Notification Appliances—E Series Speakers and Strobe Speakers 3
Introduction
The E series speakers and strobe speakers are UL Listed under Standard 1971 for
signaling devices for the hearing impaired and UL Standard 1480 for speaker appliances.
These speakers and strobe speakers are manufactured by Wheelock for use with Johnson
Controls systems. All models offer a choice of field selectable taps for
1/4, 1/2, 1, or 2 watt speaker operation. All inputs are compatible with standard reverse
polarity supervision of circuit wiring by a Fire Alarm Control Panel (FACP).
The E series design incorporates a high efficiency speaker for maximum output at
minimum power across a frequency range of 400 to 4000 Hz, and features a sealed back
construction for extra protection and improved audibility. The optional strobe for the E
series speakers incorporates a xenon flashtube with solid-state circuitry enclosed in a
rugged LEXAN® lens to provide maximum reliability for effective visible signaling. The
strobe speakers are available with a choice of four UL Listed strobe options: series LS,
LSM, MS, and IS. (Refer to the LS, LSM, MS, and IS Series Strobe Signals Technical
Bulletin for specific information regarding these strobe signals.) All models are UL
Listed for indoor use. The LS, MS, and IS models are listed for ceiling or wall mount.
The LSM models are listed for wall mount only, using the backboxes specified in this
document. (See the Mounting section of this document.)
