This ultra compact security system’s remote provides much greater range than other alarms. You can reliably monitor your bikes status farther away because this is the only remote alarm to use a dedicated high frequency FM channel. Selectable vibrate or audio modes and a backlit LCD screen with clear icons and text messages make it easy to use. The alarm’s microprocessor, transmitter, and state-of-the-art two axis accelerometer require no adjustments and all are hermetically sealed inside a small unit that can be mounted in any position. There is a ton of other features like ‘in-range sensor’, ‘ignition sensor’, ‘battery safeguard’, ‘anti-hijack module’ (really!), ‘ignition disable’ and selectable manual/auto arming. Even more than can be listed here. An easy to install, top quality, advance in alarm performance. 3"×1.5"×.5"
