4.  Remove the trim ring/dome assembly by pulling on the outside 
     of the trim ring.  The ring and dome are connected by three flat    
     springs, which press against the side of the housing and lock into 
     (3) cutouts.
5.  Run electrical cable and video leads into the housing through the 
     conduit knock-out.
6.  With the (3) support arms rotated to the inside, slide the housing
     into the pre-cut hole (Figure 1). 

CAMERAS     VOLTAGE           CURRENT       POWER
        1              24 VAC/VDC     102mA              2.5W
        2              24 VAC/VDC      210mA             5W
        3              24 VAC/VDC      331mA             7.9W
        4              24 VAC/VDC      487mA             10.9W

Use the formula below to select the correct power supply for 
cameras connected in parallel (positive to positive, negative to 
negative):

                                  Note: 202mA is camera plus power supply 

This chart shows the proper current needed for power supplies for 
Q-View™ cameras. Use Class 2 Power only. Input voltage must 
be 24 VAC/VDC.

7.  With the bottom flange pressed up against the ceiling, rotate the
     support arms to the outside, the arms will fall to the back side of
     the ceiling. Tighten the (3) support arm screws (Figure 2).

8.  If the housing is going into a ceiling where the support arms will
     not work, secure the housing by running bolts into the solid ceiling
     through the mounting holes in the bottom flange (Figure 1).
9.  For added support, run support wires from a secure structure to
     the two slots provided on the top of the housing (Figure 3).

1.  Carefully remove all equipment from the box.
2.  Place the 11 1/8" template provided with the unit at the desired 
     location on the ceiling. Trace around the template, then cut a hole 
     in the ceiling following the trace lines.  
 3. Remove the desired conduit knock-out from the top of the QMR 
     housing.
