Wheelock CH Chime

GENERAL CH Series Electronic Chimes minimize alarm power supply and wiring costs with a low current of just 20 mA These unique solid state chime sig provide field selectable single stroke or vibrating op with sound level adjustable up to 83 peak dBA and adjustable from 800 to 1200 Hz They are available two attractive package styles for flush mounting to stan electrical boxes or convenient surface mounting CH70 and CH90 models incorporate a new patent chime mounting plate for faster easier level with a new two 2 screw grille cover for a aesthetically pleasing appearance Additionally the Series Chime Strobe models incorporate the new current reduced inrush Series RSS Non Sync Sync synchronization of the strobe flash is achieved used with Wheelock SM or DSM sync modules Chime Strobes are designed for maximum perfor reliability and cost effectiveness while meeting or the latest visible signaling requirements of NFPA the National Fire Alarm Code ANSI 117.1 the Ameri National Standard of
