A functioning business may have all it's necessary ingredients to make the business a success. However, failing to have the necessary fire safety could accidentally bring it all to an abrupt halt.

 
 

 
 
   
If waking up to a smoke alarm is your first line of defence against a potential fire hazard then you shouldnít hesitate to install one. Smoke detectors save thousands of lives each year and itís recommended that every home or building have one detector in each room on every floor

Ionisation smoke detection
 

Ionization is the condition of an element being disconnected into ions. An ionisation smoke detector consists of an ionization chamber which is connected to a negative terminal and a reference chamber which is connected to the positive terminal. The smoke detector uses a radioactive isotope such as americium-241 in the ionisation chamber to produce ionization known as alpha particles into the air. These alpha particles collide with air molecules and cause them to split into two halves - a positive ion and a negative ion. The positive ions get attracted to the negative chamber and the negative ions to the positive chamber thus creating an electric current in the air between the two chambers. If smoke particles pass between the chambers the ions will attach to the particles causing the current to flow difficultly. When the electric circuit detects the drop in current the alarm will be triggered.

Optical smoke detection
 

An optical smoke detector also known as a photoelectric alarm is a light sensor. The optical smoke detector uses a photodiode (sensor) and an infrared LED to detect smoke inside an optical chamber. The sensor is placed across the infrared LED to an angle so that the LED beam does not point directly at the photodiode. When smoke enters the chamber the LED beam reflects off small particles of smoke and directs it to the sensor thus triggering the alarm.

What is Optical smoke detection?

An optical smoke detector also known as a photoelectric alarm is a light sensor. The optical smoke detector uses a photodiode (sensor) and an infrared LED to detect smoke inside an optical chamber. The sensor is placed across the infrared LED to an angle so that the LED beam does not point directly at the photodiode. When smoke enters the chamber the LED beam reflects off small particles of smoke and directs it to the sensor thus triggering the alarm.

Benefits:
Photoelectric smoke detection is generally more responsive to fires that begin with a long period of smouldering (the beginning stage of fires) but may respond a bit slower to rapidly growing fires yet they are well balanced to spot both the smouldering and flaming stages of fires.

Installation:
Make sure the detector is functioning properly before installing it. The detector should be placed as close as possible to the centre of the ceiling. If ceiling mounting is not possible then the detector can be wall mounted 30 cm from the ceiling.

Description

The Series 65 optical smoke detectors are mainly used in environments such as offices or buildings where an electric power cable is present or capable of being installed.

The XP95 ionisation smoke detectors are mainly used in environments such as offices, medium sized buildings, large homes or restaurants where an electric power cable or fire security control system is present or capable of being installed.

A voltage signal is generated by a drop in the current flow from the two chambers inside the detector due to smoke interfering with the electric current caused by ionisation. The XP95 uses an electric circuitry to convert the analogue voltage signal to an electric digital signal which is then sent to the control system for processing. The control system assesses the signal and compares it to the systems data. When the control system determines that a fire exists it instructs the detector to switch on its LEDs and initiates the pre-planned alarm routine.

What is optical beam smoke detection?

Optical beam smoke detectors (OBSDs) work on the principle of light obscuration. The imaging detector uses the same technology as the optical detectors but with some differences. It uses ultra violet and/or infrared rays that are projected across a room to detect light scattering or absorbance.

Installation:
Of all the smoke detection equipment auto-aligning beam detectors probably have the quickest installation time which means saving time and money not to mention less disruption in the installation environment. OBSDs are preferably installed in high ceiling applications such as shopping malls and warehouses etc.

 
 
  Reflective beam smoke detector Optical beam imaging smoke detector
 
Description

The motorized beam detector makes use of a reflector where the beam from the unit is mirrored off of and extended for further reaches. With its fast motorization the optical beam detector can auto align itself in under 4 minutes and re-align itself in under 2 minutes. This new motorisation adds the benefit of reduced false alarms. With its new technology the reflective beam detector is a reliable and economical way to warn for fires in large areas that need fire protection.

The imaging (beam) detector uses the same technology as the optical detectors but with some differences. It uses multiple beams (one infrared beam and one ultra violet beam) that are projected across a room to detect light scattering or absorbance.

  Battery Operated Smoke Detectors Cigarette Smoke Detectors - Burning Cigarette Warning
 
Description

If swapping a smoke detectors flat battery is as simple as buying a new one and popping it in then donít hesitate doing it or risk facing the possibility of being caught in a fatal predicament.

The battery operated smoke detector alarm uses the ionisation technology to identify smoke particles in the air. The detector is mainly used in environments such as bedrooms, hallways, lounge rooms or even small building without a fire security system.

For some it could be hard to hold back the craving for a quick fag, unfortunate for those there are areas that donít allow for it. These none-smoking environments might not always be smoking proof but a special unit could be installed to warn for unwarranted smoking.

The SD Evolution incorporates flame, smoke and passive infrared (PIR) motion detection with a 120 degree field of view. It provides voice messages in any language and in any area and warns for unwarranted smoking in none-smoking areas. Special risks or hazards such as slips, trips and falls, infection control procedures, hygiene requirements, security monitoring or point of sale merchandising can also be picked up. The SD Evolution can be incorporated with multiple Cig-Arrete SD Evolution detectors that communicate wirelessly with each other to send the signal to an external voice sounder and strobe.

When the electric circuit detects the drop in current the alarm will be triggered.

What is passive infrared detection (PID)?

Passive infrared (PIR) also known as passive infrared detection (PID) is an electronic sensor that uses pyroelectric materials to measure light radiating from objects. PIDs use a sensor that detects the infrared radiation given off by people or other objects in its field of view without generating or radiating any energy or emitting any infrared beams itself. The PID device can detect motion by comparing one temperature such as a wall with another such as a human walking by. The device also differentiates the emitted infrared radiation between a human and the glowing flame of a cigarette.

The device should be placed in a position where it can view the area that needs to be monitored. It is important to know the deviceís range of view so that you can know where to place it in a given area. For larger areas, multiple interconnected detectors can be used.

Recommendations:

Donít get caught up in a fire hazard situation due to flat batteries. Replace the batteries at least once a year to ensure warning functionality. Thousands of people die each year from fires in their homes and the majority of them are from insufficient detectors installed. It is recommended to place at least one detector per room.
