PK-20A35EW-24VQ

Alarms, Buzzers, and Sirens

Alarms, buzzers, and sirens are all safety devices that alert people to a potential danger that is present. They are used in a variety of situations, from burglar alarms to fire alarms, and have been around for centuries. The most common type of alarm is the PK-20A35EW-24VQ, and its application field and working principle are essential to understanding how these devices work.

Application Field

The PK-20A35EW-24VQ is a 24VQ commercial grade smoke detector and air sampling smoke detector. It is designed for use in commercial or industrial applications and has a wide range of application fields, including merchandising areas, warehouses, restaurants, offices, cleanrooms, and any other area where an early warning of a fire danger is important. This alarm can also be used in area-wide smoke detection systems, where sensors provide a signal when smoke is detected from any source.

In addition to smoke detection, the PK-20A35EW-24VQ can also be used to detect carbon monoxide and other dangerous gases. This makes it useful for all types of applications where the presence of these gases could present a hazard. Carbon monoxide detectors are usually installed in rooms where such gases are known to be present or where a gas appliance is being used, such as a boiler, water heater, or even a stove.

Working Principle

The PK-20A35EW-24VQ works by using a combination of optical and ionization technology to detect smoke. This is done through an optical chamber and an ionization chamber, which are both connected to the alarm. When a smoke particle enters the optical chamber, it is detected by the alarm and an alarm is triggered. The ionization chamber works similarly, sensing particles based on their ionic charge and triggering an alarm if a certain threshold is surpassed.

The PK-20A35EW-24VQ is designed to be an efficient smoke detector. It is equipped with a dust filter that helps to prevent false alarms due to dust accumulation. The alarm also features a tolerance of high humidity, which means it will still function even in damp environments. The alarm also has a failsafe feature that will cause the alarm to turn off in the event of a power failure.

In addition to the smoke detection capabilities, the PK-20A35EW-24VQ also features a carbon monoxide detection system. This uses a chemical sensing element to detect the presence of carbon monoxide in the air. This system works by sensing changes in the concentration of carbon monoxide in the air, and will trigger an alarm if the concentration becomes too high.

The PK-20A35EW-24VQ is designed to provide an effective early warning system for fires and carbon monoxide poisoning. Its application field is broad and it can be used in a variety of places to detect fire dangers and other hazardous gases. Its working principle is also straightforward and effective, ensuring that it will always be dependable in an emergency situation.
