1. Description

iO-LORA wireless expanders with RF-LORA transceiver increase the number of inputs and outputs of the "FLEXi" SP3 control panel using two-way RF communication.

Compatible with the SP3 security control panel, GATOR Cellular and GATOR WiFi gate & door access controllers. Temperature sensor (1 pcs.) and readers of contact ("iButton") keys can be connected to the iO-LORA expander. The PGM output (relay) of the expander can be remotely controlled (on/off) by various electrical devices. iO-LORA has one digital input.

1.1 Features

Communication:

  • Line-of-sight wireless range up to 5000 m.

  • Up to 8 iO-LORA wireless expanders can be connected to the "FLEXi" SP3 control panel.

  • Products from HW iO-LO_x30x_7_230418 version come with a standard antenna suitable for most applications. In cases where it is necessary to provide high-quality communication at the maximum possible distance, an antenna (AX-ANT-KIT – 433 MHz, AX-ANT01S SF – 868 MHz) with a higher radio signal gain should be used.

Inputs and outputs:

  • Bus "1-Wire" is intended for connection of temperature sensor (1 pcs.) and readers of contact ("iButton") keys.

  • 1 input, of selectable type: NC, NO.

  • 1 output (relay).

Connection: - The iO-LORA wireless expander is connected to the "FLEXi" SP3 control panel via the RF-LORA transceiver.

  4. "SW2" button for linking the device and checking the connection.
  5. DIP switch "SW1".

DIP switch 'SW1' settings

For product HW iO-LO_x30x_7_230418 version:

  1. Radio frequency (OFF - RF1; ON - RF2). Intended for changing the radio channel if the current channel is heavily loaded.
  2. Modulation type (OFF - fast; ON - slow). The ON position allows you to increase the communication distance by about 2 times (depending on the environmental conditions). But if a quality connection is ensured using the OFF position, it is recommended to use it. In the ON position, system performance decreases.

NOTE: In iO-LORA and RF-LORA devices, the positions of the SW1 switch must match! Otherwise, the radio communication will not work!

2. Wiring schematics

2.1 Fastening

  1. Remove the top lid.

Two drawings showing how to remove the iO-LORA top lid. Left: insert a screwdriver into the slot at the top edge. Right: press the screwdriver handle downward to release the lid.

  1. Remove the PCB board.

  2. Fasten the base of the case in the desired place using screws.

  3. Reinsert the board.

  4. Close the top lid.

Drawing of the iO-LORA case: the right view shows the base and its mounting holes; the left view shows the PCB at the case edge, with a circled retaining point and an arrow pointing outward.

2.2 Schematic for connecting the power supply

Wiring diagram: power supply to iO-LORA. Power supply: +12V to +DC, 0V to -DC; the supply is labelled +12 V.

2.3 Schematic for connecting input

iO-LORA has one input. Input type can be set: NC, NO.

Normally open (NO) input circuit: the open NO contact is between IN and COM.
Normally closed (NC) input circuit: the closed NC contact is between IN and COM.

2.4 Schematic for connecting a temperature sensor

Temperature sensors should be connected according to the given schematic. Maxim®/Dallas® DS18S20, DS18B20 temperature sensor (1 pcs.) can be connected to the iO-LORA wireless expander. If a wire longer than 0,5 meters is used to connect a temperature sensor, we recommend using twisted pair cable (UTP4x2x0,5 or STP4x2x0,5). The „+5V” terminal on the board is for supplying devices connected to the "1-Wire" data bus with 5 V DC voltage.

Wiring diagram: iO-LORA to DS18B20 temperature sensor. Red wire: +5V to +Vdd. Yellow wire: 1 Wire to DQ. Black wire: C to GND.

The maximum output current is 0,2 A. The output is protected from overload. If the maximum allowed current is exceeded, the power will automatically be switched off. The "FLEXi" SP3 control panel automatically recognizes and links connected temperature sensor.

2.5 Schematics for connecting CZ-Dallas reader

The CZ-Dallas iButton key reader connects to the iO-LORA using the "1 Wire" data bus. The length of the wires connecting to the data bus can be up to 30 m.

Wiring diagram: iO-LORA to CZ-Dallas reader. Power supply: 12-26V + to +DC, - to -DC. Reader: white wire from 1-Wire to reader; gray wire from COM to reader, joined to yellow LED- wire. C joins +DC; NO feeds RED LED+ through a 1k resistor and NC feeds Green LED+ through a 1k resistor. The green and brown LED wires are labelled. 1-Wire connection up to 30 m. Set xOUT to 'System State': alarm on shows red, alarm off shows green.

2.6 Schematics for connecting iO-LORA modules

Wiring diagram: SP3 to RF-LORA, then wirelessly to iO-LORA modules 1 through 8, up to 5000 m. SP3 AUX+ (+12 V) to RF-LORA +DC, AUX- to -DC, 485 A to A RS 485, 485 B to B RS485. Module 1: 12-26V to +DC and -DC; +5V, 1-Wire and COM to temperature sensor Vdd+, DQ and GND (DS18B20 or DS18S20). Module 8: 12-26V to +DC and -DC; 1-Wire to CZ-Dallas reader white wire, COM to gray and yellow LED- wires; C joins +DC, NO feeds RED LED+ through 1k, and NC feeds Green LED+ through 1k. Reader 1-Wire connection up to 30 m; set xOUT to 'System State' for red when alarm is on and green when off.

Note

An RF-LORA transceiver must be connected to the "FLEXi" SP3 control panel and then up to 8 pcs. can be connected iO-LORA wireless expanders. It is recommended to use a twisted pair cable (UTP4x2x0.5 or STP4x2x0.5) to connect the temperature sensor. CZ-Dallas iButton key readers and temperature sensor must be connected to the "1-Wire" bus.
