HTZsafe Driveway Alert

I found these sensors on Amazon that are like the ones made by Dakota, but cost half as much. They shoot three IR beams up to 300 ft, between the sensors, and all three beams have to be broken to trigger the alarm. I was looking for a solution to false alarms. After working good for a couple years, my “Mighty Mule” was false alarming all the time, I needed something else.
I bought four, 4 ft by 1 1/2 in galvanized pipes, and mounted the sensors to those. I think the instructions could have been a little more clearer, but got the two pairs of sensors in as zone 1 and zone 2. The receiver has dry contact connections and this is where Smartthings comes in.
I used two Ecolink 2.5 open/close sensors. Walking out in the driveway with my app open I could see the Ecolink open when I broke the beams. Success.
So now, when the sensors trigger, Alexa says “Someone is in the driveway”. I also get a text message, (set up in Smartthings under ‘notify me when’)
Going for three weeks now, and no false alarms. It’s got every car coming in the driveway. Below are the ones I ordered, and I added two more sensors for another $99

This gives you an idea of how the sensors look, and the distance I placed between them

Didn’t try it, but I think I could have used one pair of sensors to cover both my drives.

They come with the hardware to attach to a pipe, or a flat surface.

Hey dan, I have the same issue, I got the same products as you, but I was wondering if you could give a couple of closeup pictures on the wiring on the alarm unit. Especially inside the ecolink sensor. I see 3 connections for each zone on the HTZSAFE alarm unit, which ones did you connect? Also what gage of wire did you use?

Thanks in advance,
Jeff

Jeff, Looking at the alarm unit, I wired to the two spots on the left, out of the three. This gives me “normally closed” when I look at the sensor in my Smartthings app. I used 22 gage phone wire.

I also opened up the back of the alarm unit, and there are four rows of connections, each with a jumper you can pull off and move. On the far left row, I moved the jumper to “10 seconds” . This is the time it takes the alarm unit to reset the dry connections before it can be re-triggered again. I don’;t remember what it was on originally, I just thought 10 seconds would be a good choice. I think there is a 1 second also. But this works for me. i really like this system. Still no false alarms, and it’s got everything coming in the driveway.

Awesome you are a gentleman and a scholar. One question do you have a spec sheet for the circuit board for the EcoLink? I couldn’t find one when googling…

Sorry Jeff, I do not.

No worries, got an operational question for you. The sensors with the solar cells are beeping really loudly when the beam is broken, any idea how to disable that? Or was it maybe just cause I was levelling them?

Jeff

Ok, here’s what you do to put the sensors in stealth mode.
Press them three times to turn them off. Once off, press seven times. That will mute the beeping.

Thank you sir, how did you find that out? The manual I got was pretty sparse…

There’s a YT video of it. Glad to help you out.

link plz if you still have it

I took a quick look on YT and couldn’t find it. It’s probably in there somewhere. On the Amazon page for that unit in the Q and A;
Question:

Is there a way to disable the beeping that occurs on the sensor after the beam is broken? I’m trying to alert myself, not my visitors.

Answer:

Hi there, please kindly find the details below:

  1. If the beam sensors are ON status, please turn off the sensors first by pressing the ON/OFF button 3 times , and then turn on the sensors again by pressing the ON/OFF button 7 times.
  2. If the beam sensors are OFF status, please turn on the sensors by pressing the ON… see more

This is the video where I learned how to move the jumpers inside the receiver.
