OPEN only (all LiftMaster operators) or SAFETY only (LiftMaster operators with type B2 C2 L2 T T1 or TS control wiring) after vehicle passes over treadle.
The weight of the vehicle compresses an electric switch which sends an open signal to the door.
Requires a 2-wire connection to the operator but does not require power to function
Manufactured to the highest quality standards to ensure accurate detection our Pre-formed loops come with a 50 foot twisted lead-in ware and available lead-in lengths up to 500 feet.
Ideal for use on existing asphalt or concrete surfaces
Features a non spliced continuous wire throughout loop turns and lead-in.
Requires the use of loop sealer when being installed to ensure long lasting trouble-free detection
The CarSense™ 303 features advanced 3-axis magnetoresistive sensing technology.
The sensor measures Earth’s magnetic field and responds to disturbances caused by ferrous objects.
The CS303 combines this exciting new technology with a fieldproven hardware platform to produce a high-sensitivity compact and cost-effective solution for reliable vehicle detection.
Three sensing elements provide magnetic field measurement in the X Y and Z axes improving detection sensitivity.
The photo eyes travel below the door during the closing cycle.
Unlike traditional static mount photo eyes; Patriot travels with the door sensing obstructions prior to contact.
The Patriot2 non-contact system consists of thru beam photo optics.
Emitting and receiving eyes mount into a rigid steel spring loaded retracting housing.
The housings attach to the bottom section of the door and extend below the leading edge of the door providing an invisible infrared light beam of protection.
