Heath Zenith S SL-5407-BZ 180-Degree Replacement Sensor

Detection Range: Adjustable up to 70 ft. (21m), varies with surrounding temperature

Top Positive Review

Bought this to replace an older sensor that was dying. Purchased it with the “frequently bought together” box and cover, and hooked it up to an existing outside light. To extend the distance from the light, and to make it more visually appealing, I used a flexible power tool power cable I bought at the local hardware store. I included a picture so you can better see how all the items look together.

This part is in the instructions, but just in case you missed it: There are two modes, always on (like a normal light switch), or night/motion sensor (what you are buying it for). You switch modes by turning it off/on in one second. If you get confused about what mode it is in, then leave it off for 1 minute and when it turns back on it will be in night/motion sensor mode.

Amazon Review Heath Zenith SL-5407-BZ-B replacement Tue, Dec 18, 2018 Disappointed is an understatement. I didn??t read anywhere that this was a time delayed unit. Or that the perpetrator had to do jumping jacks to get it to come on; but that is what appears to be happening. I don??t know where it detects a warm body on a not so cold winter night; say around 40F degrees. Due to my health I may or may not be sending it back. But this is not your father??s Oldsmobile. I totally suggest that you seek another brand. Ron /// Update: Mon, Dec 24, 2018: I am returning this unit. Believe what the other reviews say that you can??t get much more than a 30ft detection range. I have worked with motion sensors for over 30 years. I have tried everything I could think of to get this to work right, but it doesn??t go much past 30ft. And it acts like it has a built in time delay. I have an old unit, I would guess about 30 years old on my front porch that almost snaps on when the detection field is crossed.

Customer Questions & Answers

Can I use two of these in paralled to work one light? I want to mount them on the corners of a garage and turn on one central light.
Answer:

My guess is you will burn them out. i tried this once with a water circulation pump (no light in the circuit) connected to a relay. A friend of mine had 3 of these in 3 different bathrooms in his house. the thought was as soon as someone walked into a bathroom, this device would activate a pump which would circulate??

what is the difference between this and the 2020 version
Answer: How should I know consult the manufacturer

Can you put this inside a house detect motion through the house window?
Answer: Even in an ideal setting the range on this device is somewhat limited. I would expect you may encounter some issues with reflection; false alerts or failures to activate. Barring that, it should detect motion over a limited distance.
