TAKENAKA ENGINEERING 火焰感測器 FS-3500 FS-3500

Feature

• It detects ultraviolet rays contained in the flame, so it works the moment a small flame comes out and outputs an alarm before a fire occurs.
• The 2-way power supply system, consisting of an external power supply (10 V to 30 V DC) and batteries (2 AA alkaline batteries and dedicated lithium batteries), allows you to select the power supply according to your application and location.
• It has a built-in alarm function to let you know when the battery is dead.
• When a flame is detected, the built-in buzzer sounds and the external output (non-voltage relay contact) can be taken out, so it can be connected to a remote disaster prevention controller.
