The Wheelock ET80 High‑candela Speaker Strobes meet the
critical needs of the life safety industry for voice and tone
signaling. They have a vandal‑resistant die‑cast grill, a
sealed‑back speaker, and a Lexan lens for extra protection.
The high‑efficiency speaker is designed for maximum
output at a minimum wattage across a frequency range of
400 Hz to 4 kHz. It covers both 25 V and 75 V audio systems
with a series of wattage taps from 0.125 W to 8 W.
When used with the SM (single) or DSM (dual)
synchronization modules, the strobe produces a
synchronized strobe flash for compliance with ADA
guidelines concerning photosensitive epilepsy. All strobe
input is compatible with standard reverse polarity
supervision of circuit wiring by a fire alarm control panel
(FACP).
