Features
• Wall-mount models available with field-
selectable candela settings of 15/30/75/
110 cd on multi-candela models, or 15/75
cd on non-selectable model.
Series E
Speaker/Strobes
• Ceiling-mount multi-candela models are
available with field-selectable candela
settings of 15/30/75/95 cd or 115/177
cd, depending on model.
• Strobes produce one flash per second
over the regulated voltage range.
Description
• Zero inrush above peak.
Series E low-profile speaker/strobes
are designed for high-efficiency
sound output, with dual voltage
capability (25/70 VRMS) and field-
selectable taps from 1/8 to 2 watts.
The low-profile design incorporates
a speaker mounting plate for faster
and easier installation. Each model
has a built-in level adjustment
feature and an attractive grille
cover with two flush screws.
• Strobes operate at 24 VDC with wide UL
“regulated voltage” using filtered DC or
unfiltered VRMS input voltage.
• Synchronize strobes with SM or DSM
sync modules (P/N 51548, 51549) or FF8
power supply with built-in sync protocol.

• Field-selectable taps for 25 or 70 VRMS
operation from 1/8 watt to 2 watts.
• High-efficiency design for maximum
output at minimum wattage across a
frequency range of 400 to 4000 Hz.
The Series E speaker/strobe models
incorporate the low-current, zero-
inrush, Series RSS non-sync/sync strobe. Strobe options include 15/75 cd or
multi-candela strobe with field-selectable candela settings of: 15, 30, 75, or 110
cd (wall); or 15, 30, 75, or 95 cd, or 115/177 cd (ceiling, depending on model).
• Fast installation with in/out screw
terminals using 12 to 18 AWG (3.1 to
0.78 mm²) wires.
Speaker/strobe sound output
• 1/8 watt: 77.5 dBA @ 10 ft (3.048 m).
• 1/4 watt: 80.4 dBA @ 10 ft (3.048 m).
• 1/2 watt: 83.2 dBA @ 10 ft (3.048 m).
• 1.0 watt: 85.7 dBA @ 10 ft (3.048 m).
• 2.0 watt: 87.8 dBA @ 10 ft (3.048 m).
Series E speaker/strobes provide high audio output with clear audibility,
and are designed to meet the critical needs of the life safety industry for
effective emergency voice communications, tone signaling, and visible
signaling to alert the hearing impaired. The strobe portion of all Series E
speaker/strobes may be synchronized when used in conjunction with the SM
or DSM (P/N 51548, 51549) sync modules or the Gamewell FF8 power
supply. Synchronized strobes offer an easy way to comply with ADA recom-
mendations concerning photosensitive epilepsy. Series E speaker/strobes
are listed for indoor use, with a temperature range of 32°F to 120°F (0°C to
49°C) and a maximum humidity of 85%.
