RFSF-1B Level Switch
**User Manual

**

Characteristics

• Monitors areas (e.g. bathrooms, basements, shafts or tanks) to provide flood warning.

• Upon detecting water, the flood detector immediately sends a signal to the switched unit, which further switches on a pump, GSM gate (RFGSM-220M) or closes a pipe valve.

• Option of connecting an external probe FP-1 (not included in supply – max. wire length 30 m.

• The programming button on the detector is used to:
  a) setting the function with switching unit.
  b) ascertaining battery status.
  c) ascertaining signal quality between the unit and detector.

• Battery power supply (3V/CR2477 – included in the supply) with battery life of around 1 year based on frequency of use.

•  The detector can be placed anywhere thanks to battery power.

• Range up to 160 m (in open space); if the signal is insufficient between the controller and unit, use the signal repeater RFRP-20 or protocol component RFIO2 that support this feature.

• Communication frequency with bidirectional protocol iNELS RF Control.

Control options

• the wireless flood detector RFSF-1B can control switching units e.g.: RFSA-11B/61B/62B, RFSA-61M/66M, RFSAI-61B, RFSC-11/61, RFUS-11/61
• option of control via RFRP- 20

Assembly

Radio frequency signal penetration through various construction materials

Indication

• LED STATUS – indication of the device status.
• Terminal INPUT – for controlling the level probe.
• Communication with programmed unit is performed by pressing PROG for less than 1s.
• Jumper Function – function setting:
  – inserted jumper Function – immediate reaction to flood and to drainage.
  – non-inserted jumper Function – immediate reaction to flooding, during drainage the switching actuator remains closed until you press the Prog RFSF- 1B.

Programming with RF switching actuators

Using a screwdriver, carefully remove the rear cover.

Remove the device from the box.

While pressing Prog on the RFSF-1B, insert the battery. Observe the polarity. This activates the programming mode.
The red LED fl ashes in an interval of 2 fl ashes per second. After inserting the battery, release the button. Press the programming button and hold down until the LED fl ashes once per second. Then release the button. Pressing Prog < 1s on the assigned switching unit (must be connected to the power supply) sends a signal. The RFSF-1B indicates signal receipt by a red LED that lights up
for 1s.

Press of programming button on actuator RFSF1B shorter then 1 second will finish programming mode.

After fi nished programming, insert the device into the box and snap on the rear cover.

Note: if necessary you can program another switching unit – see Programming 1-5. By programming a new switching unit, you erase the previous settings

Programming with the RF switching unit with communication via RFRP-20

Steps 1-3 are the same as Programming the RF switching unit (see above).

Press the programming button and hold down until the LED fl ashes 3x per second.Then release the button. Steps 5-7 are the same as Programming the RF switching unit (see above). When inserting the RFRP-20 into an electrical socket (upon power-up), the programming button must be pressed. The green LED fl ashes. Then when the red LED button
illuminates, release the button. By one short press of the programming button on the RFRP-20, you move to the position for input into the additional learning mode. The red LED fl ashes – after 5s the RFRP-20 enters the additional learning mode. The LED stops fl ashing.

By pressing Prog on the RFSF-1B for less than a second, the signal is sent.
A fl ashing green LED on the RFRP-20 indicates that the RFSF-1B has been recorded in the memory. End learning mode by a short press of the programming button on the RFRP-20. By doing so, the programmed RFSF-1B address is stored in the memory. The red LED will
fl ash for 1 second, then the green LED will remain illuminated. After fi nished programming, insert the device into the box and snap on the rear cover.

Programming with the RF control unit RF Touch

An address listed on the front of the actuator is used for programming and controlling a temperature actuator by RF Touch.

Steps 1-3 are the same as Programming the RF switching unit (see above).

Press of programming button on actuator RFSF-1B shorter then 1 second will fi nish programming mode.

On the RF system unit, the address of the RFSF-1B is entered (see the manual of the RF system unit).

After fi nished programming, insert the device into the box and snap on the rear cover.

Function

After pressing the Prog button < 1s, the RFSF-1B communicates with the programmed unit and then indicates the battery status and successful connection to the programmed unit.
Indicating the battery status
After terminating communication, the red LED fl ashes according to the battery status:

• 1x – battery OK.
• 2x – weak battery.
• Indication of successful connection

If an RF switching unit is programmed to the RFSF-1B, 2 seconds after battery indication, successful connection is indicated.

• LED fl ashes 1x – connection OK.
• LED fl ashes 2x – cannot connect to programmed switching unit.
  Note : Connection with RF Touch RFSF-1B is not indicated.

Replacement of a battery

Using a screwdriver, carefully remove the rear cover. Remove the device from the box.

Remove the old battery from the battery holder.

Slide a new battery CR2477 battery into the battery holder. Observe the polarity.
After inserting the battery, the number of LED fl ashes indicates:

• flashes 1x per second – programmed with switching unit.
• flashes 2x per second – programmed with RF Touch.
• flashes 3x per second – programmed with switching unit via RFRP-20.

Insert the device into the box.
Snap on the rear cover.

Safe handling

When handling a device unboxed it is important to avoid contact with liquids. Never place the device on the conductive pads or objects, avoid unnecessary contact with the components of the device.

Additional information

Error conditions

button on the product, perform communications test with battery measurement, if the LED indicates a drained battery or does not indicate anythina, change the battery.
The RFSF-1B does not control units – LED reports unsuccessful communication.| Problem with range of radio frequency signal.| The actuator was probably installed at the edge of problem-free range or surrounding conditions changed, ex. installation of a WiFi network in close proximity, barrier in front of the unit, etc. Removing fault by better installation of product.
The battery in the RFSF-1 B must be changed often, range test is OK.| Water has gotten into the product or it has been flooded for a lengthy period.| The product can become irreversibly damaged.

Attention:
When you instal iNELS RF Control system, you have to keep minimal distance 1 cm between each units.
Between the individual commands must be an interval of at least 1s.

Warning
Instruction manual is designated for mounting and also for user of the device. It is always a part of its packing. Installation and connection can be carried out only by a person with adequate professional qualifi cation upon understanding this instruction manual and functions of the device, and while observing all valid regulations. Trouble-free function of the device also depends on transportation, storing and handling. In case you notice any sign of damage, deformation, malfunction or missing part, do not install this device and return it to its seller. It is necessary to treat this product and its parts as electronic waste after its lifetime is terminated. Before starting installation, make sure  that all wires, connected parts or terminals are de-energized. While mounting and servicing observe safety regulations, norms, directives and professional, and export regulations for working with electrical devices. Do not touch parts of the device that are energized – life threat. Due to transmissivity of RF signal, observe correct location of RF components in a building where the installation is taking place. RF Control is designated only for mounting in interiors. Devices are not designated for installation into exteriors and humid spaces. The must not be installed into metal switchboards and into plastic switchboards with metal door – transmissivity of RF signal is then impossible. RF Control is not recommended for pulleys etc. – radiofrequency signal can be shielded by an obstruction, interfered, battery of the transceiver can get fl at etc. and thus disable remote control.
