Customer Microphone
Assembly Installation
STS-C100 Anti-Vandal Microphone with Glass Mount Kit
The microphone bracket is balistically tested to threat level IIIA, test
standard:modied/abbreviatedNIJ0108.01.
1. Conrmtheholeintheglassisbetween2½and4½inchesin
diameter.
2. Separate the front and rear polycarbonate plates.
3. Place the customer facing plate (containing the stainless steel
microphonecapsule)onaatsurface,withthecapsulefacing
downwards.
6

4. Screw an 8-32 2” stud into every second hole (three total).
5. Feed one blue rubber gasket through the microphone wire and align
the holes with the three studs. Then, push the gasket down so that it
isushonthepolycarbonateplate.
6. While standing on the customer-side, feed the microphone wire
attached to the front polycarbonate plate through the opening of
theglassbarrierandontothestaside.
The microphone capsule should point forward, towards the
customer standing position.
7

7. When the end of the wire is reached, hold the front polycarbonate
plateushtotheopeningintheglassbarrier.
Use tape to temporarily secure the front polycarbonate plate to the
window, ensuring it holds the plate and the microphone capsule
securely.
8. Movetothestaside.Feedthesecondbluerubbergasketthrough
the microphone wire, aligning the holes of gasket to slip it onto the
three8-322”studsandushagainstthescreen.
9. The assembly kit is supplied with 3 feet of stainless steel tubing,
designed to conceal and protect the microphone wire routing on the
screen.
• The tubing may be separate from the microphone wire or have
the wire inside it already depending on the model and sup-
ply setup. If your tubing is separate, insert the wire into it and
thread through.
8

• The tubing with the microphone wire should be positioned on
theinsideofthescreen(staside).Itcanbecuttothesize
required.
• Thetubingandwirecanbettedinanydirectionbyturningthe
plate around to the desired direction: vertically, diagonally, or
horizontally. Note: Assistance from another person on the other
side of the screen may be required.
10. Measure and cut the metal tubing to the required length. Feed the
wire through the tubing until reaching the end. The tubing may be
benttoadesiredconguration.
Note:
• Tubing is held into position by the two polycarbonate plates.
The edge of the tubing is pressed between the plates and
shouldbelocatedinthedesignatedingressofthestaside
plate. The tubing is designed to run along the window surface,
concealing the wire and leading it neatly to the screen edge.
• Depending on the type of your screen and length of the tubing
used, a self adhesive cable clip might be required to hold and
support the far end of the stem into position on the screen.
• If you require tubing in longer lengths please contact the
manufacturer as longer lengths are available to order.
11. Alignandplacetherear(sta-facing)plateontothestuds,ensuring
the metal tubing is pointing towards the direction you require.
9

12. Screw in three of the 8-32 2” screws into the three empty holes in
the plate, tightening enough to hold all the pieces together. Note:
You may need to lift the unit slightly to properly align the screws.
13. Nowremovethealignmentstudsbyunscrewingthemandreplace
them with the remaining three 8-32 2” screws.
14. Tightenallsixscrewsina“star”conguration.Tighteneachinsmall
increments until all screws are completely tightened and the two
platesareheldrmlyintoposition,securelyholdingthestainless
steel tube with the wire.
15. Route the microphone cable from the edge of the screen back to the
amplierinaneatandtidyfashion,usingcablecontainmentwhere
required.
16. Plug the green connector into the ‘Cust Mic’ port on the back of the
amplier.
17. Remove the tape holding the customer side plate and the
10

microphone capsule.
18. The microphone and speaker installation is now complete. The
system should resemble the unit on the following page (dependant
on the tubing set up).

Customer Speaker Installation
STS-S23
The intended location of the speaker is on a window frame, secured
tightly with supplied screws.
The speaker can be installed onto metal, wooden or plastic frames,
at either the top of a screen or on the sides. The speaker angle can be
adjustedtopointtowardsthecustomerforbettersound.
The optimum installed height is 6-8 feet from the customer.
Environments with background noise may require a lower installation.
1. Find a location on the customer side directly above the glass barrier
where interactions will take place. Ensure there is enough space to
drill and there is no glass behind the material.
2. Checkthecableroutebacktotheamplierlocationunderthe
counter, considering cable length and access through countertop.
3. Markthexingpointstomountthespeakerbracketwhileensuring
there is access to retrieve the cable.
4. Drillxingpointsusingadrillbitsmallerindiameterthanthe
screws that will be permanently installed.
5. Alignthespeakerbracketwiththexingpoints.
6. Mountthebackplateusingtheappropriatescrews/xings.
7. With the cable facing down, slip the screws on the side of the
speakerintothegrovesofthebracket.Adjustthepositionofspeak-
er and tighten screws to secure in place.
8. Routethecablefromthespeakerbacktotheamplierinaneatand
tidy fashion, using cable containment where required.
9. Plug the speakers’ connector into the “Cust Spkr” port on the back
oftheamplier.

counter.
2.
Plug the unit’s connectors with BLACK and YELLOW wires into the
“StaSpkr”portonthebackoftheamplier.

Hearing Loop Installation
IL-AE98 Window Mount Hearing Loop
TheIL-AE98WindowMountHearingLoopshouldbeinstalledonthe
screenonthestaside.
Ensure hearing loop signage is displayed clearly.
Determine the location of the hearing loop aerial on the glass
barrier. Make sure to place it directly in front of where a customer
will stand. It is recommended that the unit is placed on the bottom
corners of the glass barrier for optimal performance. Do not
exceed 2 feet above the average standing customer.
1.
Clean the area with a glass cleaner and thoroughly wipe dry.
2.
Remove the liner on the blue sheet with a faint outline of the
international hearing loop signage to expose the adhesive backing.
Please note that both sheets are not solid blue.
3.
Carefully attach the sheet on the glass barrier with the international
hearing loop signage facing the customer. Slowly apply to glass
barrier while smoothing out air bubbles with straight-edged tool.
4.
Remove the liner on the solid blue sheet, exposing the adhesive.
5.

Carefully apply the hearing loop aerial with the attached cable
to the adhesive on the solid blue sheet. Ensure the cable is at the
edge of the sheet, and the wire is coming from the back side of the
aerial when applied.
6.
Attach the solid blue sheet with hearing loop aerial to the sheet
attached to the glass barrier. Slowly apply while smoothing out air
bubbles with straight-edged tool.
7.
