Smoke detector is a common fire protection device which is able to sense the smoke in the early stage of fire and thus provide early warnings to people promptly. Smoke detector also hastens a lot of demand for the smoke detector magnetic mount.

Classification and Basic Principle of Smoke Detector

Generally, fire development process can be the initial stage, development stage and attenuation stage. The common principle of the smoke detector is to avoid the fire through the smoke concentration detection. The production of smoke is earlier than visible and invisible light when substance burns, and smoke detector can capture the early signals of fire, then signals will be transmitted to the controller of automatic fire alarm system after converted into electrical signals.

Smoke detector can be divided into ionization type and photoelectric type. For ionization smoke detector, positive and negative ions producing by ionization of Am-241 source will move towards the positive and negative electrode respectively under the action of the electronic field. Under normal conditions, current and voltage of both internal and external ionization chamber are stable, but these two electrical parameters would be changed when smoke enter into the external ionization chamber, then undermine the balance between internal and external ionization chamfer, thus detector will transmit the alarm messages. Photoelectric smoke detector is composed of light source, photoelectric element and electronic switch. The light emitted by luminous element will pass to the photosensitive element and circuit maintain normal work. The smoke will remarkably weaken the received light on photosensitive element and then detector will send out alarm due to the current variation.

About Smoke Detector Magnetic Mount

SDM Magnetic can provide smoke detector magnetic mount with different size and attractive force which suits all standard sized smoke detector and also offer relatively quick and easy alternative to traditional screws and plugs.
