SENSOR 2 CODE ( Programming for transceiver RTX
2252 Sensor no. 2)
To programme the transmission code for RTX 2252 (Sensor)
Transceiver no. 2 combined with an RTX 2278 (Base)
Transceiver, proceed as described in point "2) SENSOR 1
CODE".

If the device must be reset to factory configuration, keep the
SEL and SET keys simultaneously pressed down for more than
2 seconds so that all signal LEDs briefly switch on at the same
time accompanied by three quick Buzzer Beeps.

Description of Operation
The RTX 2252 (Sensor) device allows NC (normally closed
contact) standard type or 8K2 resistance type sensitive edges
to be connected, normally installed on the mobile part of the
gate.
It only works in combination with the control Base. The device is
battery-operated so as to exclude any type of cable connection.
Once it is memorised (see "RTX 2278 - Programming Keys and
Signal Leds" paragraph) it can send the following information to
the RTX 2278 (Base) device:
-
Survival signal:
this is used to periodically check the correct radio connection
between the devices.
-
Alarm signal:
this is used to inform the base that the safety device is
operating.
-
Low battery signal:
this is used to inform the system of the battery level.
ATTENTION! If the RTX 2252 Device (Sensor) is dismantled
from an installation, it is advisable to take the batteries out so
that the Sensor no longer continues unnecessary transmission.

NC or 8K2 Operating Mode Selection
The RTX 2252 Device allows NC (normally closed contact)
standard type or 8K2 resistance type sensitive edges to be
connected. Use Dip Switch SW2 No. 1 to make the selection:
DIP 1 = OFF NC input operation (default).
DIP 1 = ON 8K2 input operation.

NC 8K2
Transmission Mode Selection
With the RTX 2252 (Sensor) Transceiver device it is possible to
select two different operating modes, "Normal" or "Low Power".
The difference in operation consists in the Sensor transmitting
power. In "Low Power" operating mode the transmitting power
of the Sensor is considerably lower; in terms of energy savings,
which translates into longer battery life, it is necessary,
however, to take into account the subsequent reduction in radio
capacity for installation.
Use Dip Switch SW2 No. 2 to make the selection:
DIP 2 = OFF : "Low Power" operating mode disabled (default).
DIP 2 = ON : "Low Power" operating mode enabled.

LP=OFF LP=ON
Inhibitor Input Operating Mode
With the RTX 2252 (Sensor) Device it is possible to connect an
(NC) contact to temporarily inhibit the sensitive edge installed
on it.
ATTENTION! When not in use, the inhibitor input must always
be jumpered.
Low Battery Signal
Discharged battery levels are reported by the TX LED flashing
quickly on the RTX 2252 (Sensor) Device. The same
information is also sent to RTX 2278 (Base) device, that reports
the event with visual and acoustic warnings.
ATTENTION! We recommend replacing the device batteries as
soon as the TX LED starts flashing.
ATTENTION
- For best performance, change the 1.5V alkaline batteries
annually.
- To change the batteries, open the Sensor container with a
screwdriver.
