Newmicroprocessorsandchipsetstakefull advantage ofthelatestadvancesincomputingtechnology, leading to smarter, faster, higher-capacity processing and more ef- ficient designs. EST3X’s patented Voltage BoostTM tech- nology, for example, delivers consistent voltage – even

at low battery power – resulting in lighter cable require- ments and/or longer runs. That saves time and money.

High performance processing also leads to powerful net- working features and versatile digital audio functionality. The wide range of EST3X configurations include stand- alone operation, networking with up to eight nodes, or integration with an EST3 network comprising as many as 64 nodes — complete with mass notification capabilities and display of security events.

EST3 is a modular control platform uniquely designed to meet the needs of applications ranging from standalone single panel fire alarm systems to multi-panel networks with unified fire alarm, security, access control and Mass Notification functions. Each function uses many of the same components, simplifying system layouts.

Virtually all EST3 operating features are software-controlled. A powerful System Definition Utility program helps define system operations in a fraction of the time required by previous meth- ods. This gives EST3 great site flexibility and ensures operational changes and upgrades will be possible years after the initial instal- lation.

EST3 is uniquely designed to meet the life safety needs of any size facility. The function of each panel can be customized by using an extensive selection of plug and play local rail modules.

With support for 64 nodes of up to 2,500 devices each, this network’s multi-priority peer-to-peer token ring protocol delivers a fast alarm response time across any size network. Add to that the ability to network panels with fiber or copper connections with an overall length of 160000 ft - that’s 30 miles - and you’ve got virtu- ally unlimited networking options.

This card gives an SFS1-CPU main board the ability to network up to 64 nodes on an EST3 network Supports Class B and Class A wiring Provides two independent RS 485 circuits: one for network data communications and one for digital audio communications

The Edwards SIGS-SD Duct Smoke Detector is an intelligent, addressable device designed to monitor airflow in HVAC ducts for smoke particles. It ensures early detection of smoke within air-handling systems, preventing the spread of smoke through ventilation ducts in commercial and industrial facilities.

Description:
The Edwards SIGS-SD detector combines advanced photoelectric smoke sensing with a rugged duct housing for dependable operation in air ducts and ventilation systems.
It continuously samples airflow through an integral sampling tube, analyzing smoke levels using its intelligent sensing chamber.

Equipped with an addressable sensor, this detector communicates directly with the fire-alarm control panel for real-time monitoring and fault supervision. It helps trigger air-handling shutdown or damper operation to contain smoke movement during an emergency.
Compact, durable, and easy to install, the SIGS-SD offers reliability and precision trusted by consultants, integrators, and safety professionals across India.

Applications:

• HVAC and ventilation ducts in commercial buildings

• Industrial air-handling and process ventilation systems

• Hospitals, hotels, data centers, and clean rooms

• Warehouses, malls, and large office complexes

Key Features:

• Intelligent addressable duct smoke detector

• Photoelectric sensing technology for reliable smoke detection

• Compatible with Edwards Signature Series panels

• Integral sampling tube and cover for efficient airflow monitoring

• Built-in status LEDs (Green – Normal, Red – Alarm)

• Optional remote test and indicator capability

• Rugged housing for duct mounting (horizontal or vertical)

• Easy installation and maintenance design

• UL and EN-54 compliant for performance and safety

Technical Specifications:

• Operating Voltage: 15 – 20 V DC (loop powered)

• Air Velocity Range: 0.5 – 20.0 m/s

• Operating Temperature: 0 °C – 38 °C

• Humidity: Up to 93 % RH (non-condensing)

• Sensing Method: Photoelectric light scatter

• Mounting: Directly on duct surface with sampling tubes

• Construction: Flame-retardant polymer housing
