The strobe has a 75 candela intensity on axis at -31°F 
(-35°C) and 180cd at 77°F (25°C) with low current 
draw. For outdoor applications the ET70WP–2475W-
FR must be wall mounted to a Weatherproof Back Box 
(IOB). The speakers are designed for multiple power 
requirements with high dBA output at each power tap. 
The low profi le model offers a choice of fi eld selectable 
taps, 1/8W to 8W for either 25.0 VRMS or 70.0 VRMS 
audio systems. The low profi le design incorporates 
a high efficiency speaker for maximum output at 
minimum power across a frequency range of 400 Hz 
to 4000 Hz and features a sealed back construction 
for extra protection and improved audibility. The low 
profi le speaker strobes can provide non-synchronized 
operation when directly connected to the Fire Alarm 
Control Panel, or synchronized strobe operation when 
used in conjunction with a Wheelock Sync Module 
(SM), Dual Sync Module (DSM), or Wheelock Power 
Supplies (PS-12/24-8CP and PS-12/24-8MP)  with built-
in patented sync protocol. The strobes use a Xenon 
fl ashtube with solid state circuitry enclosed in a rugged 
Lexan lens to provide maximum visibility and reliability 
for effective visible signaling.
