I have an old Radio Shack alarm system that works, but needs a new siren. However, it has 16volts at the horn will this one take that much voltage?

I think you should be fine,the alarm duty cycle is usually short and this horn is fairly inexpensive. I'd try it. Good luck.

can this be powered by a car battery? YES (car battery 12V VDC) Supply Voltage 12~240VDC or 24~240VAC What I need is a loud horn or siren to go off if someone comes through a door Switching Capacity 250VAC/1A, 30VDC/2A Relay Output with 12 V max 2A = 24 Watts

I never tried at 6v. Was still loud at 9v. Make sure you have enough mA supply to power this siren. I had to add another 12vdc power supply and relay to use this siren on my simon xt. Your 6v system would trigger the relay to send 12vdc from the new power supply. Good instructions are online.

It is another siren. Its like haveing a extra speaker. I have one that goes off in my house and this one is for out side on my system. They work off the same alarm. My alarm is set up inside the house. Thats were it is tripped from. I hope this helps.

i made a circuit with a limit switch, a 12v timer relay, and this siren. It all operates off 12v. I got a selectable power supply from wally world that plugs into the wall. the siren would actually operate off less voltage but for the sake of the total circuit, 12v was best.

These small alarm horns draw practically nothing. They operate on 12 volts DC and can be fed from your alarm panel with #22 alarm wire. As far as amperage draw goes, I wouldn't even concern myself about it it's so small an amount.Hope this helps.R

I am not sure what ADT you have. But if the output to the siren is 12Volts DC and at least 0.5 amps current capabilities, the siren will work fine. Note it is polarity sensitive so be sure and attach the red wire to (+) plus and the black wire to (-)minus.

Unfortunately the horn will only work on 12VDC. I also would not buy another as it's no louder than the OEM horn that came on my motorcycle.

It will work, but the AC adapter is the big drawback, which is why I when with a hardwire siren, which draw it's power from the control panel ( there are terminal in the back for the connection).

It will work just fine as long as you don't draw over .55amps per feed. If you need you can parallel two 12vdc supply circuits.. Most components in alarm units will function from 6-18vdc...BE SURE WHAT THE OPERATING VOLTAGE IS REQUIRED FOR YOUR APPLICATION.....

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.

The OUTDOOR or EXTRA sirens (not the little one that comes with the main unit for indoor use) - does need 110v outlet (it actually uses like 12v - the transformer is in the plug - so don't be tempted to cut the plug and wire direct or you'll fry it. - yes - I did just that. :( but thats all it needs - it doesn't need any other wiring from the alarm - the activation comes thru wirelessly and yes they are very loud. Also - I've called the Fortress tech support a couple times to ask about other accessories, etc. and he is VERY VERY helpful and calls back fairly quickly if he can't answer so don't be afraid of purchasing this unit. We installed our entire system in 2 buildings in about 25 minutes. The stick-on door sensors have fallen off a couple times (triggering the alarm) - but we just took them down and screwed them in. I don't think we cleaned the surface very good so the glue didn't stick. I had a dif. system and never used it - so I upgraded to this system and love it - its so simple to operate.

It worked fine on mine. You must watch mA draw from all other components of the system you put together though. I believe the 20p provides 2000mA and the Elk siren draws apx 1000 mA, but you can easily add other keypads, indoor sirens, etc till you exceed 2000mA and then it would not work without adding another DC power supply.

I used this siren to replace one that had gone bad on a Honeywell Ademco 20P hard wired alarm system. I believe that the siren/bell hookup was 12v DC on the alarm contacts. This did not require me to install any separate adapter. The siren works very well on my system.

Yes, the adapter come with this siren. It converts the AC power from the wall to 12 volts DC and the siren is quite loud :-) Paul

No! Techno geeks will tell you yes. Experience tells you no. You need a voltage reducer for a 48 volt system or there is a good chance of ruining it.

Hi Christal it will work with any alarm that already has a siren. You will not be able to program different voices to it , that is another module that is extremley hard to find its only availble in the Asian market as far as I know. Hope this helps you. Have a great day.
