JTY-GD-HA821Inverter Smoke Sensor/Energy Storage Cabinet Smoke Sensor/Distribution Box Smoke Alarm

I. Product Overview:

This product is a photoelectric smoke concentration detector, which operates based on the principle of sensing smoke particles. It adopts a unique structural design and photoelectric signal processing technology, featuring functions such as dust resistance, insect resistance, and immunity to external light interference, ensuring product stability from the design perspective. This product responds well to visible smoke produced by slow smoldering or open flames. It is suitable for smoke monitoring in indoor environments such as box transformers, cabinets, substations, wind power systems, enclosures, and warehouses.

II. Features:

This detector is non-addressable and operates directly when connected to a DC power supply. During normal operation, the indicator light flashes. When an alarm is triggered, the alarm indicator light turns on. The detector has a pair of output contacts that close/open after an alarm. It requires power-off/automatic reset after the smoke clears. The detector uses a base with a unique installation method. ● Power-off/automatic reset optional ● Infrared photoelectric sensor ● Intelligent logic control to filter out false alarms ● Normally open/normally closed (NO/NC) alarm output ● Network output/LED alarm indication ● SMT manufacturing process for strong stability ● Dust-proof, insect-proof, and anti-white light interference design ● Compliance standard: GB4715-2005, 57-7

III. Technical Parameters:

Operating voltage: DC48V Sensitivity: 0.1-0.3dB/m Standby current: 14mA (relay normally closed) 4mA (relay normally open) Alarm current: 9mA (relay normally closed) 19mA (relay normally open) Alarm indication: Red LED constantly on Sensor: Infrared photoelectric sensor Operating temperature: -10℃ to +50℃ Environmental humidity: Max 95%RH (no condensation) RF interference resistance: 10MHz to 1GHz 20V/m Alarm output: Normally open/normally closed, contact DC28V 100mA Coverage area: When the space height is 6m to 12m, the protection area of one detector is 80m2 for general protection sites. When the space height is below 6m, the protection area is 60m2. Specific parameters should comply with the Code for Design of Automatic Fire Alarm Systems GB 50116-98. Sensitivity level: Level 1 Dimensions: 100mm (diameter) * 48mm (height)
