Secondary Switch Box Control for Aerial Application – 81549001
This component is a surface mount type switch box with controls for
operation of the monitor for use with the OEM secondary RF transmitter.
Separate sealed toggle switches are furnished for up-down, left-right,
and strt-fog functions. The box has a NEMA 4 rating, and is generally
installed at the tip of the aerial ladder, or in the bucket of the aerial
platform. A terminal strip inside the enclosure allows for connection of
the control cable, and a watertight strain relief fitting provides for
sealing around the cable entry
Auxilary Battery Pack – 81492001
A 12-volt, 12 amp-hr. sealed lead-acid battery pack is available to
allow operation of the monitor in case of vehicle electrical system
failure. These battery packs are also used as a means to minimize the
required size of conductors routed up aerial ladders and towers. This is
accomplished by mounting the battery pack near the monitor, with a
small trickle-charge conductor to the battery from the vehicle system
Caution:
Any modification of the enclosures of any of the transmitters or switch box
will destroy the NEMA 4 rating, and will void the warranty coverage. Ensure all O-ring
and gaskets are properly installed when closing receiver or controller enclosures.
DC to DC Converter Function – 24272000
An optional 24 to 12VDC converter board can be added to the RF receiver control module to allow 24
VDC power to the monitor. The converter will supply enough 12VDC power to the monitor to run all
motors simultaneously. It is reverse voltage protected and meets SAE J1113-11 (Immunity to
Conducted Transients on Power Leads) requirements.
