Do I need a separate siren or does the receiver have a siren?

Hello, you need to have a siren which usually comes with your alarm system. The seco-larm receivers are just add ons to your system. You can buy a small alarm system for less than $150 on amazon so you can connect the seco-larm detectors.

The siren is activated by DCpower. It is designed to be used on an alarm system. There are no buttons.

You just need the 110 volts to run the siren. The siren talks to the main unit wirelessly without any further power connections

The control pad siren is independent of the other sirens so the answer is yes. In fact, if someone is in my home, I don't want the control pad siren to go off because it will lead the person to the control pad.

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.

Hello, our signal makes ore of a "beep" noise. I would not call it a siren.

On the siren should be a speaker wire harness with some wires coming out look and see which ones are speaker + and. -

There are two components, a transmitter that connects to the doorbell and a receiver that plugs into a 110 V ac outlet. The latter has the speaker that makes the sound. We have one transmitter and two receivers, and I see no reason why you couldn't add more receivers, although as far as I know, you can't purchase them separately. In our case, we ended up with a spare transmitter. You can select one of several chimes at the transmitter, and all receivers make the same sound.

This is just a sensor, so it doesn't produce any sounds itself, but rather just sends a radio signal to the main unit, which then decides based on the current mode whether on not to activate a siren, which BTW is ear-piercing loud.

For the sensor to generate an alarm you need the control unit. They provide a measure of the alarm sound in decibels, but in practice it will depend on where you locate the control unit, but you may add additional siren units to locate in different places.

I used 2 receivers with one transmitter in the past. I know they have a unit with multiple chimes and will receive a few different transmitters. Check the website for the one that fits what you need, or call their tech support. They are very helpful and know their stuff. Hope this helps.

Make sure to go through the list of sellers. Not every seller includes the receiver. The one I bought did not include one, though I already had one from my now busted Wavebird.

I dont have a door/window alarm, but I dont see why you have to buy a separate receiver. You have up to four zones, so you would just set up the door or window detector to anyone of those you have open.

You need EITHER a Receiver (if you want to have also Radio) OR an amplifier.

Nope, backup siren is incase they cut the wires to your primary siren, backup battery is in case they cut the battery power to disable the alarm. If the siren is hard to reach, you will be fine. What many do is pop the hood and cut the power to the battery. I myself just have the backup battery

Yes, I bought mine with the same intentions. I have a ADT system that came stock with internal siren only. You'll just have to take your electric meter out and find which connections are hot when the internal alarm is sounding. Once you find that connection just hook the new ademco siren in with it. FYI, ademco only needs power to sound off....

I didn't purchase the backup siren. It's really just if someone disables your initial siren
