Adding Soft Chirp Siren to Keyless Entry

I wish to add an unlock/lock siren to an aftermarket keyless entry kit (Toad RK30). It does not have a connection for an audible alert so Im wondering if this can be done with the use of a relay? I only want the siren to be a momentary signal,preferably by using the turn signal +ve supply from the unit. Can this be done and ifso,how? TIAShaun

The duration of the light flash will not allow "soft chirp" it is obnoxiously long and will be annoying after 2 days of use. It can easily be done if you want to do it. What is easier for you to get? 3 quantity of 3 amp diodes or a relay?

Thanks to I am an Idiot(Not!!) I connected the siren to the turn signal+ve output without the use of a relay,and immediately decided that it would drive me mad,as the soft chirp,well didn't . Relays are much easier to get than diodes,(for me),although I could no doubt find some diodes online if required) I'm hoping that you may have a circuit diagram that allows the soft chirp from the turn signal using relays...

If you are using the positive light output for the lights you will need 2 relays wired as follows. positive light output from keyless module to terminal 86 of both relays. constant 12 volts to terminal 30 of both relays. Ground to terminal 85 of both relays. 87 of 1 relay to the positive light wire of the vehicle. 87 of the other relay to the sirens positive wire.

Thanks for that,although I dont understand how this circuit will give me the momentary chirp I am after. Maybe I am missing something?Shaun

I connected the siren to the turn signal+ve output without the use of a relay,and immediately decided that it would drive me mad,as the soft chirp,well didn't . I read the above line as you thought it would drive you mad with the length of the chirp, and at the end you said it didn't. There is a way to shorten it. I will get you a diagram to shorten it tomorrow.

Thanks for your continued help to I am an idiot. My mistake for not finishing the sentence,causing confusion. I should have written that the soft chirp didn't give the desired momentary chirp sound. I look forward to your next post with the required diagram. Shaun Shaun

Thank you to I am an idiot. Im hoping that you are still able to supply me with the diagram to shorten the chirp when connected to the turn signal output. Since your last post I have looked into the pulse relay with adjustable timer: 12V, 10A Adjustable Delay Timer Relay (Delay ON or OFF) https://www.12voltplanet.co.uk/timer-relays.html This may be a decent alternative. Perhaps you could let me know your thoughtsShaun

Get 3 capacitors. 100 uf, 220 uf and 470 uf 1 of the 3, or paralleling 2 or 3 should give you what you are looking for.
