Doorbell to Alert Entrance

As per Wikipedia, the electric doorbell was created in 1831 by a gentleman named Joseph Henry. I would imagine doorbells in various forms existed way before then though. A knocker at the front door, a bell in the front door, or a good kick to the door.

I know anyone reading this blog wants to know who and when the electric doorbell was created. The Victorians created the first brass bell hop bell

But what about the name, door bell or doorbell, where did that come from?  A Piece of metal attached to hinge, or others used a bell attached to a string. hence the name “door bell”

Pool Safety – Entry Alarm

Have installed a pool at our home a few years ago,  ensuring we kept our children safe was the number one priority.  Where we live, the county required the pool is fenced in and there is some sort of door chime to alert us when the children go outside.  Our home alarm system does send out a chime when a door is opened.  The problem is that the control panel, where the sound comes from is upstairs and the basement door we need to monitor is down stairs – we wouldn’t be able to hear it.

The solution:  The Carlon/Dimango RC2260 Entry Alarm, a.k.a. Entrance Alert

This was so simple to mount.  What you see are the transmitter (the two smaller peices) and the receiver.   The transmitters would mount on the door and you would plug the receiver to where you want to hear the chime.

Long Range Wireless Doorbell

For a long time, wireless doorbells were meant for small or medium sized homes due to their limited operating range. Larger homes had to rely on additional doorbell receivers or on wired doorbell installations. Not any more! Presenting, the wireless long range doorbell. Perfect for large multi-storied homes that require a doorbell on the upper levels of the home. A 300 feet operating range means that you will never miss out on a visitor ever again.

Thomas and Betts Buzzer used in Polar Bear Exhibit

I really thought I had seen it all in this business. A couple of days ago I received a call from a curator at a museum in the northeast. They have a very popular polar bear exhibit and the bear was a little sick. The polar bear needed vitamins or some sort of medicine at regularly scheduled intervals. Every four hours, a dispenser pushes out a marshmallow with the medicine inside. The problem was when the bear was asleep. The marshmallow would push out and as the bear slept during the day, a series of them would start to pile up.

Solution: Connect a Thomas and Betts Carlon Buzzer to the actuator that is dispensing the medicine. Every four hours, when the actuator dispensed medicine, the buzzer would produce a buzz to wake up the polar bear. Wild huh? Trust me, I thought I had heard it all and am anticipating video or photos of the buzzer in action.
