Security Blinker and Buzzer

What form does your motion detecting light kit take?

Blinking buzzer or an audible buzzer and a blinking light? Type of light? Buzzer and light collocated or remote from each other?

Alerting the guard I understand but how does a prowler correlate a blinking light with detection?

I plan to have one light aimed at the spot the motion detector watches, so the light will shine on the prowler and he will know he is spotted. The other light will be aimed down at the security guard area. The buzzer will be right there at the same area, but at a spot where it can't be reached or damaged. It will be loud enough so the prowler and the guard both can hear it.

A regular doorbell should do, I can get one and it's transformer. It's the flasher that I haven't seen in 110 volts.

Check out the ELK Delay Timer "ELK-960." Won't provide the blink function alone, but has many options to provide time-delayed reset. Around $25, I think.

By kit I would think 12 volt so if it is a 12 volt DC lighting system an easy way to make it would be to get a 12 volt auto flasher unit & a buzzer. Depending if you want the light to flash or just the buzzer you might need a relay but if you get an electronic flasher rather than the old type you shouldn't need it.

At my house I have a mains voltage sensor light with an extra wire coming from the load wire of my sensor. It runs back inside my house to the switch & I have a buzzer behind the switch in the wall it is operated from a bridge rectifier with a resistor in series with the buzzer you could also wire an indicator light there. So to have a buzzer at the light put this inside the light or junction box it won't pulse but it will buzz when light is on

Usual Disclaimer here I am a qualified electrician & if you are not qualified I recommend you DON'T do this yourself get some 1 qualified to fit it if you like this idea

I put this in so I know when the light is on & possibly some 1 is in my drive way beside my house. It's great because my dog knows what it means & automatically runs out there when it is buzzing, she reacts differently depending if it is a cat, a faulse trigger or a person there. So I am sure if I can teach my dog to do it the security guards can learn it too lol

Hi Brett,

Usual Disclaimer here I am a qualified electrician & if you are not qualified I recommend you DON'T do this yourself get some 1 qualified to fit it if you like this idea

So, what does "qualified" mean?

I am not an electrician, but I replaced a mains voltage (120VAC here in US) security light just the other day. I didn't even cut the power to do it.

I think that it is good to warn people that there is danger involved, but this is something a non-licensed electrician can do if they know what they are doing (I do).

Just sayin'

i wont react to neighbourhood car alarm coz we have lot of cats here - mostly them - or you have to agree it with your neighbour watch team

donno if it's legal @ your site but

add a smoke generator - complicates - "finding the treasure"
add a random room light strobing
add "psychologically discusting sound" rather than std. alarm (everyone used to)
such as a "rat spooker" for rats in meat industries ~]#[3> (move) ~]#[3> ~]#[3>

add a "random by date time factory" sound from some closed room

There are 110vac flasher units that fit underneath regular incandescent bulbs in normal sockets.

That might be a good start, Tornado. Even if the bell or buzzer is constant, the light would flash.

I'm also afraid of burning out the wiring in the bell or buzzer with longer than normal operation. These things are probably designed for intermittent use.

I picked up a couple of behind-the-bulb flashers today. The spotlite did not want to go into the socket, the flasher took up too much room! Very strange. Even a regular bulb was not wanting to catch a thread, maybe sockets aren't as deep as before.......

Anyway, I tried to have a flasher control the bell, very strange, too. The bell runs off of a transformer, but when I wire in the flasher, it alternates between vibrating and ringing the bell. A meter shows the voltage going off and on, but something is getting through. I put my analog meter in parallel with the bell, and it dropped to 0 volt when the bell was ringing, and went back up to (no load) voltage when the bell was vibrating.

I put the flasher on the 110 side of the transformer. The bell would not work with the flasher on the low voltage side of the transformer.

Also, the motion detector did not like the flasher, the detector did not cycle off after one minute. Without the flasher, it cycled off after a minute. Apparently flashing light is considered motion by the motion detector, so it continued.

Another interesting thing...the bell was rated for low voltage DC, and AC a little higher, if I remember correctly. Apparently it will run on either, but within limits. Another thread was talking about this, I'll have to bring the box home and post the specs.

I think you will find the light sensor is being affected by spikes created by the transformer/ bell switching on & off. I find my sensor lights turn on randomly when other lights are turned on it is mainly compact & normal fluorescent lights that cause the problem but there has been other false triggers from switching on transformers but not as often.

You can hook up the motion detector to a camera and light that calls your cell phone, which can then be accessed and controlled with your phone, add a speaker and microphone, and not only can you see what's going on with your phone you can have a conversation with anybody in the area and record the video to boot...You can have an electronic alarm that can sound any number of audio signals including dog barking, siren, machine gun fire, or whatever...This can be done undetected with infrared light and camera if so desired...

Thanks, Solar Eagle, I'll check it out. I've tried to download webcam software to use with a computer at work, no joy yet. The work computer is not online, so I have to download to this computer, burn to a cd, and then try to install it in the work computer.

I once was called to a friends house to find out why their patio ligt bulb constantly blinked on & off. They were renting & just moved in to the house & what I found was that some 1 as a practical joke had got hold of a flourescent starter switch old style with the bimetal contact & connected it in series with the light bulb & it blinked on & off every few seconds continiously. I do not know what life span it would have but it was quite amuseing & realy peeved them of till I sorted it out.

I have not tried it since but I supose you could use a 110v relay in series with the starter & have relay operate the light & buzzer would be a cheap flasher unit but might not have a long life .
