4. Two or Three WTSDs with a WTSD-PWHUB and one WTSD receives audio and wakes
up.
A. All WTSD panel sleep indicators illuminate yellow.
B. One of the WTSDs receives audio and wakes up from sleep mode and the sleep
indicator turns Off. The other WSTD Sleep indicator(s) remains yellow.
C. The woke WTSD audio output is unmuted passing audio onto the BUS. The other
WTSD(s) remains locally muted.
D. The WTSD-PWHUB sleep LED is not illuminated.
E. The WTSD-PWHUB auto sleep port relay goes from Normally Open (NO) to
Normally Close (NC) contact position. This voltage can be used to unmute an audio
system or to turn On any equipment such as amplifiers or power strips.
Things to Consider Before Installation
1. Select the correct mounting method. It is critical to fit the WTSD and the wires in
the box without causing damage to the WTSD. Refer to the section “Choosing a WTSD
Wall Mounting Method” for details on selecting the correct mounting method for the
application.
2. Check for local electrical codes for low voltage installation requirements.
3. Do not use shielded Cat5/6 cable. The RJ45 connectors on the WTSD do not have a
ground connection for the shield, so it is not necessary. The STP Cat6 can also be less
flexible when installing in a back-box.
4. If using a WTSD outdoors, make sure the optional WTSD-COVER is used and do not
expose directly to rain or snow. At minimum, place under an eve.
Things to Be Careful of During Installation
1. If using a shallow electrical back-box do not stuff the cables if there is no room. This
can damage the WTSD.
2. When running the Cat5/6 cable use standard IT wiring practices. If not, noise
interference can happen.
3. Avoid AC mains power. Never run the WTSD BUS cable parallel next to AC 120V – 240V
electrical runs and stay clear of AC outlets, or unwanted noise pick up can occur.
4. Using low grade / cost RJ45 connectors can cause an intermittent connection and
popping in the audio system may occur.
