Building Controls - Basics
All of the 24V sensors can be used in most building control
systems.
•
In this case no EPV Power Pack is necessary.
•
The voltage supply is taken from the control system, AC or DC
•
ecos sensors can operate on a wide voltage range (e.g. 10.8 – 28V AC
or DC for the On/Off models ).
•
Can be used in most DALI, KNX or similar systems
•
Popular for Home Automation systems
MASTER / SLAVE option for large coverage areas
•

MASTER & SLAVE sensors can be combined to extend the sensor area
(1 MASTER with multiple SLAVES)

•
Use for plugging several 24V sensors together (MASTER / SLAVE)
•
Rule of thumb: Typically 1 unit per SLAVE sensor required.
