Edwards EST3 Emergency Communication and Life Safety Platform

Edwards EST3 Emergency Communication and Life Safety Platform

Product positioning and core values

EST3 is a high-end life safety and emergency communication platform under Edwards (UTC Fire&Security), focusing on * * Survivable * *, which can be integrated into one system:

Fire alarm control

security surveillance

Large scale emergency notification/emergency broadcast (MNEC)

Advantages: Share resources, reduce costs, simplify deployment, and replace multi system discrete networking.

Core Technology and Architecture Highlights

Distributed intelligence=high survivability

Network single point disconnection/short circuit can automatically isolate faults without affecting the operation of the entire network

Automatically split subnets in case of multiple failures, offline cabinets still work independently

Truly achieving continuous network failures and uninterrupted downtime even when the network is disconnected

High performance network capability

Key project values

Supports 64 network nodes

The maximum number of devices per node is 2500

The maximum total length of the network is 300000 feet (≈ 60 miles)

Communication protocol multi priority peer-to-peer token ring network

Response speed: Fast alarm response across the entire network

Powerful Audio Broadcasting System (EST3 Audio)

A single twisted pair cable can simultaneously transmit 8 voice messages

Program automatic partition broadcasting

Unified integration of security prompts and fire broadcasting

It is the core of the EST3 Sixty large-scale emergency broadcast plan

Hardware Structure and Easy to Use Design

Modular rail architecture: Plug and play expansion function module

Hinged display screen: convenient for wiring and maintenance

Quick snap fastener fixation: efficient installation

Detachable terminal block: easy to maintain

Each power supply is equipped with 2 channels of 3.5A auxiliary outputs

1 set of 24V batteries can backup up to 4 power sources

Human computer interaction and operation

The main interface prioritizes displaying the latest/earliest alarms and is not overwhelmed by low priority information

Fire telephone: synchronized display of incoming/connected status on the large screen, menu based operation

Paging microphone: can manually call out+trigger pre recorded voice+signal tone

Full graphic design, menu driven, no need for complex dip switches

Retrofit advantage

Support Signature Series intelligent smoke/security devices

Compatible with existing wiring, significantly reducing material and labor costs for renovation

Multi sensor detectors adapt to complex fire scenarios

Maintenance and Diagnosis

Intelligent diagnostic software for rapid troubleshooting

Complete PC report library

Generate device connection topology diagram for easy completion and maintenance

Planned maintenance improves system availability

Certification and Standards

UL 2572 (the world's first large-scale emergency notification standard)

UL Fire Detection Certification

UL Security Certification

UL Signal System Certification

Typical application scenarios

Commercial buildings, hotels, venues, transportation hubs

Museums, landmark buildings, government agencies

New and old buildings, renovation and expansion projects

Key questions and answers

Question 1: In which technical aspects does the core "high survivability" of EST3 manifest?

Answer: The core lies in distributed intelligence and self-healing networks:

Single point line disconnection/short circuit can be automatically isolated without affecting system operation

Automatically partition subnets in case of multiple faults, and maintain communication outside the fault area

Local cabinets that are disconnected from the network still work completely independently

There is no single point of failure bottleneck in the entire network.

Question 2: What are the outstanding advantages of EST3's audio broadcasting system compared to traditional systems?

Answer: The biggest advantage is EST3 Audio multiplexing technology:

Only one pair of twisted pair cables can simultaneously play 8 different audio channels

Automatically zone and broadcast fire/security/notification information according to the program

Seamless integration with the emergency broadcasting system EST3-Sixty

Less wiring, stronger scalability, and faster response.

Question 3: Why does EST3 have significant advantages in retrofit projects?

answer:

Support Signature Series intelligent detectors, compatible with dual applications of fire protection and security

It can directly utilize the old and existing wiring, greatly saving materials and labor

Modular and software programmable, capable of flexibly matching old system functions

Equipment diagnosis and topology mapping tools reduce the difficulty of later maintenance.
