Raising The Mast; Aiming The Remote Control Positioner; Stowing The Mast - Will Burt Night Scan Chief Installation, Operation & Maintenance Manual

Auto-Up function is accomplished by two rapid sequential activations of the "Mast Up" button
within a half second period of time. This automatic unattended sequence can be aborted at any
time by a single activation of the "Mast Down" button or any other button on the Remote
Control(s). The Auto-Up function will only bring the Chief from the horizontal stowed position up
to the 90º position and turn the lights on. It will not raise the mast any further vertically on its
own. The Auto-Up function is not available on the non-NFPA Chief.
Wireless Held Remote Control
•
The wireless remote control accepts switch activations from the operator and transmits to the base
control board. If the operator engages a switch, the Remote Control will appropriately send
commands repeatedly as long as the operator continues to engage that switch. The Base control will
pass along appropriate serial commands to the RCP in response to the Remote Control(s). Feedback
in the form of LED's is not available with the wireless remote control.

3.6 RAISING THE MAST

Operation of the mast using the Remote Control(s) is fairly intuitive. A typical operational sequence could
be as follows:
•
Pull the Push/Pull Initiate button.
•
Press and hold the "Mast Up" button on the Remote Control(s) until the mast has fully
extended.
•
Press the desired Pan and Tilt buttons until the lights are facing appropriately.
•
Press the Light and Aux light buttons momentarily to turn the desired lights on and off.
•
Press the "Mast Down" button until the mast has completely stowed.
Note : In the Night Scan Chief, during the process of raising the mast, the mast will first be inclined to a
position perpendicular to its mounting surface by an actuator. Once the control senses it is in this position,
air pressure will be applied to the tube sections to raise the mast further into the air. Lowering the mast is
in reverse order. Air is vented from the tube sections reducing its height. Then the actuator declines the
mast until it is finally stowed.
Auto-up Function (wired handheld remote control only)
The "Auto-up" function can be initiated by giving two quick successive depressions of the "Mast Up"
button (within ½ second). The mast will then raise to the 90° position and automatically turn on both
banks of lights. This automatic sequence can be aborted by pushing any of the buttons on the Remote
Control(s) at any point during the Auto-up sequence. The mast will not extend up by itself, but will await
further operator input from the Remote Control(s).

3.7 AIMING THE REMOTE CONTROL POSITIONER

The positioner can be "aimed" by utilizing the pan and tilt buttons located on the Remote Control(s). The
Pan Left and Pan Right buttons allow horizontal movement, while there are independent Tilt Up and Tilt
Down functions for vertical adjustment of each side of the RCP.

3.8 STOWING THE MAST

There are two methods of stowing the mast. The normal method involves pressing and holding the "Mast
Down" button until the mast is fully stowed and the control shuts itself off. A second method, available on
