4 Wire 12V/24V 220V Smoke Alarm Detector with Relay No/Nc Output for Fire Alarm System

Introduction4-Wire smoke alarm with relay output is common used for industrial control equipment, power cubicle, charging pile, alarm bell etc fire warning system. This smoke alarm has the characteristics of high sensitivity, stability and reliability, small power consumption and durability. Easy to install.Parameters  Product Namesmoke detector with relay outputRated operational voltageDC12~24V/220VSound pressure level≥85dbStatic current≤300uAAlarm current≤90mAWork temperature-10°C~+50°COutputSound&light alarm, relay outputHumidity≤95%.Product standard GB4715-2005,CEDimensionΦ105mm,H50mmFunctions1. Detection. Press detection button, it can fully check the alarm functions. And the alarm light  flashes quickly with a rapid sound.2. Alarm. In the normal environment, The alarm will flash automatically every 10S and              automatically detects the concentration of smoke in the surrounding environment at regular intervals(around 1.6s),If the smoke concentration is close to the alarm value, the alarm starts to perform intelligent calculation, and the alarm indicator light starts to flash. If the calculation result reaches or exceeds the alarm value, the alarm will start the sound-light alarm and start the relay. When the ambient smoke concentration drops below the alarm value, the alarm will automatically return to the normal working state.3. Output.Passive contact output. Contact capacity 24V/1A, NC or NO two kinds of output.InstallationFirst drill two mounting holes with a diameter of 5mm on the ceiling 43~ 62.5mm apart. Fix the alarm base with the plug and screw. Then connect the power line and output line.install the alarm to the base in the correct direction. Press down and tighten clockwise, finally turn on the power, it works.Product rangeAddressable fire alarm systemWireless alarm systemElectrical fire monitor systemExtinguishing control systemFire door monitor systemStandalone smoke detectors and combustible gas detector4-wire smoke detectors with relay output.Service1.
