Connecting the Siren to the Battery
This section has instructions for making the power connections from the SmartSiren to the battery.
Required are an installer-supplied in-line fuse and wiring of an amperage capacity sufficient to handle
the total vehicle electrical loads.
BATTERY EXPLOSION—To avoid a battery explosion, always disconnect the
negative battery cable first and reconnect it last. Avoid causing a spark when
connecting near or to the battery. The gases produced by a battery can cause a
battery explosion that could result in vehicle damage and serious injury.
HIGH CURRENT ARCING—Do not connect this system to the vehicle battery until
ALL other electrical connections are made and you have verified that no shorts
exist. High current conductors can cause hazardous sparks or burning wire
resulting in electrical fires.
Preparing to Connect the Power Leads
Before connecting the amplifier/relay module to the battery, ensure that your final installation
goes smoothly by taking these preparatory steps:
1.
Check all connections and wiring to ensure they are correct and secure.
2
. Ensure that there are no loose strands or other bare wires that may cause a short circuit.
Protect all wires from any sharp edges that could eventually cut through the insulation.
3.
Verify that are other electrical connections are completed and that no shorts exit.
4.
Use an ohmmeter to verify that a short circuit does not exist between the positive (+) and
negative (–) battery cable leads. Also, there must be no short circuits between the positive
wires and the vehicle chassis.
Connecting the Power Leads to the Vehicle Battery
See Figure 3.15 on page 36. The installer-supplied red (positive) and black (negative ground)
power leads from the siren amplifier/relay module to the vehicle battery should be as short and
direct as possible.
1.
Route the red lead and black lead from the siren to the battery.
2.
Crimp a ring terminal on the red lead and connect it through an in-line fuse to the positive
(+12V) battery terminal. The fuse must be of an amperage capacity sufficient to handle the
total vehicle electrical loads.
3.
Crimp a ring terminal on the black lead and connect it to the negative (–NEG) battery
terminal.
4.
Reconnect the positive cable to the vehicle battery and tighten the clamp.
5.
Reconnect the negative cable to the vehicle battery and tighten the clamp.
