T3 Omni-tilt Switch
Magnasphere's T3 Omni-Tilt switch is designed to sense horizontal inertial disturbance and tilt from its vertical position. The T3 can be wired directly to panels or used with wireless transmitters. Objects secured with the T3 Omni-Tilt won't tolerate movements such as jostling, loading, rolling, impact, tilt, or transit without providing an alarm signal. The Omni Tilt uses a magnetic latch to resist false alarms from light vibration.
