Will this allow me to convert a 1-pulse per second to a constant 12v until the pulse stops? I want to add an aftermarket siren to a factory alarm.

I never tried to use it that way. Usually, it is used to make a dirty signal (irregular) a useable, stable signal. I would give it a try, if I were you. The worst that can happen is that it doesn't work. Sorry I couldn't be more help.

Yes, the pulse would need to be longer than the time set with the potentiometer (set screw). The timer starts when the 12vdc is applied and doesn't active the relay until the timer expires, break the 12vdc and the timer restarts. Hope this was helpful! -Jim

I am not a professional installer but I would say yes. This siren has it's own "driver" built in so it is easy to wire.

Most any 12 volt transformer will do the trick. These sirens don't require many amps to operate to capacity. I'm sure Radio Shack could fix you right up or any alarm supplier.

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.

Siren requires DC power supply to operate. If the motion detector operates on DC you shold be able to.

Sorry, it will not. You need a meter which is calibrated to be compatible with a 12 volt system. You should be able to find one on line as you found this one. Good luck.

Yes. Each of the triggers represents a 15 minute duration. I used mine to power a water pump inside a plant cloning unit. You could definitely set an on 15, off 15, on 15 etc., cycle for a two-hour period, and have the remaining triggers in the 24-hour cycle set to off.Works like a charm.

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.

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.

This is used in a 110-110 Voltage System.. I would not hook it up to a 12 voltage since it was manufacture for a 100-110 voltage system. You can purchase an adopter from Amazon.com. Amazon has everything that anyone could ever need/ want.

Yes. There is an input/output terminal I read of that can be configured to provide voltage on alarm.

Yes, you will need a DC power supply with an output rated within the voltage and wattage range of the siren, a switch and the wire to span the distance from siren, switch, and power supply. Note: the siren has 3 wire leads, usually white, red and yellow. White is common or negitive, and red and yellow are positive but only one is connected at a time. One is solid tone and the other is yelping tone.

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

It works on my 1S cells OK for voltage reading only. However, the buzzer does NOT work with 1S cells. Just plug the JST connector to pins 1 and 2.

Just found this out. If you go to the page on Amazon where they sell the relay and go down to the 5th photo there is a basic schematic. It shows that the pulse wire to active the relay is 12V+ which you need anyway to power the timer. One of the reviews also talks about this as one person wished the pulse could have been 12V- JW

I am not an expert by any means, with regard to the application you describe above, however ;my experience with this PWM, while hooked up to a heavy duty 12 Volt car battery and a Hydrogen producing cell block; performs the VERY same as a Rheostat normally would. I have yet to hook it up to anything below12v(such as the 3.90 A 12 volt power source you mention) and see what results I can get.
