Universal sensor input over 30m?

[sarf77 11]

Hi all,

 

I am wanting to use a UBS to trigger an entry and exit scene through an electric gate. The gate is some 30m from the nearest HCL so zwave range will be difficult and unreliable.

If I run a 30m two core cable across IN1 and Gnd out to a magnetic reed switch, Will the UBS still sense the open close contact over that distance? Worst case I could use a 12V relay locally switched by the 30M cable through the mag reed if need be.

IMO This is no different than use with 3rd party alarm PIR’s so should work fine.

There is a limitation for 2-wire bus only (to connect temperature sensors).

Guys just to report back,

 

So it turns out the cable run was around 80m. It was using a 4mm2 twin copper cable. 

 

The UBS is working perfectly. I'm using both inputs over the same distance with the USB right beside the gateway on a power supply.

Very pleased.
