Internal Connections
The TCM-1, TCM-1A and tCM-1EX plenum is a folded metal enclosure
designed for permanent installation on a ceiling or other horizontal surface,
above a ceiling tile, or on a vertical surface. The devices are passively cooled
and do not have ventilation ports.
A 2-pin connector is located on the inside of the plenum to connect the
pendant microphone. The connector is keyed to prevent incorrect polarity.
The microphone is designed to be suspended by the cable. The length of the
suspended cable is adjustable by pinching the soft plastic on the under-side of
the microphone mount. This allows the cable to be extended or shortened to
the desired length.
Figure 8 Pinch-Points for Microphone Cable Length Adjustment
Strain relief for the microphone cable should be tted using the included zip-
ties by securing it to either the circuit board (TCM-1EX) or the circuit board
protective barrier (TCM-1 & TCM-1A) inside the plenum. Excess cable may be
coiled as shown in the gures below.
Punch-out through-holes in the plenum allow the microphone cable to exit either
vertically or horizontally through the microphone mount. Keyed mounting holes
allow installation on a vertical or horizontal surface or above a ceiling tile. The
plenum design allows for an optional seismic cable to be connected.
If installing the microphone away from the plenum, the cable will be routed
through a punch-out through-hole and a strain-relief grommet (included) must
be installed to prevent damage to the microphone cable.
NOTE: Make sure there’s sucient cable slack outside the plenum to
accommodate potential changes in microphone height.
CAUTION: Make sure the cable is not strained or the zip-tie overtightened as
damage may occur.
