90-00 Description (continued)
The searchlight is installed on a motorized gimbal under the belly. The searchlight power
junction box is located in the right rear under-seat compartment. The searchlight is steerable
in azimuth and elevation and is operated from the left front seat via a remote control. An
optional slaving system allows the searchlight to be slaved to follow the camera. The
searchlight should be stowed horizontally when not in use to minimize chance of damage
during a hard landing.
CAUTION
The searchlight is very bright and can disorient other pilots or
ground personnel at long distances.
CAUTION
The searchlight beam is hot. Exposure to the beam at close
range for more than a few seconds can result in burns.
An additional observer-side interior light is operated via a momentary foot switch on the left-
hand forward floor. Power is supplied to the interior light via the “GAGES” breaker in the left
hand circuit breaker panel and is not disconnected by the police equipment master switch.
A 100-watt speaker is located on the aircraft belly near the left rear landing gear strut. The
PA system control panel is located in the avionics stack and allows the pilot or observer to
select PA, radio, yelp, or siren for broadcast through the speaker.
A multi-band FM transceiver may be mounted either next to the LCD monitor or in the main
avionics stack. The FM transceiver band(s) are selectable from the audio control panel(s).
The Lojack installation consists of a receiver installed in the main baggage compartment
behind the interior wall, a display and control unit on the right side of the instrument
console, and four belly-mounted stub antennas. Lojack is used to track stolen vehicles
equipped with Lojack transmitters.
The GPS mapping computer is installed in the main baggage compartment behind the interior
wall and allows an overhead view of the helicopter’s area of operation to be displayed on
the LCD monitor. The computer contains a database of streets, landmarks, and topography
enabling direct navigation to street addresses and other points on the ground. The computer
is accessed using a keyboard below the LCD monitor. An optional inertial monitoring unit
can interface with the computer to keep the camera and/or searchlight trained on a fixed
ground location while the helicopter maneuvers.
