How do I tie in a SP switch into the BZ50? Will SP override the Bz50?

Asked by: Bob27

Please see attached diagram. If the switch is installed after the BZ as indicated, it does not override the BZ and attached sensors.

I wired everything the way it says in the diagram but my motion sensor isn’t turning my lights off when I leave for 20min and the power back BZ-50 class 2 is flashing every 5 seconds seeing what the issue could be thanks.

Can you use the Red 24VDC from 1 BZ-50 and connect to the blue input on another BZ-50 to control a load

Asked by: Luke

Hi Luke, No, you cannot hook up as described. Please follow the wiring diagram below to control more than one BZ-50 power pack from a single sensor.

What is the Source/Sink limit in mA of the Blue Control Output wire?

Asked by: Paul Schmid

The transformer in the BZ-50 provides up to 225 mA of 24VDC power for the low voltage devices. The relay in the BZ-50 is switching and therefore does not have a Source/Sink mA limit. The relay will output either 120v or 277v depending on your input voltage.

Trying to put these in an existing building, can I switch the power pack on and off with a switch in the room? Instead of the switch leg coming off the BZ-50?
