Safety Messages
It is important to follow all instructions shipped with this product. This device is to be
installed by trained personnel who are thoroughly familiar with the country electric
codes and will follow these guidelines as well as local codes.
Planning
• If suitable warning equipment is not selected, the installation site for the DSA1X
Speaker is not selected properly or the DSA1X Speaker is not installed properly, it
may not produce the intended optimum audible warning. Follow Federal Emergency
Management Agency (FEMA) recommendations.
• If DSA1X Speakers are not activated in a timely manner when an emergency
condition exists, they cannot provide the intended audible warning. It is imperative
that knowledgeable people, who are provided with the necessary information, are
available at all times to authorize activation.
• When DSA1X Speakers are used out of doors, people indoors may not be able to
hear the warning signals. Separate warning devices or procedures may be needed to
effectively warn people indoors.
• The sound output of DSA1X Speaker is capable of causing permanent hearing
damage. To prevent excessive exposure, carefully plan placement, post warnings, and
restrict access to areas near sirens.
• Activating the DSA1X Speaker may not result in people taking the desired actions
if those to be warned are not properly trained about the meaning of warning sounds.
Users should follow FEMA recommendations and instruct those to be warned of
correct actions to be taken.
After installation, service, or maintenance, test the system to conrm that it is operating
properly. Test the system regularly to conrm that it will be operational in an emergency.

General Description
DSA1X Speaker
General Description
Introduction
The DSA1X Speaker is a 100-watt non-amplied speaker that can be powered from
Federal Signal UltraVoice controllers or any 25 or 70 V amplier system and can be
used in hazardous locations. Use the DSA1X as a warning and alert device with audible
signals (tone or voice).
The DSA1X is an addition to the DSA family, and can be combined with the DSA2,
DSA4, and DSA6 for exible mass notication designs. The DSA1X includes stainless
steel mounting hardware for wall or ceiling mount. Optional mounting brackets include
large or small mounts and a unique omnidirectional mounting bracket. The DSA1X
enclosure has multiple access points to allow installation of strobes, sensors, or lights.
The DSA1X Speaker is an ideal solution for existing notication systems where lack of
coverage exists, but the coverage area does not require the higher power levels of the
larger DSA Speakers.
The DSA1X is designed for outdoor use and large indoor structures. All wiring interfaces
are accessible through internal connectors and built-in NPT entrances for quick and easy
installation. If the NEC or Local electrical codes allow for using a cable gland, the gland
must be Listed. The DSA1X has ¾ inch and ½ inch NPT entry sizes.
The DSA1X comes with an adjustable stainless-steel wall mount bracket that allows the
angle of the speaker to be adjusted. Optional pole mount brackets are available for small
and large diameter poles.
Features
The DSA1X has the following features:
• Indoor or Outdoor 100-watt tappable speaker with high powered voice and tone
• 25 Vrms and 70 Vrms audio input taps
• Speaker rated at 120 dBa for tones and 114.5 dBa for voice at 10 feet (at 100 W)
• 100 W, 55 W, 32 W, and 18 W output taps (See Table 2 for specications.)
• Wall or pole mount available, wall mount standard
• NEMA 4X outdoor rated
• Multiple access points for mounting of optional equipment
• This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D; Class II,
Division 2, Groups F and G; Class III.

Installation
DSA1X Speaker
Installation
Read and adhere to all safety warnings in this manual before installing the
DSA1X Speaker.
Electrocution or severe personal injury can occur when making electrical
connections, drilling holes, or lifting equipment. Therefore, experienced
electricians in accordance with national and local electrical codes, acting
under the direction of the installation crew safety foreman, should perform
installation.
Determine a Suitable Location
The DSA1X can be mounted on any relatively at surface with the supplied mounting
brackets. The mounting surface must be capable of supporting the weight of the speaker.
This equipment is suitable for use in Class I, Division 2, Groups A, B, C, D; Class II,
Division 2, Groups F and G; Class III or nonhazardous locations only.
Wall Mounting
The DSA1X Speaker comes standard with a bracket for vertical wall or pole mount with
optional pole accessories. The standard mount can be ipped to allow ceiling mount.
To wall mount the DSA1X Speaker, do the following:
1. Find suitable location to mount speaker. Use industry or company preferred practices
when mounting hardware to structures.
2. Verify the mounting is adequate to hold the weight of speaker, cables and visual
devices, if equipped.
3. Refer to Figure 3 or use the U-shaped wall bracket as a template to scribe the
mounting hole locations.
4. Mount the DSA1X Speaker to the mounting surface with user-supplied hardware.
Federal Signal recommends 3/8 in fasteners.
5. Loosen the pivot bolts to provide the direction of the speaker.
Attaching the Mounting Brackets to the Speaker Housing
Do the following to attach the brackets:
1. The mounting brackets are attached to the speaker as shown below using the six
supplied ¼-20 x 5/8 in screws.
Note the orientation of the curved slots on the L-shaped brackets, this orientation is
important to allow the speaker to be pivoted downward.
2. Tighten the ¼-20 x 5/8 in screws to approximately 80 in-lb.
