SAFETY MESSAGE
People's lives depend on your safe installation, test, operation, and
maintenance of our products. Read, understand, and follow all safety
messages and instructions. Refer to "Safety Messages for Equipment
Used in Fire-Protective Signaling Systems" and any other documentation
shipped with equipment before performing any system related duty.
GENERAL
This PowerTone Model ASHH is a continuous duty, polarized,
indoor/outdoor rated, high output, 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.
The PowerTone Model ASHH is suitable for use in NEC Class I, Groups
A, B, C & D, Division 2; Class II, Groups F & G, Division 2; and Class III
hazardous locations. The speaker projector is adjustable and may be
repositioned to obtain desired sound distribution.
INSTALLATION
Unpacking
After unpacking the amplified speaker, examine it carefully for possible
damage that may have occurred in transit. If equipment has been
damaged, immediately file a claim with carrier stating extent of damage.
Carefully check all shipping labels and tags for special instructions before
removing or destroying them.
Mounting Arrangements
CAUTION
To maintain the hazardous location rating of the Model ASHH,
do not use the 7/8” knockout (concealed conduit mounting).
The amplified speaker can be mounted on any relatively flat surface.
Conduit connections can be made to two 1/2" threaded openings at the
bottom of the housing or to 7/8" knockout in rear of housing. A 1/2"
conduit plug is supplied for field installation if one of the 1/2" threaded
openings is not utilized. After the mounting location and mounting method
have been selected, proceed with the applicable instructions below (see
figure 1).
WARNING
Property damage, serious injury, or death could occur if an
accumulation of water, snow, dust, etc. resides in the speaker
projector, severely reducing or preventing operation of this
device. Mount the unit so speaker projector is pointed
horizontally or slightly downward.
Flat Surface Mounting
1. Remove and retain the two screws that secure cover to housing.
Remove the cover.
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.
1. Select the mounting location and place rear of housing against
mounting surface.
2. Using the mounting holes (four (4) in external mounting bracket) as a
template, scribe drill position marks on the mounting surface. See
figure 1 for mounting hole locations and dimensions.
WARNING
Before drilling holes in any surface, ensure that both sides of
surface are clear of items that could be damaged.
3. Secure the unit to a wooden mounting surface with #10 x 1" wood
screws. If mounting on a metal surface, drill 13/64" diameter holes and
secure the unit with #10 screws, lockwashers and nuts.
4. Route power and supervision leads through conduit to the audible
signal. Install a 1/2" electrical connector at the bottom of the audible
signal. Route wires through conduit and electrical connector into the
audible signal housing. Install supplied 1/2" conduit plug if only one
1/2" conduit entrance is used.
WARNING
Property damage, serious injury or death could occur if the
projector is mishandled during installation or over time. DO
NOT rotate the projector more than 180 degrees or internal
speaker wiring may be damaged.
