the Hearing Impaired and UL Standard for Private Mode Audible Signal Appliances. The CH70-24MCW Chime Strobe is designed for
low current draw and versatile performance. This model offers a choice of single stroke or vibrating operation, has adjustable sound
level to 83dBA (peak anechoic) at 10 feet, and has a chime tone adjustable from 800 to 1200Hz. The CH70-24MCW Multi-Candela
strobe provides four selectable light output intensities in one unit. This appliance also incorporates a Chime Mounting Plate attached
to the chime for ease of installation. The Chime Strobe model can provide a non-synchronized strobe appliance when connected
directly to a Fire Alarm Control Panel (FACP), or provide a synchronized strobe appliance when used in conjunction with a Sync
Module (SM), Dual Sync Module (DSM) or the PS-12/24-8 Power Booster. The strobe uses a Xenon flashtube with solid state circuitry
enclosed in a rugged Lexan
lens to provide maximum visibility and reliability for effective visible signaling. The CH70-24MCW is
Listed for
indoor use, wall mount only
with the backboxes specified in these instructions (see Mounting Options).
