Intended for private mode applications, the SpectrAlert chime meets UL 464 and the
chime/strobe meets UL1971.
Flexibility.
SpectrAlert products offer the flexibility to meet a broad range of
requirements. SpectrAlert chimes and chime/strobes feature sixteen field-select-
able electronic tones, with three different volume levels for each. Chime/strobe
models are available in 15, 15/75, 30, 75, and 110 candela configurations.
Installation.
SpectrAlert chime and chime/strobe offer DIP switch tone selections
to simplify field configuration. In addition, each device mounts to standard
depth back boxes for greater installation flexibility. Small footprint or surface-
mount accessory mounting plates are available for the chime.
