during commissioning.
At the beginning, this window shows, through a graph, the degree of wireless traffic present in ALL channels; a single graph of one colour shows the traffic present in one single channel.
Since your system works in one channel only, it is possible to filter out those channels you are not interested in; to do this, on the right upper side of the window tap on the funnel-like icon (in picture 12 is highlighted with the circle).
The following selection window appears: 1. Select those channels that you want to be visualized. Deselect those channels that you don’t want to be visualized.
2. Tap on “SUBMIT”.

Survey
Tap on the Survey icon to start the app.
The following window will appear:

Select the device type you want the survey probe to simulate; bear in mind that different device types have different signal quality levels, so it is strongly recommended that you select the correct type.
The HFW-STK-03 system will now effectively simulate the selected device, in terms of wireless link quality.
Having selected the device type, the following window appears:

Wireless link quality measurement between the probe and the HFW-EM-01 is indicated on screen, and its temporal progression is tracked outwith a graph.
To achieve a stable progression level it is recommended to wait some minutes after placing the survey detector probe in the chosen position.
If you want to select another device type tap on the symbol to return to the device type selection screen.
To access Survey’s settings window tap on the icon.
The following window will appear:

In this window it is possible to:
– Check the wireless system code (Syscode); it cannot be changed.
– Check the frequency band; it cannot be changed.
– Check and modify the survey operating channel.

To change the survey operating channel:

1. Tap on the desired channel (picture 17).
2. Tap on “SUBMIT”.
3. Wait that the system performs the change of the working channel (picture 18).

This operation MUST be performed with the HFW-STK-03 perfectly operating and ALL its devices switched on.
Doing otherwise can compromise the function- ality of the HFW-STK-03 itself.
The following table gives the key to symbols that are used in the Survey app.
