4.7 Units Field Usage
4.7.1 Protection
1) The Remote Units on field are subject to burning fallout with consistent
risk of permanent damage of the plastic front-panel. An excellent
protection is offered by the sturdy plastic case an the top cover (the
lateral opening on the cover allows the cables to pass and the normal
operation is possible while the COVER IS CLOSED) A further
protection (mainly to avoid damages to the Unit's case) can be obtained
using the special fiberglass covers (supplied upon request as special
accessory).
2) Should the user decide to provide otherwise to the Units protection, it is
suggested to cover the top panel with aluminum foil paying great
attention to avoid any SHORT CIRCUIT between the line wires and
mainly to AVOID ANY CONTACT WITH THE ANTENNA
CONNECTOR (it must be always perfectly insulated and must be never
in contact with other metal parts).
3) The reinforced plastic case of the FIREMASTER IV SYSTEM, thanks
to the particular structure and the IP67 grade, grants a perfect protection
against water spillage or raining. A partial immersion of the Unit on the
water, snow, mud is also possible provided some precautions are
respected:
- The protection plug must be applied on the EXT. BATTERY
connector, the cover must be CLOSED AND LATCHED (see figure
“A”)
- When the ANTENNA is connected and the normal operation is
required, the immersion is possible ONLY IF THE ANTENNA AND
ITS CONNECTORS ARE COMPLETELY ABOVE THE WATER
LEVEL: this will reduce significantly the immersion level (see figure
“A”
- When the normal operation (with the antenna connected) is required
under extreme raining conditions, it is strongly suggested to operate the
Unit WITH THE CASE PLACED VERTICALLY: this will give much
more space between the ANTENNA base and the water surface or wet
soil (see figure “B”).
