EST3 is a modular system uniquely designed to

easily meet the needs of standalone single node

systems or multimode networks. Fire alarm,

security, access control and audio functions use

the same fundamental components, simplifying

system layouts.

EST3 is a superbly adaptable life safety system,

lending itself to medium and large building

applications. Cabinets are available with room

for system batteries up to 65 Amp hours. With EST3, one 24-volt battery supports up

to four power supplies. Each supply will support up to 7 Amp load. With four supplies,

28 Amps of current is available — all backed up by a common battery.

EST3 operates on a multi priority peer-to-peer token ring network. The multi-priority

token ring gives EST3 exceptional response. EST3 token ring network configuration

also permits vast distances between nodes. The allowable distance between nodes on

#18 AWG (0.75mm2) is 5,000 ft (1,523 m). With 64 nodes supported on a network,

the total network length is in excess of 300,000 ft (91,400 m), or nearly 60 miles! A

single node supports up to 10 Signature loop controllers with 250 devices per loop,

(2,500 points total per node, 160,000 points per network).

Taking full advantage of digital technology, up to eight channels of audio sources can

be sent over a single twisted pair of wires between nodes. Coupling the inherent

reliability and performance of zoned amplifiers with EST3 simplified user interfaces

makes audio system design and operation both easy and dependable.

EST3 is the right choice for any medium to large application. Its multiplex functions

are second to none in the industry today.
