Available in optional activations. The HiSens version is ideal for panic alarm situations where it is desirable that any contact with the strip, for example, even when someone is pushed into it, causes an alarm.

If a great deal of accidental contact is envisaged, which would cause nuisance tripping of the alarm, the LoSens version may be more appropriate, since this a more deliberate operation.

The only difference between the two systems is that the HiSens uses a higher, black ribbon switch and the LoSens uses a lower, white ribbon switch.
