When a vehicle passes the sensor, an indoor chime unit alerts the occupant. The system operates at up to 400 feet of range between the outdoor transmitter and the indoor receiver. Sensitivity is adjustable from 3 to 12 feet radius, giving installers control over detection width. The transmitter is powered by two AA batteries, not included. Lithium or alkaline AA batteries are recommended for cold-climate installations.\u003c\/p\u003e\n\u003cp\u003eThis unit is suited for residential driveways, gated entries, and light commercial parking area monitoring. It is designed to detect metal vehicle mass only and will not trigger on pedestrians or animals, reducing false alerts. Dip switches on the transmitter allow personalized transmission codes, which is useful when multiple units are installed in proximity. Installation is straightforward and does not require low-voltage wiring, making it accessible to security technicians, electricians, or knowledgeable property owners.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eElectromagnetic detection technology targets vehicles only — does not detect people or animals\u003c\/li\u003e\n  \u003cli\u003eUp to 400 feet of wireless range from outdoor sensor to indoor receiver\u003c\/li\u003e\n  \u003cli\u003eSensitivity adjustable from 3 to 12 feet detection radius\u003c\/li\u003e\n  \u003cli\u003eDip switch transmission codes prevent interference between nearby units\u003c\/li\u003e\n  \u003cli\u003eIndoor chime provides audible alert when a vehicle is detected\u003c\/li\u003e\n  \u003cli\u003eTransmitter runs on two AA batteries; lithium types recommended in cold climates\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a self-contained wireless driveway alarm system for residential and light commercial vehicle detection applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by security technicians or licensed electricians following applicable local codes. Position the outdoor transmitter at ground level along the driveway edge where vehicles will pass reliably within the detection radius. No power shutoff is required for the wireless transmitter, but verify battery type is appropriate for the local climate before mounting. Confirm dip switch codes match between transmitter and receiver before finalizing placement.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDetection Technology\u003c\/strong\u003e: Electromagnetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWireless Range\u003c\/strong\u003e: Up to 400 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDetection Radius (Adjustable)\u003c\/strong\u003e: 3 to 12 feet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransmitter Power\u003c\/strong\u003e: 2 AA batteries (not included)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransmission Code Selection\u003c\/strong\u003e: Dip switches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: 1 year\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: NORTEK SECURITY CONTROL\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FM231\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIGHTY MULE","offers":[{"title":"Default Title","offer_id":51560789049650,"sku":"FM231","price":662.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/dd5cca33b454965f87fe7244962782dc.jpg?v=1786457509","url":"https:\/\/voomisupply.com\/products\/nortek-security-control-fm231-wireless-driveway-alarm","provider":"Voomi Supply","version":"1.0","type":"link"}
