Technical Overview Installation
The site survey receiver is used in conjunction with the Son-
tay®RF-PS522 site survey routers, RF-HHT hand-held
monitor and RF-TS911 nodes, which form a site survey kit
(SSK).
Routers are used to route signals from battery powered
nodes and other routers to the receiver module, where the
signal strength of a direct path is not sufficient for reliable
communications.
Data is transmitted back to the receiver at configurable time
intervals, or on a configurable change in measured value.
Each sensor retains these configurations if the battery be-
comes discharged or requires replacement.
The SSK receiver automatically selects which of the 16
transmission channels available gives the best radio network
performance, taking into account both signal strength and
interference levels from adjacent channels and equipment
(such as Wi-Fi etc.)
The SSK hand-held monitor, nodes and routers automatically
find the best path back to the receiver, which may be direct-
ly to the receiver or via “parent” routers.
NB Unlike an RF-RX20 or RF-RX40 system receiver, the
SSK receiver has no analogue outputs.
Power
The SSK receiver uses an internal 12Vdc NiMH battery. Ob-
serve power connections polarity.
1. Remove all packaging from the SSK receiver
2. Note the MAC address printed on the affixed label.
3. Mount the SSK receiver in the same position as the
system receiver will be mounted during the final
installation.
4. Ensure the antenna is positioned in a vertical align-
ment.
5. Ensure that the internal battery is fully charged.
6. To power the SSK receiver, turn the On/Off switch
on the housing cover so that it points downwards
towards the charging socket. To switch off, turn the
On/Off switch on the housing cover so that it points
upwards away from the charging socket.
Battery Charging
To charge the battery in an SSK receiver, connect the cor-
rect charger to the socket mounted underneath the On/Off
switch. The status LED on the charger will show red until the
battery is fully charged, when the status LED will turn green.
Note that when charging SSK batteries, the battery under
charge is disconnected from the rest of the device, and
therefore that device will not function until charging is com-
plete.
Battery Fitting and Replacement
NB It is recommended that only suitably trained personnel
are used to replace the battery in the SSK receiver. A special
tool is required to disassemble the case and the battery
requires soldering.
When a battery is replaced, observe the correct polarity.
Fitting the battery incorrectly may result in perma-
nent damage to the sensor.
The case of the SSK receiver must be disassembled to gain
access to the internal battery.
NB NiMH batteries are rechargeable, but care must be taken to use ONLY THE
CHARGER SUPPLIED IN THE SSK BY SONTAY.Replacements or spares
should be stored in a clean, cool (not exceeding +30°C), dry and ventilated
area.
Disposal of Batteries - Warning! Fire, Explosion and Burn Hazard.
Do not short-circuit, crush, disassemble, heat above 100°C (212°F), incinerate,
or expose the battery contents to water. Do not solder directly to the cell.
All batteries must be disposed of in accordance with EC Directive 2006/66/EC,
amended by EU Directive 2008/12/EC.
