The listing below describes the designation for each color
coded wire on the Mirco Mount Extreme Range traffic signal
preemption transmitter. For complete instructions, refer
to Wiring Diagrams.
|
 |
|
STROBE CONNECTOR - This 3-pin connector
attaches directly to the strobe emitter. Extension cables
are available. Extension cables must be at least #16 AWG
with 600 volt rated insulation.
|
 |
|
BLACK - Battery or Power Supply Negative.
Supplies power to the MicroMount Extreme Range. Do not use
wires rated less than #16 AWG
|
 |
|
RED - Battery or Power Supply Positive
(10 to 15 VDC). Supplies power to the MicroMount Extreme
Range. Do not use wires rated less than #16 AWG
|
 |
|
YELLOW - Diagnostic Lamp or Illuminated
Switch Lamp Negative. Connects to any 12 VDC illuminated
panel switch lamp or any 12 VDC separate panel lamp. Used
for diagnostic purposes. Can be connected to multiple lamps
(see wiring diagram). The other lamp leads(s) connect to
+12 VDC (10 to 15 VDC). Do not use wire rated less that
#18 AWG.
|
 |
|
BLUE - Positive disable input. When
+12 VDC (10 to 15 vdc) is applied to this lead, the strobe
is disabled. Normally connected to a transmission or brake
switch. This wire carries very low current, and can therefore
be rated as low as #22 AWG (recommended wire size is #20
AWG or larger).
|
 |
|
VIOLET - Negative disable input. When
the battery or power supply negative is applied to this
lead, the strobe is disabled. Normally connected to a transmission
or brake switch. This wire carries very low current, and
can therefore be rated as low as #22 AWG (recommended wire
size is #20 AWG or larger).
|
 |
|
GREEN - "Normal" Operating
Mode. When +12 VDC (10 to 15 VDC) is applied to this lead,
the strobe output will be "Normal" (the "Normal"
operating range for a properly maintained system is approximately
1800 feet). This wire carries very low current, and can
therefore be rated as low as #22 AWG (recommended wire size
is #20 AWG or larger).
|
 |
|
BROWN - Extreme Range Operating Mode.
When +12 VDC (10 to 15 VDC) is applied to this lead, the
strobe output will be "Extreme Range" (the "Extreme
Range" operating range for a properly maintained system
is usually more than 2500 feet). This wire carries very
low current, and can therefore be rated as low as #22 AWG
(recommended wire size is #20 AWG or larger).
