1. Description

iO-8-LORA wireless expanders with RF-LORA transceiver increase the number of inputs and outputs of the "FLEXi" SP3 security panel using two-way RF communication.

Compatible with the SP3 security control panel and GATOR Cellular gate & door access controller. The iO-8-LORA wireless expander has 8 I/O terminals, each of which can be set as an input (IN) or as an output (OUT).

1.1 Features

Communication:

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

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

  • Products from HW iO8_x5xx_7_230419 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: - 8 I/O terminals, each one can be set as an input (IN) or output (OUT). Input (IN) types: ATZ, EOL, NC, NO. Different value of resistors can be used in EOL and ATZ type circuits.

Connection:

  • The iO-8-LORA wireless expander is connected to the "FLEXi" SP3 control panel via the RF-LORA transceiver.

DIP switch 'SW2' settings

For product HW iO8_x5xx_7_230419 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 iO8-LORA and RF-LORA devices, the positions of the SW switch must match! Otherwise, the radio communication will not work!

2. Wiring schematics

2.1 Schematic for connecting the power supply

Wiring diagram: Power supply to iO-8-LORA. Power: +12V to +DC, 0V to -DC; the positive wire is labelled (+12 V).

2.2 Schematics for connecting inputs

There are 8 terminals IO1–IO8 (inputs) on the iO-8-LORA expander board for connecting sensor circuits. Any terminal can be set as an input and assigned zone attributes: circuit type (NO, NC, EOL, EOL_T, 3EOL, ATZ, ATZ_T); sensitivity to temporary circuit events; zone function (Delay, Instant, Instant Stay, Interior, Interior Stay, Fire, Keyswitch, 24_hour, Silent, Silent 24h).

Normaly open (NO) input circuit: an NO contact connects IOx to C when closed. No resistor is shown.
Normaly close (NC) input circuit: an NC contact connects IOx to C. No resistor is shown.
