Flying using Eyebolts
WARNING: As the legal requirements for fl ying change fom country to country, please consult
your local safety standards offi ce befoe installing any product. We also recommend that you
thoroughly check any laws and bylaws prior to commencing work.
The device can also be hung via 4 top-mounted eye bolts. Rear of back can has mounting points for
both M10 and 3/8 UNC threaded eyebolts.
Flying Using Screwed Rod
The design also caters for a single point central hang via M10 or 3/8 UNC screwed rod – made easy
thanks to the slotted mounting saddle on the top of the back-can. If required a safety wire can be
attached to any of the M10 fl ying points.
To fi t the back can to theaded rod support, fi rst run a nut 50 mm (2") up the od followed by two
plain washers and then a locking nut (Nyloc). Hook the back can on to the rod between the two
plain washers. Once the nut has cleared the guide slot the top nut can be locked down to secure.
Fitting the loudspeaker assembly
Mounting of the loudspeaker assembly to the pre-installed back-can is a one man job thanks to the
common sense design approach. One edge of the baffl e clips onto the steel box to hold it in place
while the installersecures the assembly in place. Connection is simple via terminal barrier strips inside
the can, easily accessible via 20 mm (0.79") and 29 mm (1.14") conduit knockouts on all fi ve sides of
the can. Saving time and manpowerduring installation has been a driving factor behind the design of
the CMS 1201 system.
Baffl e assemble can be hooked onto the back can with care.
