Die cast metal enclosure with standard key cylinder
OPEN/CLOSE spring return to center (OFF) key removable in center position only. Should only be used on operators wired for constant pressure to open and close (all LiftMaster industrial operators with type D control wiring).
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.
For the protection of vehicles doors and safety of people.
Any upward-acting door may be fitted at the leading edge with an electro-mechanical safety weatherstrip.
This mechanism consists of a formed galvanized steel section covered with vinyl impregnated rubber hinged along the full width of the leading door edge.
Can be adjusted to approximately 2½" (63.5mm) to form a tight weather seal.
The hinge linkage is arranged that minimum pressure is required to activate the electrical control switch causing door to reverse direction of travel to the fully open position.
Reverse switch is enclosed in a galvanized housing with a sliding plunger to assure positive actuation every time.
The keypad is housed in a rugged plastic enclosure and is designed to be mounted in a standard single-gang electrical box. The die-cast keys have bright easy-to-read yellow graphics.
It is supplied with four different plastic snap-on mounting bezels to customize the look of the keypad. The satin-chrome bezel comes factory installed on the keypad. The white ivory & bronze bezels are packaged separately.
Up to 480 entry codes from 1 to 6 digits in length can be programmed. They can activate either or both of the relay outputs.
Relay #1 has a 5 Amp capacity. Relay #2 has a 1 Amp capacity. The relays can be set for timed or latch-on/latch-off toggle operation per each individual entry code.
The on or off toggle state of a relay is maintained even after power interruption. When power is restored to the keypad each relay will assume the state it was in when power was removed.
