What else do I need to activate a horn/siren for say 1 minute when the light beam is broken.

This photo sensor will provide the signal when the light beam is broken, but that is all. I presume you'd need the siren and some sort of controller. I don't know what that controller might be, but this sensor is often connected to a gate operator controller or an alarm system controller, or that sort of thing. By the way, I have this sensor on a gate entrance to our property and it works great to prevent the gate from closing when the light beam is broken.

You will need a speaker with a self contained driver, a 12v power supply and a timer module.

You would need a relay with a timer. The beam will trip the relay and the relay will hold power to your siren for the time set on the relay and then release.

If the time the siren needs to be on is different then the time the light beam is broken, you would need a timer relay.

When the power is cut, the external siren is inoperative, but the siren in the control head continues to operate (internal battery) if triggered. I do not know how long this battery lasts.

It is just a sensor that will activate a separate alarm system when something or someone breaks the photoelectric beam between the two sensors.

Not to my knowledge. When the beam is broken, a wireless signal is sent to a dedicated receiver that gives off a chime. That's it. Even then, it works only about 75% of the time. I am still looking for a system that works 100% of the time.

Push the button once for high beam and another time for low beam and once again to turn it off. You can turn the low beam on from the off position in about two seconds and one second if the light is in the high beam.

There is a delay when the siren sounds and the call is made. I do not know if that's the question?

Don't apply as much pressure and the laser won't activate......their is an on/off switch..best of luck. If it isn't broke, don't mess with it!!! Please support the 2nd Amendment

Maybe like 3 seconds when it goes off. The sound will activate only when motion is detected.

This siren is just that, a siren nothing else. This siren has to be connected to something that will turn it on and power it.

This is just a siren, not an alarm system. When power is applied, it makes a loud noise. And when no power is applied, it is silent.

I don't think our car (bought at the end of 2012) has a siren. Or, maybe our siren doesn't work. The lights flash though.

just the siren/strobe and the plug/transformer. you need the security system for it to work.

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
