The Wheelock E50 Fixed‑candela Speaker Strobes meet the
critical needs of the life safety industry for voice and tone
signaling. They have high‑efficiency sound output with dual
voltage (25 VRMS or 70 VRMS) capability and
field‑selectable taps from 0.125 W to 2 W.
The speaker strobes have a sleek, aesthetic appearance for
emergency voice or alarm communication systems. They
easily mount on standard electrical boxes (with no
extension ring required) and incorporate a speaker
mounting plate for faster installation. The cover snaps on so
no mounting screws are visible. Attractive surface boxes are
also available.
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 type
supervision of circuit wiring by a fire alarm control panel
(FACP).
