Brooks Occupant Warning System is a single evacuation zone system designed to provide
warning to the occupant to evacuate the building in the event of fire or emergency. The
speaker circuit can split up to 48 supervised speaker circuits using 12 x 4 zone splitter
cards SUB999 that can be fitted in FT1020G3, numbers are dependent on the available
space in the standard cabinet, larger enclosures can be used to allow for more options.
The OWS comprises an amplifier, control / indication front, optional zone splitter cards and
speakers / strobes distributed within the building to provide audible and visual warning to
the occupant as well as PA notifications. In addition to the T3, the OWS provides in its
standard configuration alert and evacuation messages as well as electret microphone for
PA purposes. Dynamic hand-held microphone can also be used on request.
The Brooks OWS provides high quality audio output utilising high efficiency class D
amplifier, sizes available: 60W, 120W and 225W
