- Work frequency
: 868 MHz FSK Band
- Range in free space
: 10÷20m max.
- Working temperature
: -10 ÷ 55°C
- Dimensions
: 120x80x50mm.
- Container

CN1 Terminal board connections:
1 : (NC) or 8K2 Safety device input
2 : (NC) or 8K2 Safety device input.
3 : Inhibitor Input (NC).
4 : Inhibitor Input (NC).
FUNCTIONING DESCRIPTION:
The RTX 2252 (Sensor) device enables connection of NC (normally closed contact) classic
type or 8K2 resistive type sensitive edges, normally found in the gate’s mobile part.
Only works coupled with the RTX 2251 control (Base). The device is battery powered to
exclude every type of cable connection.
Once memorised (see “RTX 2251 - Programming Keys and Indicator LED” paragraph) it can
send the following information to the RTX 2251 (Base) device:
S

:
used to periodically check the correct radio connection between the devices.

:
used to inform the Base device that the safety device is activated.

:
used to inform the Base of the battery state.
ATTENTION!
If one RTX 2252 (Sensor) is no more used, remove the batteries to avoid the
Device goes on transmitting.

FUNCTIONING MODE SELECTION
RTX 2252 device enables connection of NC (normally closed contact) classic type or 8K2
resistive type sensitive edges. Use n. 1 Dip Switch SW2 to select:
DIP 1 = OFF NC input (default).
DIP 1 = ON 8K2 input.

8K2
TRANSMISSION MODE SELECTION
The RTX 2252(Sensor) allows to select two different transmission modes, “normal” or
“ low power”. The difference between the two modes is the transmission power of the
Sensor. In “low power” mode the power is lower: the battery duration increase, but the
range is smaller; consider that when you make an installation.
Use n. 2 Dip Switch SW2 to select:
DIP 2 = OFF : “normal”(default).
DIP 2 = ON “low power” .
