FIRE SMOKE DETECTORS

A fire or smoke detector in a fire alarm system warns people when smoke, fire, carbon monoxide, or other fire-related emergencies are detected. These detectors may be activated automatically from smoke detectors and heat detectors or may also be activated via manual fire alarm activation devices such as manual call points or pull stations. Alarms can be either motorized bells or wall mountable sounders or horns. They can also be speaker strobes that sound an alarm, followed by a voice evacuation message which warns people inside the building not to use the elevators. Fire detectors play a significant role in saving lives and we feel proud of being manufacturers of Fire detectors and many advanced devices in Fire alarm systems that save human life.

Smoke Detector

• • Operating voltage range : 9 to 32 VDC Volts Non – polarized
• • Operating temprature Range : 14oF to 120oF (-10oC to 49oC )
• • Diameter : 4.0″ (103mm)
• • Alarm Detector : Dual Red LEDs

Heat Detector

• Operating voltage range : 9 to 32 VDC Volts Non – polarized
• Operating temprature Range : 14oF to 120oF (-10oC to 49oC )
• Diameter : 4.0″ (103mm).
• Thermistor Temprature : 68oC

BEAM DETECTORS

Beam detectors are specialized fire detection devices that use infrared beams to detect the presence of smoke. These detectors are particularly useful in spacious areas, open rooms, and buildings with high ceilings. Let’s explore more about them:

Reflected Beam Smoke Detectors by Honeywell System Sensor:

• • These detectors are designed to provide reliable smoke detection for large spaces.
• • They consist of a single-ended reflective design, making installation easier than dual-ended projected beam detectors.
• • Alignment is accomplished via an optical sight and a signal strength meter.
• • The BEAM1224 model operates in temperatures ranging from -22°F to 131°F.
• • It offers 16 to 328 feet of protection range and has user-selectable sensitivity levels.
• • Applications include warehouses, atriums, arenas, and spacious rooms1.

Principle of Beam Detection:

• Beam detection, also known as beam smoke detection, relies on directing a light beam between an emitter and a receiver.
• When smoke particles enter the path of the beam, they scatter the light, triggering an alarm signal.
Working Principle:
• A beam detector consists of two main parts :
• Source : This can be an IR LED, laser, or other light-emitting components.
• Detection : Typically a photodiode.
• The detector projects a beam of light across large areas, detecting smoke as an indicator of fire.
• These detectors are especially useful where other smoke detection methods are challenging to install or maintain.
• In summary, beam detectors play a crucial role in fire safety, providing early warning in expansive spaces.

BATTERY OPERATED SMOKE DETECTORS

Battery-operated smoke detectors are essential safety devices that provide early warning in case of a fire. Here are some details about them:

Features:

• • Plug and Play : No need for professional installation support.
• • Cable and Wire-Free : Avoid the hassle of following up with electricians or installers.
• • Inbuilt Alarm Buzzer : Notifies occupants during fire emergencies, aiding evacuation.
• • Low Operating Cost : Requires only 2 AAA batteries.
• • Versatile Use : Suitable for homes, offices, and stores.

Specification:

• Dimensions : 12D x 23W x 23H millimeters.
• Operating Humidity : Plug and play – no installation support needed.
• Upper Temperature Rating : Up to 55°C.
• Sensor Type : Smoke detector.
• Detection Capability : Detects smoke instantly, even at an incipient stage, reducing potential damages from fire outbreaks.
• Provides visual and audio alarms.
• Warns when the battery is low.
• Where to Use : Install it anywhere – homes, offices, stores, etc.
• Battery-powered smoke alarms are popular for their cost-effectiveness and ease of installation.
• They operate independently of the home’s electrical system, ensuring functionality even during power cuts.
