## Questions & Answers

**Q: Does this make a noise when the beam is broken ?**
A: No.  You must use a relay to power a siren or strobe.   All the beam sensors operate this way.   You have open or closed contacts.   I use 4 of these sensors connected to a niles ipc6 intelligent power controller to turn on an electric fence, a 135 db siren, strobe lights, a laser show and multiple light beams.   All trigger on in a programmed on and off sequence when the beam is tripped.

**Q: Minimum Spacing between sensors?**
A: 6 ft was the shortest distance I achieved

**Q: What is the signal output when a person is detected?**
A: Good day,this item the signal output when a person is detected is 100 meter

**Q: Are they just IR sensors,  what are power supply they need ?**
A: Need 12v power supply,have a Positive and negative

    Not a great product or company!
  

*by T***N on Reviewed in Canada on 25 October 2023*

Ordered the product which took 3 weeks to arrive. Came while we were away on Vacation, so when opened and saw how poorly it was made, needed to return.Thought Amazon would handle this product the same as all other returns-but not so!!When contacting Amazon for a return label, the company sent a postage label that DID NOT prepay the return shipping. (Priced the return shipping and found that it was going to cost nearly $40).Recontacted Amazon, and this Layger then offered a $20.00 credit if we kept the sensors. Not what we wanted considering how cheaply made the sensors are.Paid the $37.00 postage and shipped back. When the credit did not arrived on the C/C, recontacted Amazon.The seller, Layger Products refused to give credit because of their "FINE PRINT" timelines.Now they have both the product & our money! Appeals have been made, but to no avail.Very disgusted with both the seller & Amazon.

    Works well and not that hard to set up.
  

*by J***T on Reviewed in the United States on 26 January 2022*

This review is for a "Dahszhi Dual Laser Detector Alarm Beam Sensor Indoor 300m Outdoor 60m Infrared Detector"This is a reliable alarm that doesn't give false trips and its not tripped by cats, dogs etc. (unless they are over 3 feet tall).  The internal NC/NO switch is rated at only a few milliamps so you'll burn it if you try to drive a load directly.  A few basic components have to be added for a complete circuit.  A relay, transistor or triac, alarm buzzer or equivalent (depending on application) and  a power supply at both ends.  My installation has the receiver and transmitter about 60 feet apart.  The setup isn't hard and tools are provided to simplify it.  A small mirror assembly helps with aiming and a signal strength test point (VDC) makes it so you can tell when the beams are properly aligned.  The most involved part is running wires.===Update:  Had one of these running almost a year now, 24/7 with no problems.  I bought a second set that establishes a beam across the entire width of our front yard and rings a door bell.  Visitors don't have to press a doorbell button because they trip this beam and it does the same thing.  And anyone approaching  the carport trips it as well.These units are well sealed from weather and I've found them to be very reliable.  I was using one with a 12V 30 milliamp relay coil for a while, but that may be pushing the operational limits so I added a simple transistor circuit to reduce the current through the normally open contacts to about 4 milliamps.  A cat was able to trip the doorbell by jumping off the car hood -- through the laser beam, but aside from that, no false alarms.  :)I don't see any issue about how well these units are constructed.  They are built well for the application.  The entire electronics assembly is easy to completely remove from the housing for maintenance if it ever becomes necessary.  Very good product.
