If I connect directly to 12 VDC will it work as an alarm horn.

No. This is a standard 8 ohm speaker and requires an amplifier to drive it. Running a voltage through it would only produce a single 'click'.
1194035
No, it is not a stand-alone alarm horn that is tripped simply by applying voltage; it is a hailer requiring a signal source (voice/music/alarm). It is simply a speaker.

Probably as long as it has 12 v. Also you need access to open air to hear the siren which is in the control unit.

The box says 200ma at 12vdc which is 2.4va. Personally, I use a 12v battery (NP4 - 12V, 4.0ah) with a 300ma charger attached to it to power my whole alarm system, of which the alarm siren is a part. The charger is a simple 12vdc adapter that plugs into the 120 vac outlet. The purpose of the charger is to keep the battery charged, while the battery is expected to do the heavy lifting for powering the siren, buzzers, etc.If the siren is a part of an alarm system, you would want the battery to be the main power supply in case the electricity is disrupted for some reason.

I'm not 100% sure but I think you'd need a 9 volt adapter, not a 12 volt. Try this one

Yes but if you find it is drawing too much current, ie. Panel is inoperable when siren going off, or siren sounds weak or distorted, you will need to use and external power supply and relay

Horn operates on 12 volts DC. If scooter operates on 12volts or you able to find 12volt power source on scooter it will work. Horn is very loud would not use indoors.Hope this helps

You could use an SW-433 and plug in a 12VDC at about 1.5 Amps power supply that would run a regular security siren.And you could run the 12 VDC 2 conductor wire out side to the siren. ( and keep the 120VAC inside the house).I actually have a 12 VDC power supply turned on when triggered by a alarm signal. The alarm signal goes to a relay board that turns on the 120 VAC to the 12VDC power supply and the 2 sirens are powered by it. Takes a load off the alarm board.

Truthfully,I have not used it with 12V DC but clearly I don't see a reason why will it not work as all it is doing is relaying the signal. Question is whether it can stay awake with 12 volt or not. I am not sure but I am certain it will not cause any damage to the unit by you trying 12 volt input. Hope this helps...

Yes, no problems using with a 12 Vdc system. Remember to check the packaging for the small, clear plastic hose adapter if you inlet and outlets are different sixes.

No, unless you are installing a Viper alarm system in a non car application. It has a specific plug.

I used a standard 12v plug in DC converter to an outlet which is controlled by my sensor system. If the security light has an internal sensor it may be hard to use it power the siren.

Most alram systems have a 12volt DC output for the siren or in your case the horns. Send that postive voltage wire to the plus terminal and the negative terminal gets connected to ground.ED

Yes. My primary siren is for the outside of the house. The alarm 5, 115 db is for the inside of My house. There should adequate electrical capacity in your system to add the additional siren. It should be compatible with your system.

Hi there fellow "alarmist"! My siren has three leads: White, Red, and Yellow. White is negative. If yours has a Black wire instead, it's negative. Red to Positive makes the Siren YELP. If you connect Yellow to Positive, the sound is Steady! That's all there is to it... It operates on 12 VDC.Have fun, Walley Bendz

The 12 volt negative would connect to the negative lead of the 12V accessory you are powering.

No. Or at least not directly. You could wire the extra output (usually used for a trunk release) to a remote start unit, but that ends up being awkward. You'd probably want a different alarm.

No- the device is made for small motors, like kids toy cars, a few amps at most and 12 VDC.
