Hand-Crank Emergency Sirens | LK Series
Hand-operated sirens that sound by turning a crank, without an electrical supply. The LK catalogue shows handheld and larger supported designs, with different materials, weights and sound ratings for each group.
Specifications
Product Overview
An LK hand-crank siren produces an audible warning through manual rotation rather than a battery or mains-powered motor. The catalogue shows the LK-100 family, an ABS LK-100P version and larger LK-120-family designs. These are not equivalent in size or weight: the image lists 1.2kg for the LK-100 group, 0.6kg for LK-100P and 9kg for the larger group. Select the carrying and support arrangement according to the task. The larger group's model labels differ between the drawing and table, so its suffix must be confirmed when ordering. The source's claimed coverage diameter is not a guaranteed warning radius or a substitute for an on-site audibility assessment.
Key Features
- Operates without batteries or mains electricity

Frequently Asked Questions
Does the siren use a push button or a crank?+
The product description and pictures show a hand crank. The source introduction's push-button description is inconsistent and is not used here.
Are all models aluminum and lightweight?+
No. The image lists an ABS LK-100P at 0.6kg, an aluminum-alloy LK-100 group at 1.2kg, and a larger group at 9kg. Choose a model instead of treating the listing as one size.
Does the 1.5km statement guarantee a 1.5km radius?+
No. The old text says up to 1.5km in diameter and provides no test conditions or model mapping. Actual audibility must be assessed for the operating speed, background noise and location.
Which larger LK-120 suffix should I order?+
The image labels include LK-120, LK-120A and LK-120S, while the table includes LK-120B. Send the required support-style picture so the exact suffix and specification can be checked.
What is needed for a quotation?+
Specify the model or reference picture, carrying arrangement, quantity and required documents. Sample availability, packing and current lead time are confirmed individually.
Applications
Manual signaling at camps and remote work locations where an electrical supply is unavailable. Select the actual model and assess local sound coverage; no all-weather or life-saving performance guarantee is made.
