Smoke Detector Wired Fire Alarming Sensor for Domestic Commercial LED Indicator 9‑24V

Feature: 1. This sensor is networking output with LED indication alarm and buzzer sound alarm made by SMT craftsmanship, which has strong stability. 2. This is wired networking and full alert, which can be linked to the building intercom system or security alarm system, etc. 3. There is 9 24V non‑polar wide voltage input (AC, DC), metal shielding and anti‑radio frequency interference (20V m‑1GHz). 4. This smoke detector has a special design of preventing the dust, insect and white light interference. It is clean and effective. 5. Sensors can guard the detecting safety of a variety of places: homes, warehouses, hotels, shopping malls, companies, restaurants, corridors, etc. Specification: Item Type: Photoelectric Smoke Sensor.Material: ABS Uses: Warehouses, Kitchens, Factories, Corridors, Supermarkets and Others Working Voltage: AC DC 9V 24V Standby Current: 16mA (Relay Normally Closed), 3mA (Relay Normally Open) Alarm Current: 8mA (Relay Normally Closed), 19mA (Relay Normally Open) Alarm Indication: Red Led is Always On Communication Method: Networking Detection Angle: 360 degrees Working Temperature: Approx. 10 celsius +50 celsius Ambient Temperature; Maximum 95percent H (No Condensation)Anti RF Interference: 10MHz 1GHz 20V m Package List: 1 x Smoke Detector1 x Manual Note: 1. The detector should be protected from dust, and the dust cover must be taken off after the project is officially put into use. 2. There should be no obstructions within 0.5m 19.7in around the detector.3.The horizontal distance between the detector and the air supply hole of the air conditioner should not be less than 1.5m 59.1in.4. The horizontal distance between the detector and the wall and the side of the beam should not be less than 0.5m 19.7in.5. When the detector is installed on the ceiling of the inner walkway with a width less than 3m 118.1in, it should be arranged in the center. The installation spacing of the detectors should not exceed 15m, and the distance between the detectors and the end wall should not be greater than half of the installation spacing of the detectors.6. The detector should be installed horizontally. If it must be installed obliquely, the inclination angle should not be greater than 45 degrees.7. The base of the detector should be installed firmly and its wire connection must be reliable.8. It is recommended to conduct a simulated fire alarm test every six months to test whether the detector is working properly.
