Safety Messages to Installers, Users, and
Maintenance Personnel
It is important to follow all instructions shipped with this loudspeaker.
This loudspeaker is to be installed by trained personnel who is
thoroughly familiar with the country electric codes and will follow these
guidelines as well as local codes.
The selection of the mounting location for the device, its controls and
the routing of the wiring is to be done under the direction of the facilities
engineer and the safety engineer. In addition, listed below are some
other important safety instructions and precautions you should follow:
• Read and understand all instructions before installing or operating
this equipment.
• Disconnect the device from the power supply/audio source before
any installation or maintenance is performed.
• Do not open the loudspeaker enclosure when a hazardous
atmosphere is present.
• Não abra a cobertura na presença de gases perigosos.
• To determine if the device can be used safely in the intended area,
review the certications section on page 7.
• All effective warning loudspeakers produce loud sounds, which
may cause, in certain situations, permanent hearing loss. Take
appropriate precautions such as hearing protection.
• All effective warning loudspeakers produce loud sounds, which may
cause, in certain situations, permanent hearing loss. The device
should be installed far enough away from potential listeners to limit
their exposure while still maintaining its effectiveness.
• After installation, test the loudspeaker to ensure that it is operating
properly. After testing is complete, provide a copy of this instruction
booklet to all operating personnel.
• Establish a procedure to routinely check the loudspeaker installation
for integrity and proper operation.
• The product nameplate, which may contain cautionary or other
information of importance to maintenance personnel, should not be
obscured in any way.
Failure to follow all safety precautions and instructions may result in
property damage, serious injury, or death.

Unpacking the Loudspeaker
After unpacking the loudspeaker, examine it for damage that may
have occurred in transit. If the loudspeaker has been damaged, do not
attempt to install or operate it. File a claim immediately with the carrier
stating the extent of the damage. If you are missing any parts, contact
Customer Support at [phone]. Carefully check all envelopes,
shipping labels, and tags before removing or destroying them.
Overview of the PAGASYS Series
The Federal Signal PAGASYS Non-Metallic Loudspeakers, Models
P-LS2B, P-LS2B-8, P-LS2C, and P-LS2C-8 are designed for use
in industrial public address and general alarm applications where
corrosion resistance and ATEX/IEC certication are required.
PAGASYS loudspeakers are available in an ATEX/IEC Zone 1
explosion-proof version certied for ingress of dust and combustible
gas to either Group IIB or Group IIC.
PAGASYS loudspeakers are manufactured from corrosion-resistant,
anti-static, glass-reinforced polyester (GRP). The total power output
capability of the P-LS2B and P-LS2C is 25 W, adjustable down to
0.2 W. The available audio input is 100 Vrms. The P-LS2B-8 and
P-LS2C-8 are 8 ohm, 25 W.
The mounting bracket included with the loudspeaker is stainless steel
with two standard mounting holes and a hole for the cable. The bracket
is ratcheted to lock the loudspeaker at a specic vertical angle. Also
available is a stainless steel ratcheted bracket with four additional
mounting holes that are slotted to allow the loudspeaker to be aimed
horizontally.

Setting Transformer Wattage Taps
The Model P-LS2B and P-LS2C loudspeakers have ten wattage tap
settings that enable you to select the loudness of each loudspeaker in
the system (see Table 1 below and Figure 3 on page 14). The higher
the wattage tap, the louder the speaker output. Tighten the terminal
screws to a torque of 0.5 N·m to 0.7 N·m (4.4 in-lb to 6.2 in-lb).
