PowerTone Model SPL Low Profile Series speakers are
designed to reproduce electronically generated warning
tones and full range voice communication. The speakers
are designed for 25 and 70 volt UL Listed audio systems.
Unlike conventional fire alarm speakers, Model SPL Low
Profile speakers can be mounted in a standard depth, 4"
square back box with no extension ring. Wattage can be
adjusted to 1/4, 1/2, 1, and 2 watts by simply moving a clip to
the desired tap setting. The SPL speaker is designed for
connection to system supervised alarm notification circuits.
An optional auxiliary terminal is available. CPG Model
V1971 synchronized strobe lights are available as an option
when visual signaling is required. Strobes can be synchronized
using Model VSYNC sync module.
The PowerTone Low Profile Series speakers produce a
broad frequency range which provides both the low and hifidelity
response required for effective tone and voice alarm
notification. Available mounting options include 7-3/16"
diameter round or 5-3/4" square vinyl clad metal plate grills
and also a patented, folded 4-1/2" square re-entrant housing
which are available in red or white. Re-entrant models may
be flush mounted using CPG FBL backbox or surface
mounted on a standard four inch backbox. Plated models
require a standard four inch backbox for mounting. For
complete mounting information see instructions (#2561121).
