smoke detector

Product Overview

The networked smoke detector (hereinafter referred to as the detector) is suitable for fire prediction and alarm in places such as electricity, petrochemicals, homes, and warehouses. The detector has the characteristics of high sensitivity, stability and reliability, low power consumption, beauty and durability, and easy use, and can be used in conjunction with security systems.

Feature Introduction

Self inspection:Press the detection button, and the detector LED will remain on while emitting an alarm sound (note: self-test only checks the internal functions of the detector itself, and there is no relay signal output during self-test).

Work:Under normal circumstances, the detector's indicator light will flash approximately every 6 seconds. The detector automatically detects the smoke concentration in the surrounding environment and compensates for sensitivity based on the usage environment conditions. When the smoke concentration approaches the alarm value, the detector accelerates the intelligent calculation of the smoke concentration trend, and the alarm indicator light starts to flash. If the calculation result reaches or exceeds the alarm value, the detector will start an audible and visual alarm and activate the relay output. When the smoke concentration in the surrounding environment decreases toWhen the alarm value is below, the detector automatically returns to normal working condition.

Output: Passive contact output;The contact capacity is 24V/1A, which can be set as normally open or normally closed contact output through the jumper inside the detector. At the factory, the jumper wire is set to normally closed contacts by default.
