MOUNTING PROCEDURES: 
 
 

CAUTION:  Check that the installed product will have sufficient clearance and wiring 

room prior to installing backboxes and conduit, especially if sheathed multiconductor 
cable or 3/4" conduit fittings are used. 
 
 
  1.  NS4 models have an integrated NS Mounting Plate (NSMP). 
 
 
  2.  The NS Mounting Plate (NSMP) must be oriented correctly when it is mounted to the 

backbox.  Turn the NSMP so that the arrow below the word ‘‘Top’’ points to the top 
side of the NSMP. 

 
 
3  .  NS4 models can be flush mounted to a standard single-gang backbox (Figure A), 4”  or 

100mm backbox (Figure B) or double-gang backbox (Figure C).  NS4 models can also be 
surface mounted to a 4’’ or 100mm backbox (Figure B), double-gang backbox (Figure C) 
or the SHBB (Figure D). 

 
 
  4. Mount the NSMP first to the backbox.  Next slide the Beauty Plate over the NSMP 

until the 2 side snaps of the NS Beauty Plate engage with the NSMP. 

 
 
  5.  The NS Beauty Plate can be removed from the strobe assembly once engaged.  First, 

gently insert a screwdriver into one of the slots located on the side edges of the NS 
Beauty Plate.  Second, gently pull away from the wall with the inserted screwdriver to 
disengage the snap.  Third, repeat the first and second steps for the second slot.  
Finally, gently lift the Beauty Plate away from the NSMP. 

 
 
  6.  Mounting hardware for each mounting option is supplied. 
 
 
  7. Conduit entrances to the backbox should be selected to provide sufficient wiring 

clearance for the installed product. 

 
  8. When terminating field wires, do not use more lead length than required.  Excess 

lead length could result in insufficient wiring space for the signaling appliance. 

 
 
  9.  Use care and proper techniques to position the field wires in the backbox so that 

they use minimum space and produce minimum stress on the product.  This is especially 
important for stiff, heavy gauge wires and wires with thick insulation or sheathing. 

 
 
10. Do not pass additional wires (used for other than the signaling appliances) through 

the backbox.  Such additional wires could result in insufficient wiring space for the 
signaling appliance.
