NOTIFIER JTW-BD-FST-851C NFS2-3030 series fire alarm control panels

The NOTIFIER JTW-BD-FST-851C is a type of fixed temperature fire detector. Here is a detailed introduction:

General Description

The JTW-BD-FST-851C is designed to provide reliable fire detection by sensing changes in temperature. It is commonly used in various indoor environments to detect the occurrence of fires at an early stage.

Features

Fixed Temperature Sensing: It is equipped with a temperature - sensitive element that activates when the ambient temperature reaches a predetermined fixed temperature. This ensures accurate and consistent detection of fires, reducing the risk of false alarms.

Intelligent Design: The detector incorporates advanced microprocessor - based technology, which allows it to analyze the temperature data and distinguish between normal temperature fluctuations and actual fire - related temperature rises. It can adapt to different environmental conditions to some extent, improving the reliability of fire detection.

Addressable Functionality: Similar to other products in the NOTIFIER series, the JTW - BD - FST - 851C is addressable. It can be uniquely identified and monitored within a fire alarm system, enabling precise location of the detector in case of an alarm. This feature helps fire - fighting personnel quickly identify the location of the fire and take appropriate measures.

Self - Diagnosis and Monitoring: The detector continuously monitors its own internal components and operating conditions. It can detect any faults or malfunctions in the temperature - sensing element, circuitry, or power supply and report them to the fire alarm controller. This self - diagnosis function ensures the reliability and integrity of the fire alarm system.

Easy Installation and Maintenance: The JTW-BD-FST-851C is designed for easy installation. It usually comes with a standard mounting base that allows for quick and secure attachment to the ceiling or wall. Routine maintenance is also relatively simple, with accessible components for inspection and replacement if necessary.

Technical Specifications

Power Supply: It typically operates on a DC voltage within the range of 15 - 32 VDC. The detector draws a relatively low current, ensuring energy - efficient operation and compatibility with different power sources in the fire alarm system.

Sensitivity: The sensitivity of the JTW-BD-FST-851C is set to respond to a specific fixed temperature. The typical activation temperature is 68℃, but there may be different temperature settings available depending on the specific application requirements.

Response Time: The detector has a relatively fast response time once the set temperature is reached. It usually takes a few seconds to send out an alarm signal after the temperature exceeds the threshold, allowing for timely detection and response to the fire.

Environmental Conditions: It is designed to operate within a certain range of environmental conditions. The temperature range is usually - 10℃ to 55℃, and it can handle relative humidity levels from 10% to 95% non - condensing. This makes it suitable for use in various indoor locations, such as offices, warehouses, and residential buildings.

In summary, the NOTIFIER JTW-BD-FST-851C is a high - performance fixed temperature fire detector that offers reliable fire detection, advanced features, and easy integration into fire alarm systems. It plays an important role in enhancing the safety and protection of buildings and their occupants.
