In the past you posted a clever setup to create a buzzer notification system. Mouser no loner carries the 21n30p. Will these work in your setup?

The 5 volt output on the 2450 I/OLinc is 10mA.

The sounder you are linking to is 1.5 volts at 30mA.

It may overload the I/OLInc.

Thanks, Brian. I will continue my search.

smokegrub,

 

The 21n30p has been updated. The new part # is 21n30pq

Thanks, I ordered 3 from Mouser. I look forward to building a Buzzlinc or 2 or 3!

You may need to spread the leads of the piezoelectric buzzer slightly to neatly fit the spacing between the COM and 5V terminals.

Stusviews: Understood. That is one of the reasons I purchased more than one, thinking I might break one bending the leads.

I bought five. I now have three BuzzLincs and two spare buzzers

Stusviews: Less expensive to have a few spares. P&H is very expensive on small, relatively inexpensive items. I am going to use two to alert for door openings. I considered flashing overhead lights but this seemed a far better option. I will let you know how it goes.

i\In your directions:

 

"A jumper across GND and N/O on an IOLinc and a piezoelectric buzzer (21N30PQ) from Mouser connected to 5V and COM, voila, an Inseton BuzzLinc.

The jumper is a wire connected to both GND and N/O.

I used two long nosed pliers and my fingers to gently widen the space between the piezoelectric buzzer pegs/wires, one peg at a time.

Push one peg slightly outward with your fingers, then the other. Continue until the distance is wider than what you want.

Using one pair of pliers, grip the peg nearest the buzzer leaving as much of the peg exposed as you can. Use the other pair of pliers to bend the free end inward. Do the same with the other peg."

 

Is the jumper mentioned above the connected pegs?

I inserted the jumper first. Once the piezoelectric buzzer is in place, the jumper is concealed. BuzzLinc
