Notification Appliances—CH Series Chimes and Strobe Chimes 3
Introduction
The CH series electronic chimes and strobe chimes are
UL Listed under Standard 1971 for signaling devices for the hearing impaired and UL
Standard 464 for private mode signal appliances. The CH series chimes and strobe
chimes are manufactured by Wheelock for use with Johnson Controls systems. All inputs
are compatible with standard reverse polarity supervision of circuit wiring by a Fire
Alarm Control Panel (FACP).
CH series strobe chimes incorporate a xenon flashtube with solid-state circuitry enclosed
in a rugged LEXAN® lens to provide maximum reliability for effective visible signaling.
The strobe chimes are available with a choice of four UL 1971 Listed strobe options:
series LS, LSM, MS, and IS. 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.)
All models offer a choice of single-stroke or vibrating operation, have an adjustable
sound level to 83 dBA (anechoic) at ten feet, and have a chime tone adjustable from 800
to 1200 Hz.
