smoke detector, device used to warn occupants of a building of the presence of a fire before it reaches a rapidly spreading stage and inhibits escape or attempts to extinguish it. On sensing smoke the detectors emit a loud, high-pitched alarm tone, usually warbling or intermittent, and usually accompanied by a flashing light.

Types Of Smoke Detectors
There are two types of smoke Detectors:-
- Photoelectric Type Smoke Detector
- Ionization Type Smoke Detector
Smoke Detector Working Principal
Photoelectric Type Smoke Detector
A smoke sensor ‘s initial function is to detect smoke to warn occupants about fire presence. The way it senses the fire depends on the type of unit it is. A photoelectric model has a light source that shines into a sensing chamber containing a sensor. The light sits at an angle to the sensor. When smoke enters the chamber, it causes the light to reflect onto the sensor, triggering the alarm. These units are best at detecting smoldering fires that start with smoke before eventually breaking into flames.
Ionization Type Smoke Sensor
An ionization type smoke detector uses radioactive material positioned between two electrically charged plates to ionize the air inside it. This creates a current flow between the two plates. Smoke sets off the alarm when it disrupts the ion flow. These alarms are most responsive to fires with blazing flames.
Photoelectric and ionization type smoke detectors both have certain advantages that make them more effective in specific areas. For example, a photoelectric model quickly detects smoke from smoldering bedding or furniture in a bedroom, living room or family room, while ionization units give fast warning of a blaze triggered by flammables in a utility room or a stove fire in a kitchen. Because each type is ideal for a certain type of fire, it’s a good idea to have at least one of each in your home. You can also get a dual-sensing model that uses both photoelectric and ionization methods for detection.
Advantages Of Smoke Sensor
Properly installed and maintained smoke alarms are considered to be one of the best and least expensive means of providing an early warning of a potentially deadly fire and could reduce by almost half the risk of dying from a fire at your work premises or in your home.
