Overview

High-sensitivity smart smoke detector has ultra-high precision 360° detection and the alarm decibel is higher than 80db. Battery backup ensures uninterrupted operation during power outages, making this detector ideal for enhancing safety in homes, offices, and commercial spaces.

Smoke and temperature dual detection

Dual detection enables the smoke detector to sense both smoke and rapid temperature increases, providing quicker and more accurate alerts in the early stages of a fire.
By combining smoke and temperature data, the wired smoke detector can more accurately identify genuine fire hazards, minimizing false alarms from harmless smoke or heat sources.
This dual feature allows the detector to respond effectively to different types of fires, from smoldering fires that produce more smoke to fast-spreading ones with intense heat.
With both smoke and temperature sensitivity, the detector provides comprehensive monitoring, making it ideal for high-risk areas where early detection is crucial.

85db high decibel alarm within 3 meters

The high-decibel alarm ensures that occupants within close range are promptly alerted to potential dangers, enhancing immediate awareness in emergency situations.
The 85dB sound level effectively cuts through background noise, making it suitable for busier areas like warehouses, workshops, and commercial spaces.
The loud alarm within a 3-meter radius helps direct attention precisely where it’s needed, allowing people nearby to react quickly and take immediate action.
This powerful alarm meets high standards for audibility, providing clear and unmistakable alerts that support compliance with safety regulations in various settings.

FAQs

Q1: What is a smoke detector?
A1: A smoke detector is a typical device converted from space fire protection measures to civilian use. The smoke detector mainly realizes fire prevention by monitoring the concentration of smoke. The smoke detector adopts ion-type smoke sensor. The ion-type smoke sensor is a kind of advanced technology, stable and reliable sensor, which is widely used in various daily life. Its performance is far better than that of gas-sensitive resistance fire alarms.

Q2: How does a smoke detector work?
A2: The infrared beam of the infrared emission tube is dispersed by the smoke particles, and the intensity of the scattered light is proportional to the smoke concentration. Therefore, the intensity of the infrared beam received by the photosensitive tube will change, and it will be converted into a point signal, which will eventually become an alarm signal.

Q3: What does a smoke detector do?
A3: Smoke detectors assemble sensors, control assemblies, and alarm notifications. Therefore, this is a collection of multi-functional detector in one, is the most suitable for residential. Once the smoke detector is triggered, the device sends a signal to the audio-visual notification device, which will issue an alarm. Inside the smoke detector, you'll find a power source and a built-in sensor that can react to the smoke in different ways.

Tips: Is a wired smoke detector interconnected?

Yes, wired smoke detectors can be interconnected. When they’re hardwired into the same circuit, an interconnected system allows all detectors to sound an alarm simultaneously if one detects smoke. This feature ensures that, regardless of where smoke is detected, everyone in the building is alerted, which is particularly helpful for large spaces or multi-floor buildings.

In most interconnected setups, pressing the test button on one detector will also trigger alarms across all units, making it easy to verify system functionality. Interconnected detectors are often required by building codes, especially in multi-level homes and commercial buildings, to enhance safety.
