Fire and Gas Alarm Notification Appliances for Large, Noisy

Fire and Gas Alarm Notification Appliances for Large, Noisy
Fire and Gas Alarm Notification Appliances
for Large, Noisy Industrial Facilities
Louder Horns and Brighter Strobes offer Better Warning and Greater Effective Coverage
Noisy machinery, hearing protection in use, distractive procedures,
process alarms, bright lights, molten sparks, moving equipment,
poor visibility, confined spaces, obstructed areas - these are just
some of the factors affecting the ability of workers to be notified of
a dangerous situation inside an industrial facility.
Mass notification system design must take ambient noise as well as
sounder performance into consideration when ascertaining the effective coverage area of an alarm horn. Likewise, installation location and proximity to workers is vitally important for strobe lights.
With modern designs, Pfannenberg signaling devices possess the
performance characteristics needed to fulfill NFPA requirements
for evacuation alarms in and around industrial facilities.
Pfannenberg’s Modern Signaling Devices Provide Advanced Features and Benefits
Brighter Strobe Lights Deliver Superior Visual Notification:
Choice of 5, 10, or 15 Joules flash energy to ensure adequate warning over specified coverage areas.
Pyramid shape with prismatic lens achieves the most effective light dispersion in all directions.
Rated lifespan of 8,000,000 flashes.
Strobe can be controlled simultaneously or independent from audible alarm sounder.
Adjustable flash rate and automatic flash sync for multiple units (some models).
Choice of lens colors to suit specific applications: clear, white, yellow, amber, red, green, blue.
Louder Horns Deliver Superior Audible Notification:
• Sounder includes onboard choice of 80 unique tones - many conforming to international alarm standards.
• Multiple alarm stages permits one device to emit a different tone for up to 4 distinctive events.
• Choice of 100, 105, 110, and 120 dB(A) (SPL) nominal output levels to ensure adequate warning
over specified coverage areas.
• Optimized horn design projects audible signal for greatest effective range.
Other Features Common to All Models:
• 10-year warranty.
• Quick, safe, and error free installation.
• Optional tamper-proof fastener plugs.

Effective Coverage Area Must Be Considered
for Notification Appliances in Noisy Facilities
Horn Design and Strobe Intensity Play Vital Roles for Successful Hazard Alarming
Comparing coverage area for two competitive 100 dB sounders:
The polar diagrams at left depict third party test results for two multi-tone
sounders, each claiming on their respective data sheets to generate 100
dB(A) at 1 meter.
These plots show the actual effective range over a 180° projection. For this
test, the same DIN tone (German emergency signal) was selected from the
tone menu of each unit. Also, the effective SPL is assumed to be 75 dB(A),
derived from: 65 dB(A) ambient SPL plus 10 dB(A) desired alarm offset - so
the outer boundary of the shaded areas are the distances at which the SPL
has dissipated to 75 dB(A). The red lines depict a “smoothed” performance
from which the square meter coverage area is computed. Note: The distance axis has been scaled to fit the diagrams into a similar space.
Digisound Model BSE 128
Effective area for minimum 75
dB(A) SPL is 48 square meters.
Pfannenberg Model PA 1
Effective area for minimum 75
dB(A) SPL is 678 square meters.
Conclusions: 1). The actual effective coverage area can vary significantly
between units that are marketed to have the same output SPL on their
data sheets. 2). The sound projection geometry is a function of the efficiency of the horn design. 3). Installation location, such as the maximum
height at which the unit can effectively be located, is a function of the coverage area and projection geometry. 4). Data sheet information alone is
typically insufficient for sizing and suitable installation location purposes.
Strobe light considerations:
For large facilities with high ceilings, it is necessary to consider the effective light output range for strobe lights. Whether ceiling or wallmounted, the coverage area must be adequate to satisfy NFPA and EN standards.
