Network Audio
Configuring EST3 audio is a matter of selecting components for installation in standard
fire alarm cabinet assemblies. EST3 uses zoned amplifiers. This reduces wire runs and
space needs at a central location. Audio control equipment and zoned amplifiers use
the same system power supplies as fire alarm components. All these components are
supported by a common standby battery. Where multiple nodes make up the system,
a single pair of wires carries eight channels of digital audio between nodes.
Audio and Telephone Masters
The Audio Source Unit converts analog signals to digital signals.
Sampling the analog signal 9600 times per second provides
high quality reproduction of audio sources. On-board audio
memory stores signal tones and/or alarm-alert verbal mes-
sages. The ASU comes standard with two minutes of memory for
tone and message storage. Available message memory expands
easily to 32 minutes with the optional 3-ASUMX/32 memory
expansion card.
Audio Source Units support connection of a local microphone,
remote microphone, telephone voice line, and auxiliary audio
input. With eight audio channels to choose from, combinations
of paging, alert, evacuation signaling and automatic mes-
sages are available for simultaneous delivery to different parts
of a building.
When the system requires paging, only the 3-ASU or 3-ASU/4
Audio Source Units provide a master paging microphone with
common controls. Switch labeling makes the operation intui-
tive. Six LEDs and five switches cover paging operations.
Audio Source Units mount in one chassis space of a EST3 Lobby
Enclosure. In addition to the paging microphone, the 3-ASU/4 has
mounting space for up to four local rail modules, including 20, 40,
and 90 watt zone amplifiers, and up to four Control Display
modules. This increases layout flexibility. The 3-ASU provides the
same functionality as the 3-ASU/4 but is supplied with an inner
door filler plate and no local rail module spaces.
The 3-FTCU contains the master telephone handset that pro-
vides an analog telephone riser for two-way communications
between the fire command station and firefighter’s telephone
stations installed in the facility. The 3-FTCU features an alpha-
numeric display that indicates both incoming and connected
calls. Up to five remote telephones may be connected to the riser
simultaneously. The fire command center operator can also use
the telephone circuit as a page source, permitting paging via
the telephone system.
