1. 

Activate the locking mechanism if the detector is to be locked into the 
base. To do this, remove the small portion of plastic shown in 

Fig 1

 with 

side cutters or similar tool.

2. 

Partially screw two screws into the mounting box or soffi t at the required 
centres. Place the corresponding slots of the base over the screws and 
slide the base home.  Tighten up the screws.

3. 

Fig 1

 shows the wiring terminals.  The terminal marked ‘4’ on the base 

is provided for con-
necting the screen 
or functional earth.

4. The 

outside 

of 

the 

base is marked with 
a moulded vertical 
line  to  indicate  the 
position of the LED 
when the detector 
has been fi tted.  This 
facilitates detector
