Survival of
the fittest
Typical EST3 Wiring
with Security, Access Control,
Emergency Voice/Alarm
and Firefighter's Telephones
Multiplex fire, security, and access control
Whether for fire alarm only, or for total life
safety protection including security and
access control, the EST3 network is the most
survivable system available.
EST3 uses distributed database technol-
ogy, designed to survive the rigors of fire and
firefighting. In Class B configuration a single
break on the network wiring will isolate the
system into two groups of one or more nodes.
Each group of nodes continues functioning
as a peer-to-peer network, working with
their combined databases.
In Class A configurations a single break or
short on the network wiring causes the
system to isolate the fault. Network commu-
nication continues uninterrupted. If multiple
faults occur, the network re-configures into
multiple networks. This means a system
continues to respond to activations from
every node that can transmit and receive
network messages. Local responses always
execute because the local database resides
at each node.
Exceptional survivability extends to every
EST3 function, including security and access
control. These devices (highlighted in yellow)
reside on the network alongside fire alarm
components. They share wiring, power sources
and the inherent stability of a fire alarm
network engineered to meet standards far
beyond those of ordinary security systems.
Yellow denotes security and access control components
