2.0 DESCRIPTION
Pan/tilts in the PT1280P Series are heavy duty pan/tilts capable of handling loads
up to 100 lb. They feature rugged high torque AC motors with adjustable worm gear
final drives to insure long operational life, as well as drift free operation.
The PT1280 Series pan/tilts are capable of auto/random scan operation with the
addition of the Pelco solid-state auto/random scan joystick control. No additional
conductors, micro switches or relays are required for auto/scan operation.
These pan/tilts are factory pre-wired for feed through of all control functions: pan/
tilt, motorized zoom lenses, camera power (24 VAC), enclosure accessories and
video. All connections are made at the input connector, eliminating the need for
wiring harnesses in the field. This feature greatly reduces installation time, while
increasing the reliability and serviceability of the system.
The PT1280SL has the added feature of 360° pan rotation.
