4 Gather all ceiling tiles (per layout drawing) that are to receive emitters. Use the supplied hole saw to cut
holes in designated tiles. Cut all tiles from the front. (Different types of emitter housings are available to
attach in areas where there are no suspended ceiling tiles.)
5 Push the emitter through the front of the hole in tile and secure it by pushing down and twisting the locking
ring at the back of the emitter.
6 Connect a run cable from the specified zone OUTPUT jack on the module to the INPUT jack of the first
emitter. Listen to each emitter as it is connected. If you cannot hear its “whooshing” sound:
• Try a different emitter.
• Test all four previous cables for continuity and shorts. Repair any faulty cables.
• If there is a short, circuit protection will engage, and masking volume will shut off. Once the short is fixed, the protection
state should clear itself in approximately five minutes.
7 Connect the next OUTPUT cable to the emitter OUTPUT jack.
8 Run the cable to next designated tile specified on emitter layout and wiring diagram. Tie cables up to
structure or suspend from deck as required by local building code.
9 On the next emitter, connect this cable to the INPUT jack.
10 Repeat Steps 4 through 9 for the remaining emitters on the home run.
11 Set sound masking volume levels for each zone, using either the front panel controls or the software
interface. Set sound levels according to Table 1.
12 If a small area within a zone exhibits a perceived volume louder than the rest of the zone, due to a
difference in acoustics, use the adjustable rocker switch on the back of each related emitter to turn the
volume down (by 3, 6, or 9 dB from the value set at the controller). See emitter spec sheet for more details.
Be sure to fix any problems and hear the “whooshing” sound before installing the next emitter. If necessary see
the Error Codes section of this guide, found on page 32.
Active Emitter Installation
Before masking output volume can be set for zones with Active emitters, the emitter Type and Masking
Spectrum for those zones must to be configured within the MCS software. Refer to the MCS Operations
section later in this document
NOTE:
• The input jack of each emitter bears this symbol and is located near the safety tie off.
• The output jack of each emitter bears this symbol.
NOTE:
• The “tombstone” hook on the back of each emitter is next to the INPUT jack.
• This can help you find the INPUT jack by touch.
• To adjust for unexpected obstacles such as sprinkler heads, each emitter maybe moved up
to 2 ft. (one tile or 0.6 m) in any direction.
