FAQ:

Q: How does a tripwire work on an alarm?

A: Once your tripwire is in place, your alarm is ready to use. When someone crosses the tripwire, it will pull the line out from between the screws of the clothespin switch. This will connect the terminals of the button on the transmitter and it will send a signal to the receiver.

Q: Can you change the ringtone on a tripwire alarm?

A: You should always test each tripwire with the receiver in its intended location. The receiver will normally play its standard ringtone as the alarm. If you would prefer to have a different notification, there are several ways that you can change it. One option is to simply change the ringtone.

Q: What happens when someone crosses the tripwire?

A: When someone crosses the tripwire, it will pull the line out from between the screws of the clothespin switch. This will connect the terminals of the button on the transmitter and it will send a signal to the receiver. The receiver will then play its tone to alert you that there is an intruder.
