External Signal Trigger
The SLA-01HK is triggered by an external switch signal instead of a built-in sensor. It is suitable for PLCs, relays, security cameras and automation control systems.
Dry or Wet Contact Input
Users can choose a passive signal dry contact version or an active signal wet contact version. Confirm the output type of your device before ordering to avoid signal mismatch.
120dB Adjustable Siren
The siren provides 0–120dB adjustable sound output. The rotary knob allows volume adjustment for quiet offices, warehouses or noisy workshops.
LED Strobe Warning
The LED strobe light works together with the siren sound to provide audible and visual warning after the alarm receives a trigger signal.
IP65 Steel Housing
The cold-rolled steel housing supports industrial use with IP65 dustproof and waterproof protection. Wall mounting is suitable for fixed warning points.
