u Choice of two strobe lens colors with range of

intensity options

u Field‑selectable voltages of 25 VRMS or 70 VRMS

and powers from 1/8 W to 2 W

The Wheelock E70 Colored‑lens Speaker Strobes are
effective for alerting personnel in industrial, military,
or government applications. They are ideal for mass
notification systems and for emergency, warning, or
trouble notification in many industrial operations. They
are not listed for fire alarm use but are built with the
same high‑quality circuits and parts used in
Wheelock's life safety speaker strobes.
These speaker strobes are available in amber or blue
lens colors and include multi‑candela models with four
field‑selectable settings and high‑candela (110 cd)
models. The speakers have field‑selectable voltages
(25 VRMS or 70 VRMS) and powers (1/8 W, 1/4 W,
1/2 W, 1 W, or 2 W). They are designed for indoor use
and can be either wall or ceiling mounted on standard
electrical boxes.
