The Superpass II is an automatic non-motion alarm with manually operated panic button.

The unit has an auto-on feature and activates when the accountability key is removed. The key can be provided with personal information and has an adjustable strap that can be used to get it to activate automatically.

Any time during use the panic button on the front side can be pressed to activate the full alarm mode.

When there has been a lack of motion for 20 seconds an increasingly louder pre-alarm is started. The pre-alarm is re-set when motion is detected. If there is another 10-15 seconds lack of motion after the activation of pre-alarm, the unit enters the full alarm mode with very strong sound and pulsing light warnings.

Once in full alarm mode the unit is re-set by simultaneously pressing the two side buttons. To switch off the unit the accountability key must be first be attached before pressing the side buttons.

A variant is available with temperature sensor and warning for absorbed temperature.
