RF / RF.SUN
DESCRIPTION
Radio-transmitter for sensitive safety edges, to be applied on movable closures, pursuant to EN 
12978 standard. 
This allows for the bi-directional communication via radio between the device on mobile edge 
and the SC.RF receiver mounted on the control unit. 
It is available in 2 versions (Fig. 1): 
1 RF*: Powered with two alkaline batteries, AA type. 
2 RF.SUN: It is powered with two NiMh batteries, recharged by solar panel SUN (Fig. 1 – ref. 3) 
to be installed on the movable closure. 
Both sensitive edges of the resistive type (8K2) and edges of the mechanical type can be used 
on both models with normally closed contact. 
OPERATION
A typical installation of the RF.SUN transmitter on the leaf of a sliding motor is shown in figure 
2. 
1 RF or RF SUN transmitter. The status of the sensitive edge is sent via radio to the SC.RF 
receiver. 
2 Sensitive safety edge of the resistive or mechanical type. 
3 The SUN solar panel provides for the recharging of the battery inside the RF.SUN device 
4 The SC.RF radio receiver sends information on the status of the sensitive edge to the control 
unit.
Note: SC.RF is provided with two separate communication channels, each of them is able to store up to 4 RF/RF.SUN devices. Therefore, up to eight sensitive safety edges can be mounted.
Each single transmitter requires a special learning proceeding to communicate with the receiver, by using the push-button S1 (Fig. 3), as indicated in the manual supplied with SC.RF.

REPLACEMENT OF THE BATTERY
After a certain period, more or less long according to conditions of use, alkaline batteries supplied with the RF device should be replaced. 
They can be replaced by standard AA alkaline batteries.
