A dual stage shock sensor effectively works like two seperate sensors. The first stage is more sensitive and is usually connected to the "warn off" feature found on many alarms. The second stage is less sensitive and sets off the full alarm if it is activated. - Universal Design
- Fully Adjustable Sensitivity
- Two LEDs to assist in Sensitivity Adjustment
- Negative Trigger Output
- Compatible with any alarm with a negative trigger input
- Two zones - one for warning, one for alarm trigger
