GENERAL
The PowerTone Model ASHX is a hazardous location, continuous duty,
polarized, 24 Volt dc, indoor/outdoor rated, high output (with internal
volume adjustment), amplified speaker for use with fire alarm systems. It
is suitable for use in areas with high ambient noise levels that require a
loud distinctive signal. A Model UTC tone card (purchased separately)
with different tone settings may be used (see table 2). In addition, one of
two available Model PTCK plug-in connector cards can be used. The
Model PTCK plug-in connector cards will allow use of externally
generated tone or voice signals (see table 2) from a remote audio
amplifier. This model is suitable for use in NEC hazardous locations
Class I, Groups B, C, & D. Its mounting bracket is adjustable to allow
positioning to obtain desired sound coverage.

2. Select mounting location.
WARNING
Property damage, serious injury, or death could occur if any
objects are in front of speaker, severely reducing optimum
sound distribution. For maximum effectiveness, ensure that the
front of the speaker is clear of obstructions.
3. Using the mounting bracket as a template, scribe drill position marks
on the mounting surface. See figure 1 for mounting hole locations and
dimensions
CAUTION
Before drilling holes in any surface, be sure both sides of
surface are clear of anything that could be damaged.
4. Drill holes at the previously scribed drill position marks to
accommodate 1/2" diameter bolts.
5. Secure bracket to mounting surface with 1/2" diameter hex head bolts,
lockwashers and hex nuts.
6. Remove eight 5/16-18 x 1-3/4" hex head bolts, lockwashers and hex
nuts that secure cover to housing and carefully lift off cover.
WARNING
Property damage, serious injury, or death could occur if the
machined sealing surfaces are damaged on this product. To
maintain effectiveness of explosion-proof enclosure, be careful
to avoid damaging the machined sealing surfaces of cover and
housing.
7. Reattach unit to its mounting bracket with two 1/2-13 hex head bolts,
flat washers and lockwashers previously removed. Position speaker
so as to obtain desired sound coverage then tighten these bolts
securely.
8. Before reinstalling the housing cover, read Electrical Connections
below and make necessary connections.
Electrical Connection
DANGER
To avoid electrical shock, do not connect wires when circuits
are energized.
National Electrical Code as well as local codes must be adhered to in the
installation of these models. All electrical wiring must be routed through
approved conduit and fittings as specified.
WARNING
Property damage, serious injury, or death could occur if
suitable barriers are not provided for explosive gases and
other atmospheres. To reduce the possibility of explosion when
this unit is used in Class I, Group B atmospheres, the conduit
MUST have a sealing fitting within 18-inches of enclosure. Be
sure to refer to the National Electrical Code or the authorities
having jurisdiction in the area.
WARNING

sure to refer to the National Electrical Code or the authorities
having jurisdiction in the area.
3. Carefully reinstall housing cover using eight 5/16-18 x 1-3/4" hex head
bolts, lockwashers and hex nuts that were previously removed. Verify
that all housing and mounting bolts have been securely tightened.
PTCK Connector kit installation
WARNING
Property damage, serious injury, or death could occur if
independent conductors are terminated together; both wires of
the same polarity must be used as two separate connections.
NFPA 72 requires that the wires be terminated independently
to provide electrical supervision of the connection, for both the
24 Vdc speaker power and 25 VRMS or 70 VRMS audio lines.
1. Plug the desired PTCK connector card (purchased separately) into the
socket as shown in figure 2.
2. See figure 4. Connect the device’s red (+) leads to the power source
positive (+) lead. Connect the device’s black (-) leads to the power
source negative (-) lead.
3. Connect the white leads from the connector card to the audio input
and outputs.
NOTE
Check with authority having jurisdiction for proper application
of EOL resistor and power supervision relay required (see
figure 4).
WARNING
Property damage, serious injury, or death could occur if the
housing is not closed properly. To reduce possibility of
explosion, housing cover must be kept tight (all eight bolts fully
tightened) while circuits are energized.
4. Carefully reinstall housing cover using eight 5/16-18 x 1-3/4" hex head
bolts, lockwashers and hex nuts that were previously removed. Verify
that all housing and mounting bolts have been securely tightened.

After installation is complete, be sure to test the system to verify that
each amplified speaker operates satisfactorily. If it is found that the unit is
too loud for its location, an internal volume control can be adjusted.
Remove the housing cover and insert a slotted screwdriver with an 1/8"
blade into the hole shown in figure 2. Gently turn control to desired
loudness. Reinstall the housing cover.
After completion of initial system test, establish a program for periodic
testing of this device. Refer to NFPA 72, local Fire Codes and the
authority having jurisdiction for this information.
Provide a copy of these instructions for the Safety Engineer, system
operator(s) and maintenance personnel.
SAFETY MESSAGE TO OPERATORS
Even if your warning system is operating properly, it may not
be completely effective. People may not hear or heed your
warning signal. You must recognize this fact and ensure that
Figure 3: Typical tone card installation wiring
your warning signal achieves its intended effect through
proper test/training sequences within your specific
application(s).
OPERATION/TESTING
