Wired smoke detector fire alarm sensor with LED indicator for home and commercial use, 9-24V

Features:

1. This sensor is a network output with an LED indicator alarm and a buzzer alarm, manufactured using SMT technology, which ensures high stability.

2. It is a wired network and comprehensive alert system, which can be connected to a building's intercom system or security alarm system, etc. 3. It has a wide non-polarized voltage input of 9-24V (AC, DC), metal shielding, and anti-radio frequency interference (20V/m-1GHz). 4. This smoke detector has a special design to prevent interference from dust, insects, and white light. It is clean and efficient. 5. The sensors can protect the detection safety of a variety of places: homes, warehouses, hotels, shopping malls, businesses, restaurants, corridors, etc.

Specifications:

Item Type: Photoelectric Smoke Sensor Material: ABS Uses: Warehouses, kitchens, factories, corridors, supermarkets, and others Operating 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: Network Detection Angle: 360° Operating Temperature: Approx. -10℃-+50℃ Ambient Temperature; Maximum 95% RH (non-condensing) RF interference suppression: 10 MHz-1 GHz 20 V/m

How to use:

1. Choose a suitable installation location and generally install it on the ceiling in the center of the detector's coverage area. 2. Connect the power supply and signal lines to the mounting base (mounting base "1" and "2" are non-polarity power inputs; "3" and "4" are alarm output contacts). 3. Description of the two-position red dial switch: The number 2 on the red dial corresponds to the KT control switch. The number "1" on the red DIP switch corresponds to the RST control switch. KT alarm output parameters: When the KT switch is turned in the "ON" direction, the relay is normally open. When the KT switch is set to the "2" direction, the relay is normally closed. RST Alarm Mode: When the RST switch is turned towards the "ON" position, the power-off function is reset. When the RST switch is turned towards the "1" position, it resets automatically. Package List: 1 x Smoke Detector 1 x Manual Note: 1. The detector must be protected from dust, and the dust cover must be removed after the project's official commissioning. 2. There must be no obstructions within 0.5 m / 19.7 inches of the detector. 3. The horizontal distance between the detector and the air conditioner's air supply vent must be at least 1.5 m / 59.1 inches. 4. The horizontal distance between the detector and the wall and the beam's edge must be at least 0.5 m / 19.7 inches. When the detector is installed in the ceiling of an interior walkway less than 3 m / 118.1 inches wide, it must be centered. The installation spacing of detectors must not exceed 15 m, and the distance between the detectors and the end wall must not exceed half the detector installation spacing. 6. The detector must be installed horizontally. If it must be installed at an angle, the angle of inclination must not exceed 45 degrees. 7. The detector base must be securely installed, and its wired connection must be reliable. 8. It is recommended to perform a simulated fire alarm test every six months to verify that the detector is functioning correctly.
