6. 

Electrical connections 

 

Conform to current electrical installation norms. 

 

For the connections according to the diagrams in these instructions.  Use cable with a minimum section of 1,5 mm² 

 

Permissible length for connections between detector and solenoid valve: max. 

80 m

 

 

Use solenoid valve output to connect only valves with power absorption not exceeding 13W

 

 

Check that any electrical devices controlled by the relay, are suitable for the maximum capacity characteristics (see 
technical specifications). 

 

Detectors  must  be  connected  directly  to  the  electric  relay,  without  disconnectors  or  switches  between  them,  and 
must be powered permanently. 

7. 

Mounting 

 

Remove the cover by unscrewing the screws on the bottom using a screwdriver. 

 

Fix the base to the wall.  

 

Form the electrical connections as shown in the diagrams contained in this manual.   

 

Fit the cover again, and tighten the fixing screw.  Work carefully to avoid damaging the LEDs. 

 

 

Note: Do not touch the sensing element or the electronic circuit for any reason whatsoever. Any tampering 
may compromise correct functioning of the detector, as well as exposing people to a risk of electric shock.
