Two BLUE wires - Radio Rebroadcast (optional):
The two remaining BLUE wires are used to connect your two-way radio’s
external speaker for radio rebroadcast (optional connection).
Note: If your remote speaker is amplified (speaker has a power amp circuit),
radio rebroadcast will not work and should not be used.
1.
Locate the 2 wires that connect the external speaker to the 2-way
radio, cut one of them and splice one of the BLUE wires into this
circuit.
2.
Cut the remaining speaker wire and splice the other BLUE wire into
this circuit.
VIOLET - Siren Interruption:
Grounding the VIOLET wire will deactivate the siren.
The siren can be
programmed to reactivate the tones by 2 different methods (See section
6.3)
This wire doesn’t affect HORN or MAN push button operations.
2.2 PINS 10, 11 & 12:
GREEN - Aux Enable:
This wire is activated in slide switch position 3, if switch1 of BANK-1 is
down.
ORANGE - Siren in Use:
Extend the ORANGE to the icon input of a video camera. This wire is
active positive whenever a siren tone is being produced (200ma max).
YELLOW - Backlighting:
Extend the YELLOW to the parking light positive voltage. This input is
used to drive the backlighting of the siren when the power is off.
Alternate Slide Switch Control:
In factory default setup, the slide switch’s common power terminal is
connected to the BROWN wire on P1. By changing a fuse (located by
removing the cover of the siren) from the F4_F2 position to the F1_F2
position, the slide switch’s common power terminal can be configured to
get it’s power from the RED wire of P1 which is used to power the six push
button switches.
3.0 Front Panel:
3.1 Power Switch
This switch has two positions; Up (On) and Down (Off). When this switch
is off, siren functions are disabled, however the power distribution switch-
ing can operate independently of the power switch.
WARNING! If the this unit is connected to the vehicle’s horn ring
circuit, the vehicle horn is disabled when the power switch is ON.
3.2 Rotary Switch
The Rotary Knob controls the siren functions of the
295SLSA5
. There are
7 positions that may be selected
(see Section 4.0.).
3.3 Volume Knob
The Volume Knob controls the volume of Public Address function. Volume
is increased by rotating the knob in a clockwise direction. Rotating the Vol-
ume Knob in a counter-clockwise direction decreases the volume pro-
duced by these features. The
volume knob has no effect on siren tones or radio repeat volume.
3.4 Radio Repeat Volume
Before using the
295SLSA5
, the Radio Repeat output volume must be
adjusted to satisfactory operating levels. To adjust this level, a small, flat-
blade screwdriver is needed. Locate the Radio Repeat adjustment port
(potentiometer) to the right of the Rotary Knob on the face of the control
head. Set the volume level of the vehicle’s two-way radio to its normal
operating volume. Turn the Rotary Knob on the control head to RAD to
activate Radio Repeat. Insert the screwdriver in the Radio Repeat adjust-
ment port and turn in a clockwise direction to increase the sound level.
3.5 MAN Button
The Manual button generates a variety of tones, depending on what posi-
tion the rotary knob is in (see Section 4.0.).
3.6 SI TEST® & Diagnostic Indicators
SI TEST is a diagnostic feature of the
295SLSA5
and allows the operator
to confirm the proper operation of the siren speakers connected to the unit
without activating an audible siren tone. To initiate SI TEST cycle, set the
rotary knob to the RAD position. Now press and release the MAN button.
As the siren is tested, its diagnostic indicator will turn on steady for about
1.5 seconds if no problems are detected. If the indicator flashes, or does
not light at all, a problem with either the siren, speakers, or wiring has
been detected. Check the wire connections of the failed speaker and
repeat the SI TEST. If the speaker fails to test again, have the siren itself
inspected by a qualified technician.
NOTE:
Installed speakers are tested
by generating an ultra-high frequency tone through each speaker.
Although these tones are inaudible to humans, be sure no one is within 5
feet of the speakers when SI TEST is running.
Diagnostic Indicators:
While this siren is under normal use the diagnostic indicators are used to
indicate fault conditions with 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 implies that there is no fault with the associated
speaker output.
Fault Condition Diagnostic Indicators Response
Under Voltage
Speaker LED #2 will be in a DoubleFlash mode (2 quick
flashes followed by a longer pause) and siren tones
won’t operate.
Over Voltage
Speaker LED #1 will be in a DoubleFlash mode (2 quick
flashes followed by a longer pause) and siren tones will
not operate.
Speaker #1
Speaker LED # 1 will be in a SingleFlash mode (the LED
Short Circuit
will be on
and off an equal amount of time) and siren
tones won’t operate.
Speaker #2
Speaker LED #2 will be in a SingleFlash mode (the LED
Short Circuit
will be on and off an equal amount of time) and siren
tones won’t operate.
Speaker #1
Speaker LED #1 will be off (having a single speaker
Open Circuit
system will always cause this condition for the speaker
output not in use) all tones will continue to operate.
Speaker #2
Speaker LED #2 will be off (having a single speaker
Open Circuit
system will always cause this condition for the speaker
output not in use) and all tones will continue to operate.
