SYSTEMSENSOR PF24V

ExitPoint™
Directional Sounder with
Voice Messaging
Triggered by existing fire detection systems, directional
sounders positioned at carefully chosen locations
guide building occupants along escape routes and to
perimeter building exits.
Features
• Listed to UL 464 (indoor applications only)
• Five field-selectable power settings
• Four field-selectable routing evacuation patterns
• Constructed to be effective in unfamiliar surroundings or poor
visibility
• Designed to work in open areas, corridors or stairs
• Fifteen different language selections available
• Reduces evacuation times by as much as 75 percent
• Optional disable feature for use in conjunction with a control
module or heat sensor
• Low profile, compact design
The ExitPoint directional sounder model PF24V has an integral
audio amplifier that produces a pulsating sound consisting of
broadband low, mid and high range sounds. The broadband noise
makes it possible to determine the location of the sound. There are
four pulse patterns that can be used to create an egress pathway
out of a building and to mark perimeter exits. In addition to the
broadband noise, the sounder is capable of playing an alert message
in the form of a recorded voice message or other audible signals.
These messages will instruct the occupants of what action to take
as they approach the directional sounder, and will allow them to
react quickly and confidently when the sounder is activated. Fifteen
different language combinations are available to instruct occupants
that they are nearing an exit, a stairway up, a stairway down, or an
area of refuge. The PF24V directional sounder also incorporates an
optional disable feature for use in conjunction with a control module
or heat sensor.
The directional sounder features a number of field selectable power
settings including high, medium-high, medium, medium-low, and
low. Installation ease and pleasing aesthetics are achieved by a low
profile compact design, and by the ability to flush mount in a 4˝ × 4˝
× 2¼˝ back-box.
ExitPoint directional sounders, fitted in addition to normal building
evacuation sounders, draw people to evacuation routes in both
good and poor visibility. The PF24V directional sounder can be used
in a wide range of building applications. Trials consistently have
shown an improvement of up to 75 percent in evacuation times in
smoke and up to 35 percent without smoke. The 2007 Edition of
NFPA 72 now provides installation and maintenance guidelines on
directional sounders.
