WELS WSD 813-2/L Photoelectric Smoke Detector with Base

WELS WSD 813-2/L Photoelectric Smoke Detector with Base The WELS WSD 813-2/L is a very accurate photoelectric smoke detector that is made for use in businesses and factories to find fires early. It uses cutting-edge optical sensor technology to find visible particles made by smoldering fires far faster than ionization alarms. This sensor comes with its own mounting base, which makes sure that it is installed securely and smoothly into existing fire alarm control panels. Its strong design and low profile look make it a great choice for current safety systems. Feature Specification Detection Method Photoelectric (Optical) Operating Voltage 9V DC to 28V DC (Non-polarized) Standby Current ≤ 60μA Alarm Current 10mA to 50mA Sensitivity 0.15dB/m (±0.03dB/m) Operating Temperature -10°C to 55°C Humidity Range 0% to 95% RH (Non-condensing) Material Flame-retardant ABS Plastic Features: 1) Photoelectric sensor technology is very good at picking up smoldering flames but not so much cooking or steam alarms. 2) Integrated Mounting Base: The twist-lock base makes it easier to wire and keep up with. 3) You can see the status (Normal/Alarm) clearly from any angle thanks to the two LEDs. 4) Low Standby Current: Made to use less power in big fire alarm loops. 5) Strong Construction: The housing is made to last and can take hits, so it will be reliable for a long period in an industrial context. 6) Easy to Test: It has a magnetic or recessed test point that makes it easy to check that it works.   Applications Commercial offices: safe for open-plan workspaces and server rooms. Manufacturing Plants: Finding them in buildings with high ceilings or a lot of electrical equipment. Logistics and warehousing are vital for keeping an eye on big places where things are stored and moved. Hospitality: Fire safety is the responsibility of the hotel, resort, or restaurant. Safety insurance covers schools, libraries, and labs.
