AIRHORN – Airhorn tone:
• Activating the AIRHORN button will always produce a higher frequency
AIRHORN tone on speaker 1 and a Lower frequency AIRHORN tone
on speaker 2 until released.
MICROPHONE – Public address:
• Activating the Push To Talk switch on the microphone will put speaker 1
in public address operation and will momentarily shut down any other
siren function until the switch is released.
Lighting Control Operations:
Lighting Control Switches: The lighting control switches include the
slide switch and the 8 momentary switches. The slide switch having one
off position and three active positions combined with the 8 momentary
switches makes a total of 11 lighting control switch positions. For each of
the 11 switches there are corresponding relay controlled outputs on the
connectors of J1 and J2 (see wiring diagram). The following list describes
the Factory Default switch activated outputs.
Slide Switch Positions:
0 = output OFF (Stops HF cycle / Section 5 - Note “B”)
1 = output J2 pin 1 (GRN) (Stops HF cycle / Section 5 - Note “B”)
2 = outputs J2 pin 1 (GRN) & pin 2 (BLU) (Stops HF / Section 5 - Note “B”)
3 = outputs J2 pin 1 (GRN), pin 2 (BLU), pin 3 (WHT), and start the sirens
STANDBY hands free cycle.

Traffic Advisor Control
There are two programmable “Switch Types” associated with Traffic
Advisor control, “Traffic Advisor Pattern Control” and “Traffic Advisor
Flash Control”.
When a switch’s “Switch Type” has been programmed as “Traffic Advisor
Pattern Control”, this switch now takes control of designated Traffic
Advisor output J2 pin 4 (white yellow) and the associated relay output of
the programmed switch. These two wires connect to the traffic advisor.
The first press of this switch will produce a Left sweep on the Traffic
Advisor, and will turn off a “Traffic Advisor Flash Control” switch if one is
active.
A second press will produce a right arrow.
A third press will produce a split arrow.
The next press returns the unit to Left arrow and the cycle repeats itself.
Holding the switch down for 2 seconds will shut the arrow off.
NOTE: Only one switch can be programmed as a “Traffic Advisor
Pattern Control” switch, If more than one switch is programmed,
unpredictable results will occur.
When a switch’s “Switch Type” has been programmed as “Traffic Advisor
Flash Control”:
Pressing this switch will produce a flash pattern on the Traffic Advisor
indicator, will turn off a “Traffic Advisor Pattern Control” switch if one is
active, and the relay output programmed for the “Traffic Advisor Flash
Control” switch will turn on.
Pressing this switch again will shut the arrow off.
NOTE: Only one switch can be designated as a “Traffic Advisor
Flash Control” switch, If more than one switch is programmed,
unpredictable results will occur.
Diagnostic Indicators:
While the siren is under normal use the diagnostic indicators are used to
indicate fault conditions within your siren system. The following table lists
the type of fault and the indicators response. If the indicator is on steady
while a tone is in use, this indicates that there is no fault with the associ-
ated speaker output.
Under voltage: LED #2 will be in DoubleFlash mode and siren tones will
not operate.
Over voltage: LED #1 will be in DoubleFlash mode and siren tones will
not operate.
Speaker # 1 short circuit: LED #1 will be in SingleFlash mode and siren
tones will not operate on speaker 1.
Speaker # 2 short circuit: LED #2 will be in SingleFlash mode and siren
tones will not operate on speaker 2.
Speaker #1 open circuit: LED #1will be off all siren tones will continue to
operate.
Speaker #2 open circuit: LED #2 will be off all siren tones will continue to
operate.
DoubleFlash: 2 quick flashes followed by a longer pause.
SingleFlash: LED will be on and off an equal amount of time.
