PIR Sensor for Staircase Lighting

[secware3]

 

I’m looking for a PIR sensor that can detect movement both from the bottom and the top of a staircase. Our current sensor is positioned on the wall above the door at the bottom of the staircase, but it only detects movement when someone is about four steps from the bottom. This is creating a safety risk, as the lights aren’t activating until a person walking down is already quite close to the bottom. The staircase is approximately 9 metres long. I have images I can share — please let me know an email address where I can send them. I was looking at the following item and was wondering if it would work for my requirements, or if you could recommend a product that would be more suitable for my situation. Thank you! https://www.securitywarehouse.co.uk/catalog/intruder-alarm-equipment-c-36/movement-detectors-c-36_116/all-c-36_116_37/optex-cx702-21m-wide-or-45m-long-pir-p-157.html

Yes images would be useful to get a better understanding. ALso a drawing where you want detector coverage?

 

You can upload them here

Please see attached images of our set-up.

 

You can see in the white circle that the PIR fitting is located above the main door on the ground floor. Currently, it only activates when someone reaches the 4th step (both going up and down the stairs).

 

We need the PIR sensor to:

 

• Activate the lights when someone walks through the main door on the ground floor.
   
• Also activate when someone is coming down the stairs from the 1st floor.
   

The distance from the ground floor to the 1st floor is approximately 9 metres, but with an incline.

 

Please could you advise on a suitable solution, or confirm whether the link provided above would work for this setup?

 

 

Many thanks,

Due to the chnage of elevation (ie top and bottom of stairs your really going to need 2 sensors. A corridor sensor on a bracket may work well but isnt designed to angled that way. Also bear in mind the link you provided is a intruder alarm sensor not for switching 240v. It could be connected to a relay and suitable power source though. If doing that id recommend a voltek system as they provide adjustable low voltage sensors and it will be easier to run a low voltage alarm cable to the sensors from where the current switching is taking place.
