1. GENERAL 

DESCRIPTION 

In the photocell FT25B the transmitter can be powered with two 3.6V 2.7Ah Lithium-Tionyle Chloride batteries or with an external power 
supply at 12-24 VACDC, selectable with a jumper. 
The photocell has two terminals in which the output contact of a safety device (e.g. a rubber edge) can be connected, and it is 
particularly suitable to be used in sliding gates, mounted on the moving wing, allowing to connect the edge safety device without long 
cables or self-winding cables. 
Battery life is more than 15 months. 
The photocell is manufactured in compliance with the European directive 98/336/EEC (EMC). 

 

2. APPLICATIONS 

In sliding gates or other kinds of installations where cables cannot be used or must be reduced (e.g. in existing installations where a 
safety device must be added)

6. INSTALLATION 

Mount the photocell by using the supplied templates (fig.2) 

Connect the wires as described in paragraphs 4 and 5 and select the source of power supply with the relevant jumper (J2, fig 1B): 

POSITION A: external power supply 12-24 VAC/DC 
POSITION B: battery 

Connect the output contact of the safety edge (or other safety devices) to the relevant terminals (J1, fig. 1B). If this option is not 
used, don’t remove the existing short-circuit. 

Align the beam with the receiver using the relevant adjustment screws “A” (fig. 2) on the receiver and transmitter. 

Measure with a voltmeter the voltage at the receiver test-points (fig.3). This value varies in accordance with various parameters, 
among which the distance between the photocells. The higher the voltage value at the test-points, the better the alignment. 
Optimum voltage should be between 0,5 and 0,6 VDC. 

Interruption of the infrared beam generates opening of the  normally closed contact of the relay on the receiver and lighting up of 
the red LED.
