System overview
1.40 EST3 Installation and Service Manual
Note:
The EST3 amplifiers operate in a stand-alone mode should
they lose communication with the Audio Source Unit. The alarm
tone used in the alarm message should be the same tone used by
the amplifier for stand alone alarm signaling.
Alert message format
The basic alert message consists of an alert tone followed by an
advisory message. The suggested alert tone should be easily
differentiated from the alarm tone and can take the form of a
constant tone, or a constant tone modulated at a 20 pulse per
minute rate. Please refer to the Authority Having Jurisdiction for
specific requirements.
Typical Alert message text:
Female Voice: “May I have your attention please. May I
have your attention Please.” Male Voice: “There has been an
emergency reported in the building.” “Your area is in no
immediate danger.” “People from other areas of the building
may be entering your area.” “Be prepared to leave the
building if you hear the evacuation signal.” “Repeat, you are
in no immediate danger.”
Informative messages
Informative messages are those special purpose signals to areas
of the facility which may have special concerns during an
emergency situation. Typically these areas include elevator cabs,
stairwells, and areas in less peril than those areas receiving the
Alert signal. Some sample informative messages appear below.
Elevator message text:
Female Voice: “May I have your attention please. May I
have your attention Please.” Male Voice: “There has been an
emergency reported in the building.” “The building manager
has directed the elevators to the lobby.” “Please exit the
building when you reach the lobby.”
Stairwell message text:

assigned re-entry floor or the lobby.” “Do not attempt to use
the elevators.”
Do Not Enter message text:
