7 Check rear tamper
8 Fix back box
Offer the back box to the wall.
Ensure that the rear tamper switch
operates. If necessary, remove the unit
from the wall and carefully adjust the
microswitch arm.
All four circled
positions must
be used, to
ensure a firm
fixing.
9 Back box connection wiring
All external connections should now be made within the back box.
Iris+ must NOT be used as a junction box or cable termination point as this will
adversely effect the performance of the system.
The Iris+ case must be earthed. A separate earthing tag is provided and is shown above.
The Iris+ requires a 12Vdc supply. The 0v line must NOT be connected to the same point
as the case earth.
Note: details of other back box connections, can be seen on pages 13 & 14.
