Alarm Modes and Features
4-in-1 Functionality
The NineLeaf alarm integrates multiple functions for comprehensive vehicle security and safety:
- Anti-Theft Alarm: Deters thieves with a loud 110dB alarm triggered by vibration.
- Brake Alarm: Automatically activates a warning light and sound when braking.
- Bicycle Bell: Functions as a horn for signaling.
- Tail Light: Provides rear visibility with various lighting modes.
Intelligent Auto ON/OFF
In intelligent mode, the alarm unit automatically adjusts its operation based on ambient light and motion:
- In dark conditions, if the device stops for more than 30 seconds, it will automatically turn off to conserve power.
- When motion is detected again, the device will automatically turn on.
Brake Alarm Function
The integrated brake sensor detects when you are braking or slowing down. Upon detection, the tail light will immediately turn on brightly for 2 seconds to warn other road users. This feature significantly enhances safety, especially during night rides or in tunnels.

Vibration Alarm and Sensitivity
When armed, the alarm unit will emit a loud 110dB sound if it detects vibrations, effectively deterring potential thieves. The sensitivity of the vibration detection can be adjusted to 7 levels (from Duo to Xi, corresponding to 7 levels) to suit your environment and preferences, minimizing false alarms while ensuring effective protection.
Adjustable Alarm Volume
The alarm offers 3 adjustable volume levels for its bell and alarm sounds, allowing you to choose the appropriate loudness for different situations.

- Breathing (Auto ON/OFF): A pulsating light effect that also features automatic ON/OFF based on inactivity and motion in dark conditions.
