The Mier 500 driveway alarm system is a hardwired, metal-sensing driveway alarm system.
The DA500CP is the control panel for this system and does not include a magnetic probe or wire.
The magnetic probe and wire can be purchased separately with lengths of up to 2500'. Many different accessories such as light kits, chimes, and whistles are also available for use with this system.
The Mier driveway alarm control panel can be used with any 800-ohm magnetic probe, including the discontinued Winland VAL1 Driveway Alert.
