DIY Installation Guide: Siren and Alarm Siren
When we speak of siren, we usually think of the one that we hear loudly wailing in police mobiles of federal law enforcers. There are also sirens that are made for the usage of fire trucks and ambulances. Much like the ones in police mobiles, these sirens announce the presence of a specific type of vehicle to the public, enabling an effective dispatch on emergency situations. Large vehicles also have powerful truck air horn sound. Newer vehicles, on the other hand, often come with alarm sirens that act as theft-deterrent devices. You can also have one installed to your car.
Difficulty level: Easy
What you'll need:
- Insulated tie wire
- Crimping tool
- Electric tape
Step 1: Have a vivid picture of an installation outline. If possible, draw it. Car manuals will greatly reduce the planning time, feeding you with the necessary information regarding wiring colors, locations, and polarities.
Step 2: Prepare the device in as tidy way as possible. Set aside those that shall not be used with insulated thin tie wire. Bundle together the wire that are of similar purpose. There are those that will be wired through the body control modules, driver side kick panel, and the ignition switch. So you really have to be familiar about the use of every single wire in the car alarm assembly.
Step 3: Carefully inspect your car for any flaws. Give particular attention to the door half-open indicator on the dashboard. Fix any problem with the trigger first before installing the alarm siren so as to prevent the alarm from incessantly wailing or from being ineffective.
Step 4: Remove the parts of the dashboard and other interior panels that will house the siren wiring assembly.
Step 5: Find a mounting area that will discreetly hold your alarm siren. Some choose to have it under the hood with the speaker faced down, while others find it easier to install in the inner fender. If you want it under the hood, ensure that it is far enough from the heater core and the exhaust manifold that generates heat.
Step 6: Mount the siren to a portion where the screws will not damage any lines and cables. You can also use nuts or bolts to safely hold the siren in place.
Step 7: You can now wire your siren. Drill first a hole through the passenger side firewall by the grommet. Feed the wire through it in order to reach the passenger compartment. The power wire of the alarm siren system, on the other hand, should go the other way around to have it connected to the battery.
Step 8: Install the control module on the dashboard by the steering column; ensure stability. Also install on your dash the LED indicator. A hole needs to be drilled for its wires as well. Install the alarm siren sensor on your chosen location, and connect its wires to the door light button and power lock wire.
Step 9: Complete the connections. Connect the LED indicator, power wires, sensor, and the siren to the control module. Insulate the connections with electric tape, and secure them using a crimping tool. Finish the wiring installation by grounding the wires on the control module.
