Conventional Fire Alarm Systems

 

Nittan Fire Alarm Equipment:

Control Panel

Nittan products supported by highly advanced technologies, utilizing microcomputer control for the breathtaking security system. With the features brought us the sophisticated function and high reliabilities. The parts are supplied in unit assembly, which has led to variety of fire protection requirements doubled by versatile fire detection features, flexible service ability and automatic inspection functions.

The control panel is equipped with an "Alarm Delay" function which gives a much greater degree of protection against false alarms.

Photoelectric Smoke Detector

Model 2KH2 Photoelectric Smoke Detector is of a low profile and employs state of the arts Surface Mount Technology. The principle and functions of the 2KH2 have been widely accepted in the worldwide market for a long time. It is most suitable for such modern buildings as employed in the design of decorative smooth ceilings.

Rate Of Rise Heat Detector

Sensing the rapid or abnormal rise in temperature of ambient air.

Fixed Heat Detector

Activate whenever the ambient air temperature reaches the top temperature detector setting.

Flame  Detector 

It's used principally in area considered to be of high risk where naked lights could be danger i.e. storage of flammable liquid.

   Beam Type Detector

Beam smoke detectors generally have a maximum range of 330 feet and a minimum distance of 60 feet. They are ideally suited for height ceiling applications.

* Manual Alarm Station

 

II. Addressable Fire Alarm Systems

Analogue Addressable Fire Alarm Systems differ from conventional systems in a number of ways and certainly add more flexibility, intelligence, speed of identification and scope of control. For this reason Analogue Addressable Fire Alarm Systems are the natural choice for larger premises and more complex system requirements.

Addressable Fire Alarm Systems

conventional fire alarm arrangement

In an analogue addressable system, detectors are wired in a loop around the building with each detector having its own unique 'address'. The system may contain one or more loops depending upon the size of the system and design requirements. The Fire Control Panel 'communicates' with each detector individually and receives a status report e.g. Healthy, In Alarm or In Fault etc. 

Highly advanced microcomputer technologies & data communication technique are successfully combined in the intelligent type fire protection systems, achieving disaster supervision and control - on a small or large scale - ensuring that the occupants' safety requirements are met.

LCD Display:

A simple menu system is featured with the LCD display improved visibility & operation of the NF5 system ...

A multi-function CRT can be connected to the LFNet via the interface panel for CRT.

 

  Use of analogue sensors

NF5 features an alarm processing facility that uses preset levels to distinguish between pre-alarm and fire alarm signal. A self-diagnostic feature provides continuous automatic monitoring of deterioration of detector sensitivity or disconnection.

It's used principally in area considered to be of high risk where naked lights could be danger i.e. storage of flammable liquid.

Conventional fire detectors and/or addressable analogue fire detectors available.

 Communication System

The LFNet communication system facilities system structuring. Each device are connected to the LFNet line via the interface (NodeCard). The LFNet line is of the dual wiring type which means that even if one of the cables is subjected to a disconnection or short cuircuit, the system will continue to function as intended.

 

III. Gas Alarm Systems

Riken gas products

The use of LPG or CH4 (Methane) is common for cooking and heating in most homes unless electricity is used for such purposes.

If properly handled, these gases are considered to be safe. However, if misused, they become potentially dangerous to house owners.

An accumulation of leaks in the fuel lines or outlets can create a flammable or explosive hazard.

The gas detector designed to protect home owners from the danger of gas leak. It continuously monitor and automatically provides visual and audible alarms for explosive hazardous levels of gas. If gas leak is persist, the gas detector triggers the output signal.

 

Gas Alarm System use for industrial fields 

 

The gas alarm system with multi-functions responds to the customer's diverse needs, which is LP gas detection/alarm for monitoring gas leakage out of manufacture, storage and consumption facilities of LPG and for prevention from an accident due to gas leak. 

 

 CO detector & control panel

 COsensor is a microprocessed electronic system from COFEM, capable of detecting and measuring the presence of carbon monoxide in closed sites (car park, workshop, tunnel, etc.) and controlling a fume extractor and/or activating an alarm when a reset concentration of CO occurs.

On the COsensor monoxide detection system, the detectors are supplied and communicated with the control panel per zone.
